Earth Sciences

The Sun's high temperatures and pressures prevent the existence of liquid water on its surface. Temperatures on the Sun can reach millions of degrees Celsius, far higher than the boiling point of water. Any liquid would instantly vaporize under these extreme conditions.

The characteristic of being able to reflect light is called albedo. Substances with high albedo are able to reflect more light. The major substances with high albedo that reflect light back into space from Earth are: clouds, snow, ice caps, aerosols etc. In fact, many environmentalists are pushing the "White Roof Movement" that encourages the painting of roofs white in order to increase the albedo in urban areas, hopefully decreasing the urban heat island effect.

On average, Japan experiences around 20% of the world's earthquakes of magnitude 6.0 or greater on the Richter scale, which can trigger tsunamis. However, actual tsunamis hitting the Japanese coast can vary from year to year depending on seismic activity. The Japan Meteorological Agency issues warnings whenever a tsunami is detected.

The Moon's surface is heavily cratered because of of meteor impacts. Meteors are able to more commonly strike the Moon's surface than the Earth's surface because the Moon's atmosphere is not as strong as the Earth's, so less meteors burn up in the Moon's atmosphere than they do in the Earth's atmospheres. So the craters are simply the result of heavy meteor impacts.

Answer #2

The moon has no weather to erode craters. Speculation is that the earth has been hit at least as many times as the moon because of our greater mass. Wind, water, and plate tectonics wipe out the evidence on earth.

The sun is only visible during the day because it is blocked by the Earth at night. When the Earth rotates on its axis, the sun is obscured from view as the part of the Earth you are on turns away from it.

It is impossible to actually "defy" gravity. Even the Voyager spacecraft at over four billion miles from the earth experience some gravity from the earth. Satellites can orbit the earth at as low as 220 miles or less. They still fall toward the earth, but their forward speed carries them at an arc that matches the earth's surface.

Errors in measuring accuracy of waistline include measuring at the wrong location on the waist, not keeping the tape measure parallel to the ground, inconsistent tension when measuring, and not measuring at the same time each day for consistency.

Some creationists use this argument as "evidence" against evolution.

However, the flaw in their argument is that fossils do occur, they are in order, they are separated by a large time difference, and they are transitional.

The argument is commonly called the "missing link" problem, and when Darwin first developed his ideas, it actually was. He explicitly recognised it as such, and came up with several ways it would either deny or help support his theory (such as by finding rabbits in the PreCambrian era, or by the presence of missing links, which were later found). However, in the 140 years since then, we have uncovered thousands of fossilized species, each of which is a tranistional form in the evolution of several other species.

The best example is that of our own ancestry; several species have been discovered, each getting closer and closer to human as we know it, and at the same time, further from the simple ape-like mammals we began as. All of this happened - according to the geological timeframe - over a period of several million years.

Space does not have a significant atmosphere like Earth. While there are small amounts of gases and particles in space, the pressure is extremely low compared to Earth's atmosphere. Satellites and astronauts must rely on artificial life support systems to survive in the vacuum of space.

Yes, in the Intertropical Convergence Zone (ITCZ), air from the subtropical high-pressure zones converges and rises due to the Earth's rotation and the warm temperatures at the equator. This rising air leads to the formation of clouds and heavy rainfall in the region.

Glacial drift is the term for all sediments of glacier origin.

if by combine you mean two stars crash into each other, the average sized star would melt into the red giant, if by combine you mean place the average inside the red giant, the averagesize will just expand and be absorbed

No, a flea is not the fastest animal on earth. The peregrine falcon holds the title of fastest animal, reaching speeds of over 240 miles per hour when diving to catch prey.

The ground motion produced by a P-wave is a rapid back-and-forth motion in the direction of wave propagation, causing particles to compress and expand. In contrast, surface waves cause horizontal shaking and rolling motion along the surface, resulting in larger amplitudes and longer durations compared to P-waves.

The moon's surface gets smooth through various processes such as impact cratering, volcanic activity, and erosion by micrometeorites. Over time, these processes help to reduce surface roughness and create smoother areas on the moon's surface.

Mercury, Venus, Earth, and Mars are terrestrial planets, characterized by their solid, rocky surface. Jupiter, Saturn, Uranus, and Neptune are gaseous planets, composed mostly of gas and lacking a solid surface.

As a star runs out of fuel and starts to die, its outer layers expand and are pushed away by the strong radiation pressure from the core. This forms a glowing shell of gas called a planetary nebula. Eventually, the core collapses into a white dwarf, while the expelled gas dissipates into space.

The Sun volume is about 1,418,364,847.22 billion cubic km, Jupiter is 1,530,600.9 billion cubic km = 926 Jupiters.

A huge amount. As a rough comparison: Main sequence size a beach ball, white dwarf size a marble. The white dwarf, though is millions of times denser than it's main sequence parent.

The time the sun sets in the summer varies depending on your location. Generally, in the summer months, the sun sets later in the evening compared to winter months, allowing for longer daylight hours. You can check a local weather website or app for the specific sunset time in your area.

Yes, the rotation of the Earth on its axis causes day and night. As the Earth rotates, different parts of the planet are exposed to the Sun's light, creating daylight in those regions and darkness in others.

There are 3 main waves types associated with earthquakes. P(primary), S (secondary and T (tertiary). Both P and S waves are body waves and occur rather quickly. Tertiary waves are waves that are slower than P and S and are recorded in the SOFAR regions of the ocean and occur due to multiple reflections of the wave between the sea floor and sea surface.

The Onondaga credit the Sky Woman, also known as Atahensic, with bringing Earth into existence. She fell from the sky world and landed on the back of a giant turtle, which grew into the land that became Earth.

Sunset occurs during the transition from day to night. It is the time when the sun goes below the horizon, leading to a decrease in light and the beginning of twilight.
