HOW DOES a horse choke i was wondering how they would.?
it sounds like a horse is coughing up a hairball. or like when a horse is overworked and they make that coughing noise when they run out of air. that's wat it sounds like. horses can choke on objects if they aren't broken up into the appropriate size for them.
How does revolution effect seasons?
the revolution causes the changes of whether and the wherther causes the change in seasons. the revolution causes the changes of whether and the wherther causes the change in seasons. the revolution causes the changes of whether and the wherther causes the change in seasons.
No. Sunspots are related to prominences and flares because they are all caused by imperfections in the Sun's magnetic field. A sun spot is the base of a prominence (they are the same phenomenon) and Solar flares are just enormous prominances. The Earth has no effect whatsoever on the Sun. (Apart from a few very minor technicalities.)
When were space stations invented?
The concept of space stations dates back to the early 20th century, with the first successful space station being Salyut 1, launched by the Soviet Union in 1971. Since then, numerous space stations have been launched and continue to be utilized for scientific research and space exploration.
What solar features can increase the solar wind?
Solar flares, coronal mass ejections (CMEs), and coronal holes are solar features that can increase the solar wind. These events release charged particles into space at high speeds, which contribute to the solar wind.
How often does a King Tide occur at a beach?
King tides occur when the Sun and Moon align, causing higher than normal high tides. They typically occur a few times a year depending on the location and tide cycle, usually during the spring and fall months. The frequency can vary depending on the coastal area and the gravitational pull of the Sun and Moon.
How do light waves appear to an observer as the light source moves towards the observer?
If we measure the spectrum of the light, we can determine whether the light is moving toward us or away from us. Sunlight looks white, but is actually made up of thousands of individual colors, and the amount of each color depends on what the star is made of. In the far future, spacemen will be able to detect which star is which, by measuring the spectrum of the light.
By measuring the pattern of the spectrum, and the exact frequency of the light waves, we can determine whether the light source is moving toward us or away from us. (Actually, that isn't exactly true; we couldn't tell if it was moving toward us, or WE were moving toward IT. But we will know what we're getting closer together.)
There is one other "Gotcha!" about this. If the spectrum indicates that the light source is moving away from us, it is possible that the light source is very near a black hole. Gravity affects light just like it affects mass, and sometimes it is difficult to tell whether the light source is moving away, or if gravity is pulling the light away. Usually, we will be able to determine which is happening from other measurements.
What is a good substiute stainfor looking at onion root tips under a microscope?
A good substitute stain for looking at onion root tips under a microscope is iodine solution. This stain will help to visualize the cells more clearly by highlighting the cell walls and starch grains present in the root tips.
Why does the moon appear larger when it's close to the horizon?
Because it is much closer than all of the others.
The Sun is only about 8 light minutes away from the Earth, while the closest other star to Earth is many light years away. (Alpha Proxima, 4.2 ly to be exact)
What happens when sun shines on the far side of the moon?
Nothing special or unusual happens. Daylight moves around the moon the same way that it moves around the earth and other planets/moons in the solar system. The more of the far side is illuminated by the sun, the less is illuminated of the side that we see.

This configuration is called a"new moon".
What are the people from Earth called?
Presently they are called Earthlings. But that is a belittling name from science fiction. I am a science fiction writer of the first caliber.
.....The best new name for us would be Earthians, to match the convention of calling people from Mars, Martians. Earthians is what I call us in my manuscript novel, "Mars, 2101."
.....Earthys would be a good perjoritive for sleazy Earthians.
.....There will be many Martians created after SpaceEx lands its giant emigration rocket on the Orange Planet. It is not red. Look at the picture! :=] My books are at meeceblog dot wordpress dot com
Why would warm water be considered a water pollution problem?
Hot water can be pollution because if somebody dumps hot water into a body of water, the hot water can kill organisms living there.
Answer:
Hot water (thermal pollution) impacts the receiving water in several ways the alter the environment and ecosystem: * A sudden burst of hot water can kill aquatic organisms by thermal shock. Fish have to adjust to new temperatures slowly. * Continued hot water can raise the receiving water's general temperature. This in turn reduces the oxygen levels so that only more hardy species can live there (carp not trout), encourages the growth of plant life, and impacts breeding success rates of aquatic organisms * Warmer streams encourage birds to over winter, potentially leading to bird kills die to lack of food * Warmer water can leach out metals and organics from the stream bed
What is the layer below the corona?
The layer below the corona is the chromosphere. It lies just below the corona and is characterized by a reddish glow during solar eclipses.
When was the geocentric theory invented?
The geocentric theory was developed by ancient Greek philosophers, primarily by Ptolemy in the 2nd century AD. This theory posited that the Earth was the center of the universe around which all other celestial bodies revolved.
How do contour lines show elevation and slope and relief?
Contour lines represent elevation on a topographic map. Lines close together indicate steep slopes, while lines far apart indicate gentle slopes. Contour lines that form concentric loops indicate hills or depressions, showing a relief in the area.
Where did the first atom come from?
That is one question that defies a definitive answer. Some theorists believe it has always existed (and that sidesteps the question) and others theorize that it may have been created by a race of super inter-dimensional beings and deposited here by way of a wormhole (who knows?!) But all in all, mathematics bears out the fact that it did, indeed, exist owing to the fact that universal expansion, if regressed, would wind down to a singular point (the ''singularity''). Beyond that, nothing is verifiable. But, till mankind has developed higher intellegence and accumulated enough knowledge to answer this question directly, perhaps it would serve to read the book of Genesis and interpret each of the Creator's 'Day' in terms of Billions of years.
