Those are three different questions; you would be better of asking them as three different questions on this site.
The difference between rotation and revolution is that "rotation" refers to a movement of an object around its own axis; while "revolution" refers to a movement around an external object or axis - in this case, around the Sun.
What is the shortest day of the year in ND?
The shortest day of the year is December 20 or 21 (it varies because of leap years) for any point in the northern hemisphere. This is called the "winter solstice".
In the southern hemisphere, the shortest day of the year is June 20 or 21.
What is the meaning of Head is in the clouds?
The phrase "head is in the clouds" typically means that someone is daydreaming or not paying attention to reality. It suggests that the person is not grounded or focused on what is happening in the present moment.
What happens if you dont have any oxygen in space?
Without oxygen in space, a person would become unconscious within seconds due to the lack of breathable air. This would be followed by permanent brain damage and eventually death within a few minutes. Spacewalks are only possible with the use of a spacesuit that provides oxygen for breathing.
What is the name of the first satellite sent to space?
The first satellite was launched into space by the Russians on the 4th of October 1957. Its name was Sputnik, but it was later called Sputnik I so they could distinguish it from the other satellites that they would launch into space at a later time with the same name.
How fast in kilometers does the earth orbit the sun per hour?
That depends on where you are standing. At either pole, earth rotates once every 24 hours (as it does everywhere else), but you don't really move at all with respect to its center. We can do some rough calculations. Earth's diameter is roughly 8000 miles, making its circumference approximately 24 thousand miles (Ï€d). 24 thousand miles divided by 24 hours gives you 1000 miles per hour, or 1610 km per hour.
The actual rotational velocity varies a bit from day to day for a variety of reasons.
At the equator, that would be 40,000 km / 24 hours,
or about 1700 kilometers per hour.
What does it look like on Jupiter?
Jupiter, the largest planet in our solar system, has a cloudy and turbulent atmosphere with distinct bands of different colored clouds. The planet is known for its iconic Great Red Spot, a massive storm that has been raging for centuries. Jupiter also has a system of moons, with the four largest—Io, Europa, Ganymede, and Callisto—visible through binoculars or a small telescope.
Solar energy (energy released by the sun) has been around for as long as the sun has - an approximate of around 5 million years. In 1861, Angute Mouchout was the first person to convert solar power into energy, when he created a steam engine that ran entirely on solar power. Solar power is one of the only renewable sources on our planet, but is still very inefficient.
In general terms here is how the solar system came into being. An earlier incredibly massive star exploded into a supernova at the end of its life, leaving a huge cloud of gases and debris. Out of this cloud a section began to come together under the force of its own gravity. The gases that formed the sun gathered in the center, and an accretion disk of materials began swirling around it. The accretion disk is material that began falling toward the central mass but fell into a swirling or orbital pattern rather than falling to the center. This disk of gasses and other debris eventually formed the planets. Solar wind rushing out from the young sun pushed the lighter gases away from itself, and this is why the rocky planets are closer in and the gas giants are farther out.
The Sun was formed about 4.57 billion years ago when a hydrogen mhttp://wiki.answers.com/wiki/Molecular_cloud collapsed. When the hydrogen atoms got transformed into helium atoms, heat energy was released and all this resulted in the formation of a massive star; our Sun.
How can it snow when there is a high pressure system?
Snow can occur in a high pressure system when the air is cold enough for the precipitation to fall as snow before reaching the ground. In these situations, the high pressure usually brings clear skies and calm weather, allowing for the conditions to be favorable for snowfall.
What can diamonds be used for besides jewelry?
Diamonds are used in the jewelry industry. We see this all the time, and in any public place where women are about, many wear diamond rings. But gems are the minor use of the diamond. Most diamonds are used in cutting and abrasive operations. Industry depends on them. Diamond is the hardest naturally occurring substance, and it is used to cut and grind metals, stone, ceramics and other very hard things. This "behind the scenes" use of this amazing mineral is lumped under the heading industrial diamonds.
When periods of the moons rotation and revolution are equal what is it called?
It is called synchronous rotation when the rotation and orbit take the same amount of time.
How old is the universe according to the big bang theory?
