What is the classification of about 90 percent of the stars?
About 90 percent of stars are classified as main sequence stars, which means they are in the stable phase of their lifecycle where they are fusing hydrogen into helium in their cores. These stars follow a pattern on the Hertzsprung-Russell diagram known as the main sequence.
What are the two most common elements found in the Earth's continental crust?
The two most common elements found in the Earth's continental crust are oxygen and silicon. Oxygen is the most abundant element, making up about 46.6% of the Earth's crust by weight, while silicon is the second most abundant, making up about 27.7%.
I am a digital assistant and do not belong to a physical planet.
I believe trough is high tide but I'm not 100% sure
A trough is the low part of a wave, the opposite of crest.
What does it mean if a star has similar size and surface to the sun?
If a star has a similar size and surface to the sun, it means that it is likely a main sequence star like our sun. These stars go through nuclear fusion to generate energy and typically have a stable lifespan of billions of years. They are often classified as G-type stars.
Why is japan's geography bad for natural disasters?
Japan is located on the Pacific Ring of Fire, making it prone to earthquakes, tsunamis, and volcanic eruptions. The country's mountainous terrain and proximity to ocean trenches contribute to the severity of natural disasters. Additionally, Japan experiences typhoons and heavy rainfall, which can lead to landslides and flooding.
What family does liver fluke belong to?
The Liver Fluke is a parasite, I believe it is the misqito family, but do not quote me on it.
Name the science that studies the space bodies?
Astronomy is the science that studies space bodies like planets, stars, galaxies, and other celestial objects. It observes the positions, motions, and properties of these objects to understand their behavior and composition.
How does the sun obtain its energy?
The sun obtains its energy through nuclear fusion, a process where hydrogen atoms in its core combine to form helium, releasing a tremendous amount of energy in the form of light and heat. This process is sustained by the sun's immense gravity compressing its core and maintaining the high temperatures and pressures needed for fusion to occur.
Which orders contain the elephants rabbits and horses?
Elephants-Proboscidea
Rabbits-Lagomorpha
Horses-Perissodactyla
Would human extinction solve the worlds pain?
yes because it will cause no more pollution and decrease the destruction of nature.
___________
No, that's silly. The earth is in fact feeling no pain. Humans are simply speeding up what are perfectly natural cycles on earth. The earth has gone through stages much more toxic than the present, and it will again. As we speed the cycles up, we are only hastening our own destruction, nothing more. The earth will go on following its natural cycles and will neither miss us nor be grateful for our passing.
Pegasi are mythical creatures and their alignment as good or evil is subjective and can vary depending on the context or story being told. In general, pegasi are often portrayed as noble and benevolent creatures in mythology and fantasy literature.
Chicks can hatch at any time of day or night, as they follow their natural instinct to break free from the egg when they are ready. The process can take several hours, but it is not uncommon for hatching to occur during the night.
Can the starfish move from place to place by themselves?
0.5/1.0 miles per hour they are the fish fastestinthe ocean the sunfish is the best swimmers of allthe fishes in the world
What is earth moving equipment?
Earth moving equipment includes machinery used for digging, moving, and shaping the earth's surface, such as excavators, bulldozers, and loaders. These machines are commonly used in construction, mining, and infrastructure projects to clear land, excavate foundations, and transport materials.
What are 3 ways that snow accumulates on earth?
Snow accumulates on Earth through precipitation, where snowflakes form in cold clouds and fall to the ground. It can also accumulate through snowdrifts, where wind blows snow into piles or banks. Additionally, snow can accumulate through snowfall that gradually builds up over time during winter months.
What does Earths' revolution around the sun cause?
The increment of one calendar and solar year per revolution (by definition), the changing pattern of different stars and constellations, and, to an extent, planets visible from the night side of Earth, tidal effects, and tiny gravitational perturbations of the Sun and nearby planets' positions. Very tiny.
The Earth's revolution around the Sun does not, by itself, cause the changing seasons. That is a common misconception. The Earth's polar spin axis is not exactly perpendicular to its orbital plane. It is tilted. This accounts for the seasons far more than revolving around the Sun, although neither would work without the other.
Can you lose an arm from a wasp sting?