How many hours of daylight does Hawaii have?
Year round, Hawaii has between 10 hours 50 minutes and 13 hours 26 minutes of daylight, the least on December 21-22 (winter solstice) and the most on June 20-21 (summer solstice).
This is because at Hawaii's latitude of 20 degrees N, it is affected slightly by the tilt of either pole toward the Sun. The islands are technically in summer during the month of June, July, and August but the angle of the Sun and length of the day are not always the primary factor in seasonal temperature variations. The average day length is about 12 hours and 8 minutes, which occurs on the two equinoxes.
* Some calendars show extreme differences (up to 30 minutes) in daylight length within the same month, and these are not consistently reliable.
Lunar phases are the result of looking at the illuminated half of the Moon from different viewing geometries; they are not caused by shadows of the Earth on the Moon that occur during a lunar eclipse. The Moon exhibits different phases as the relative geometry of the Sun, Earth and Moon change, appearing as a full moon when the Sun and Moon are on opposite sides of the Earth, and as a new moon (also named dark moon, as it is not visible at night) when they are on the same side. The phases of full moon and new moon are examples of syzygies, which occur when the Earth, Moon and Sun lie (approximately) in a straight line.
No, the time taken to travel to another planet in space would not be the same as the time experienced on Earth. Time dilation effects due to the speed of travel and gravitational forces would cause time to pass differently for astronauts in space compared to people on Earth. This means that time would appear to pass more slowly for travelers in space relative to those on Earth.
Does the sun move in a circular path?
Yes. The sun rotates around the Milky Way galaxy (our home galaxy, although only one of billions that we can see) once every 220,000,000 years. There are also other, more subtle motions, but this one answers your question.
Does solar energy come from the sun or from wind?
Wind energy and solar energy are alternative energy sources they are NOT the same, solar energy comes from the suns heat while wind energy comes from the wind. Solar energy is generally collected with solar panels while wind energy is generated when the wind turns wind mill like structures that in turn, turn turbines that generate electricity.
Describe the difference between a solar flare and a solar prominence which affects us and how?
The difference between a solar flare and a solar prominence is that a solar flare emits charged partials, which travel to the Earth. Solar prominence are large sheets that burst out from the Sun that last for days or even weeks and can grow up to 400000km high. A solar flare affects us by emitting charged partials to the Earth. When the partials hit the Earth the Earth's magnetic field forces them to the North and South poles. As this happens it produces an electrical effect in the Earth's atmosphere that interferes with transmission of radio waves. This is why many communities in the far North lose radio communication for many days at a time.
It took my a very long time to figure this out. if you are doing this for a science isu in grade 9 them it is on page 453 on the bottom left of the sun diagram.
Members that can interbreed and produce fertile offspring are usually in the same species. This is because a species is defined as a group of organisms that can interbreed and produce viable offspring. The ability to produce fertile offspring signifies a higher level of relatedness and genetic compatibility between individuals.
The world's official timekeepers have added a "leap second" to the last day of the year on Wednesday, to help match clocks to the Earth's slowing spin on its axis, which takes place at ever-changing rates affected by tides and other factors. The US Naval Observatory, keeper of the Pentagon's master clock, said it would add the extra second on Wednesday in coordination with the world's atomic clocks at 23 hours, 59 minutes and 59 seconds Coordinated Universal Time, or UTC. That corresponds to 23:59:59 GMT, when an extra second will tick by - the 24th to be added to UTC since 1972, when the practice began. UTC is the time scale kept by highly precise atomic clocks around the world, accurate to about a billionth of a second per day, the Naval Observatory says. For those with a need for precision timing, it has replaced Greenwich Mean Time, or GMT. The decision to add or remove a second is the responsibility of the International Earth Rotation and Reference Systems Service, based on its monitoring of the Earth's rotation. The goal is to make sure clocks vary from the Earth's rotational time by no more than 0.9 seconds before an adjustment. That keeps UTC in sync with the position of the sun above the Earth. Mechanisms such as the Internet-based Network Time Protocol and the satellite-based Global Positioning System depend on precision timing. The first leap second was introduced into UTC on June 30, 1972. The last was added on December 31, 2005. They have been added at intervals ranging from six months to seven years, Daniel Gambis, head of the IERS Earth Orientation Centre at the Observatoire de Paris, wrote in an explanatory piece this month (http://hpiers.obspm.fr/eop-pc/). Among the reasons for Earth's slowing whirl on its axis are the braking action of tides, snow or the lack of it at the polar ice caps, solar wind, space dust and magnetic storms, according to the US Commerce Department's National Institute of Standards and Technology, another timekeeper. By contrast, a leap day, February 29, occurs once every four years because a complete turn around the sun - our year with all its seasons - takes about 365 days and six hours. In 1970, an international agreement established two time scales: one based on the Earth's rotation and another on highly accurate atomic clocks. The US Naval Observatory's master clock is based on a system that now includes 50 atomic clocks, 36 based on the element cesium and 14 known as hydrogen masers. With the Earth's rotation gradually slowing, the periodic insertion of a leap second into the atomic time scale is needed to keep the two systems within a second of each other.
Be very careful how you interpret the adding of leap seconds, though. You might think that the addition of 24 leap seconds since 1972 (or whatever the current count) means that the earth is now rotating at 24 seconds per day slower than it was in 1972. This is not the case; the real explanation is counter-intuitive.
What are 3 characteristics of main sequence stars?
Main Sequence stars are an average size, and as the surface temperatures of the star increase, the luminosity increases. The luminosity increases from red to blue-white is mostly related to an increase in star size and the resulting higher temperatures.