The Big Bang theory doesn't actually say all that much about how old the Earth is. Obviously, if the Universe is 13 billion years old, the Earth can't be any older than that. Less obviously, the Big Bang produced mostly hydrogen and virtually no metals ("metal" is astronomical code for "anything heavier than helium"). Heavy elements were produced later, in stars, and released by supernova explosions. Since the Earth is made mainly of elements heavier than helium, it has to have formed after there was time for stars to form, age, and go supernova, and for the gas and dust produced to coalesce into the solar system. However, this only provides a maximum age, not a minimum; as far as the Big Bang theory is concerned the Earth could have formed last Tuesday. The generally accepted age for the Earth (4-5 billion years) is based on other factors, such as radioisotope ratios in rock.
The big bang theory has nothing to do with the age of the earth. Scientists think the earth is 4.4 billion years old. That is the age of the solar system. That is the age of some meteorites that have fallen to earth. Their age is determined by the ratio of uranium to lead. Uranium is radioactive and over the years becomes a special form of lead.
The big bang theory had to do with the age of the universe. Scientists determined the age of the oldest light in the universe and put some formulas into their equations to figure out how long ago it was created. They assumed it was created by the big bang. If their equations are correct, they know the age of the universe.
Over several years the apparent size of the sun as viewed by an observer on Earth will?
i believe the answer is it will vary in a cyclic manner because the earth moves farther away from the sun in summer in the northern hemisphere and then closer in the winter
How would you describe the bacteria kingdom?
The bacteria kingdom consists of unicellular prokaryotic organisms that have a simple cell structure without a nucleus. They are found in various environments including soil, water, and inside other organisms. Bacteria play important roles in nutrient cycling, decomposition, and maintaining ecosystem balance.
How do carbonized remains form?
Carbonized remains form when organic matter such as plants or animals are burned in a low-oxygen environment. The high heat and lack of oxygen cause the organic material to break down and leave behind a carbon residue. These carbonized remains can provide valuable information about past ecosystems and climate conditions.
How many miles does earth travel around the sun?
2654950 is not correct. The actual distance traveling along the equator would be 24,906 miles.
Which differences do the division of Earth's atmosphere into layers is based on?
not entirely sure what you're asking, but the earth's atmosphere is divided into sections base on the gases that compose of that section's density, with the most dense gases closest to earth and least dense furthest from earth's surface
What is the science behind the gravity of Earth?
There is a very easy analogy for how gravity works. Everything in the universe takes place within spacetime. Imagine spacetime as a trampoline. Where mass exists, spacetime becomes curved, just like a trampoline would become curved if one were to place a bowling ball on it. We as people fall down the curves made in spacetime, but the earth keeps us from falling any further, thus we are stuck to its surface. If one were to put a ping-pong ball on the trampoline, it would fall down the curve made by the bowling ball. It would stop once it hit the bowling ball, and be stuck to its surface. There are a few subtleties to this model that keep it from working perfectly, but this is basically how gravity works.
Earth gets most of its energy from this form of energy?
Earth gets most of its energy from the sun in the form of solar energy. Solar energy provides heat and light to Earth, driving various processes including weather patterns, photosynthesis, and the water cycle.
How far away from rhe sun does mars orbit?
Mars orbits the sun at an average distance of about 142 million miles (228 million kilometers). Its orbit is elliptical, so this distance can vary slightly depending on its position in the orbit.
Can you define altitude of a celestial body?
Altitude of a celestial body is the angular distance between the horizon and the body when viewed from a specific location on Earth. It is measured in degrees and ranges from 0° at the horizon to 90° at the zenith, directly overhead.
How long does a rainbow in the sky live?
Rainbows are caused by sunlight glinting off tiny water particles in the sky, bouncing the light back towards the observer. In other words, any time you see a rainbow directly in front of you, the Sun is directly behind you, and your shadow points at the center of the circle the rainbow is describing.
This can last as long as the droplets and the Sun are in the right position, which makes it dependent on the weather, partly, and weather lasts as long as it feels like lasting!
for as long as the suns out or as long as the sun is shining on the water
Does the moon wane until it appears to be a full moon?
Yes it does because it revolves around the sun
