What usually burn up the Earth's atmosphere?

Meteors and other objects entering Earth's atmosphere burn up due to friction with air molecules at high speeds, creating heat and light. This process is known as atmospheric entry or ablation.


What causes seismic waves to change speeds as they move through earths layers?

Seismic waves change speeds as they move through Earth's layers due to differences in the physical properties of the materials in each layer. Factors such as density, rigidity, and composition of the rock can affect how fast seismic waves travel through them. The waves can speed up, slow down, or change direction as they encounter different materials with varying properties.


What are examples on how the atmosphere affects the hydrosphere?

The atmosphere affects the hydrosphere through processes such as evaporation, precipitation, and wind. For example, when the atmosphere is warmer, it speeds up the process of evaporation from water bodies. Wind can also cause waves on the surface of oceans and lakes, influencing water currents and patterns. Additionally, the atmosphere can carry pollutants that can contaminate water sources through precipitation.


How much slower does a meteorite go when it hits the earth's atmosphere?

A meteorite can enter Earth's atmosphere at speeds ranging from 25,000 to 160,000 miles per hour. The drag and friction from the atmosphere slow it down and cause it to heat up, often resulting in a bright streak of light known as a meteor or shooting star.


Which layer of the atmosphere burns up meteroids?

Meteors burn up in the mesosphere as they encounter resistance from air molecules at high speeds, resulting in friction and heat that vaporize the meteoroid.

What do scientists call a rock that strikes earth's surface?

Meteorites. When floating in space they are called meteoroids, they are then called meteors when they enter the earths atmosphere at high speeds, burning up brightly as shooting stars for a brief period due to the friction against the gas in the atmosphere. If any surviving pieces are found on the surface, they are called meteorites.


Pieces of rock that strike the surface of a moon or planet?

These are meteoroids, small pieces of rock debris in space. They enter the earths atmosphere at high speeds, burning up brightly as shooting stars for a brief period due to the friction against the gas in the atmosphere - at this point they are referred to as meteors. If any surviving pieces are found on the surface, they are called meteorites. Since the moon has no atmosphere, meteoroids are able to survive the decent more easily, since there is no gas to cause them to burn up through friction.


Where would a satellite revolving around earth land if it crashed?

It will most likely burn up through the earths atmosphere on re-entry. The satellites travel at very high speeds, and are not designed to withstand the brunt of the earths atmosphere at the speeds at which they orbit the earth. You might get some bits left over, but these should be quite small. Operators try to land the satellite in the sea once it has reached the end of its life.


Where would you most likely find a meteor?

Meteors are pieces of rock glowing hot in the atmosphere. Before they hit the air, they were meteoroids. When they his the ground they are meteorites. Meteors are only found in the atmosphere, moving at incredible speeds.


Why does a space shuttle need to travel so fast when entering earths atmosphere?

Although it reaches incredible speeds, a Space Shuttle is not going fast when it enters the atmosphere. The gravitational pull of Earth, or just gravity, are pulling down on the space shuttle with immense force.


What are the average wind speeds on mercury?

There are no wind speeds to discuss on Mercury, since there is no atmosphere there.


Wind speeds on mercury?

There is no wind because Mercury has no significant atmosphere.


Are falling stars just a myth?

No. Falling stars do exist, but they are not actually stars. Meteors, as they are properly called, are small pieces of rock falling from space. As they hit the atmosphere at extreme speeds they heat up and produce a streak of light before being vaporized. The actual stars are much larger and much farther away.


What are things that burn up in Earths atmosph ere?

Objects like meteors, spacecraft upon re-entry, and volatile gases can burn up in Earth's atmosphere due to the intense heat and friction produced as they travel through the air at high speeds.


How fast does a space shuttle travel in earths atmosphere?

A space shuttle reentering Earth's atmosphere travels at speeds around 17,500 miles per hour. This high speed generates intense heat due to friction with the air, causing the iconic glowing plasma trail behind the shuttle.


What factors would be necessary to achieve greater speeds for a space shuttle while completely out of the earths orbit and in space?

Once out of the atmosphere, the only question would be fuel. The shuttle empties the external tank during liftoff. It is essentially out of fuel at that point. If it were refueled, it could continue to accelerate.


What are small rocks that enter the earth's atmosphere at speeds of 15 to 70 kilometers per second and burn up?

The small rocks that enter the Earth's atmosphere at high speeds of 15 to 70 kilometers per second and burn up due to friction and heat are called meteoroids. When they burn up in the atmosphere, they create bright streaks of light known as meteors or shooting stars.