Not as a rule! While it is theoretically possible, the likelyhood of this happening is low. Some people are highly allergic to insect stings & bites, although this is relatively uncommon. In most of the worst cases patients treated in good time make full recoveries. Very young infants and elderly people who display allergic reactions are particularly vulnerable to the more serious effects. Some possible effects of a sting for those who are severely alergic include localised or widespread rashes & itching / redness & swelling (a small amount of swelling is normal), hyperventilation, involuntary twitching / spasms, seisures, headaches & nausia, vomiting, sensory halucination, vertigo / disorientation, brief unconsciousness, heart attack, stroke, coma or ultimately death. I remember hearing this myself at school when I was about 6. Children are great at scaremongering and love to try to frighten each other. Whats worse is that they succeed sometimes! What you ask IS possible, but it is very unlikely. Most people dont have anything to worry about! If you're not sure if you might be allergic, or are worried that you might be showing symptoms of an allergy it is always best to consult your own doctor. Its also a good idea not to play with wasps... especially ones that are the size of small birds (those ones are usually Hornets. Hornet sting = pure, unadulterated pain & a rapid trip to hospital if you're smart!)
What is released when decomposers break down the remains of other organisms?
when organism is dead decomposers start to work, they cause the dead tissue to decompose. They break down carbon containing molecules and CO2 is released. Also Bacteria and fungi break organic matter down into inorganic substances. Dead plants, animals, manure-Ammonification-NH4+-Nitrification (NO3-)-Leaching (water soluble), Some bacteria in the soil use nitrate (NO3−) rather than oxygen for cellular respiration, they convert it into nitrite that's released into the soil or nitrogen gas that's released into the atmosphere.
Why does Antarctica have longer days in the summer?
Antarctica experiences longer days in the summer due to its position near the South Pole. During the summer months, Antarctica is tilted towards the sun, causing the sun to stay above the horizon for longer periods of time. This phenomenon, known as the midnight sun, results in continuous daylight for several months.
Write them in order from the center to the outside of the planet?
- Inner core: Solid iron and nickel with extremely high temperatures and pressures.
- Outer core: Molten iron and nickel that generates Earth's magnetic field.
- Mantle: Rocky layer composed of silicate minerals that convects to drive plate tectonics.
- Crust: Thin, solid outer layer where we live, made of lighter silicate rocks.
Does the sun make its own food?
No. Plants "make their own food" using sunlight. The sun is not alive so there is no food for the sun.
Tidal Forces? I think what you mean to say is centrifical force. Slowing down the rotation would allow gravity to effect us more drawing us in. Centrifical force ensures we stay at the farthest point allowed by gravity.

Here's a more elaborate answer from New Scientist:
Russian dynamicists Gregoriy A. Krasinsky and Victor A. Brumberg calculated in 2004, that the sun and Earth are gradually moving apart. It's not much - just 15 cm per year - but since that's 100 times greater than the measurement error, something must really be pushing Earth outward. But what? One idea is that the Sun is losing enough mass, via fusion and the solar wind, to gradually be losing its gravitational grip (see Astronomical unit may need to be redefined). Other possible explanations include a change in the gravitational constant G, the effects of cosmic expansion, and even the influence of dark matter. None have proved satisfactory. But Takaho Miura of Hirosaki University in Japan and three colleagues think they have the answer. In an article submitted to the European journal Astronomy & Astrophysics, they argue that the sun and Earth are literally pushing each other away due to their tidal interaction. It's the same process that's gradually driving the moon's orbit outward: Tides raised by the moon in our oceans are gradually transferring Earth's rotational energy to lunar motion. As a consequence, each year the moon's orbit expands by about 4 cm and Earth's rotation slows by 0.000017 second. Likewise, Miura's team assumes that our planet's mass is raising a tiny but sustained tidal bulge in the sun. They calculate that, thanks to Earth, the sun's rotation rate is slowing by 3 milliseconds per century (0.00003 second per year). According to their explanation, the distance between the Earth and sun is growing because the sun is losing its angular momentum.

Ofcourse it is.. for two reasons:-\
1) The Sun is losing mass
2) The Tidal Interaction Slows The Sun's rotation.
What person did the most to prove the earth was shaped like a ball?
Columbus did the most to prove the earth was shaped like a ball. He did this by sailing to America, and proving to Europe that the world was not flat.
Edit: a lot of people think that, but it was established by the Ancient Greeks
about 1800 years earlier.
