What are space objects that burn as they enter Earth's atmosphere called?
Its called friction. When the rock enters the atmosphere it can be travelling at thousands of miles and hour. In space there is nothing to slow it down, when it comes to the Earths atmosphere there is resistance as the air tries to slow it down, this creates heat and the tempretures can reach thousands of degrees, rock melts at about 1200ºC.
When fog and smoke form together in the atmosphere they become?
Smog
Why does the air become less dense as the altitude increases?
Because there is less air above, pushing down.
What would happen if a hot air balloon rose higher and higher in the atmosphere?
After you hit a certain altitude, the air would become so thin, it would starve the flame making the balloon rise of oxygen, the flame would go out, and the balloon would come plummeting back down to earth
Why doesn't meteor hit the Earth's surface?
Yes, they do. Just this week (January 18, 2010) a meteor crashed through the roof of a doctor's office in Virginia and landed on the floor of the examining room. Granted, MOST meteors burn up in the atmosphere and don't survive the passage. But some do.
What do meteors become when they enter the Earths atmosphere?
Hot
What happens to the air pressures as altitude increases?
As altitude increases, air pressure decreases. Gravity causes the atmosphere to become heavier the closer you are to the ground. The atmosphere may seem weightless but all the air molecules add up to a tremendous amount of mass. If you think of the atmosphere like blankets, the more blankets you have piled on you the heavier they become, thus pressing down on your body more and more. This is the same in the atmosphere, where the higher the altitude, the less overlying atmosphere, the less pressure on air molecules. At higher altitudes the air molecules have more freedom to move around.
Is there ice in the atmosphere?
no but you have to answer to your teacher. Edit : Yes, there is a small amount of ice in the Earth's atmosphere in the form of high altitude clouds. It's cold enough for water to become little ice crystals.
What demonstrates the temperature of a layer of the atmosphere?
The way the layer interacts with solar radiation.
How did the earths atmosphere change composition to become todays nitrogen and oxygen atmosphere?
your question is... How did the Earth`s atmosphere change composotion to became today`s nitrogen and oxygen atmosphere? Answer: it happend with the help of solar untraviolet (uv) radiation,the very thing what we worry about now for its cancer-causing ability
Why planets and moons appear to look shiny?
because they reflect the suns light, so they become visible to us. they twinkle due to the earths atmosphere blocking out some of the light.

How do solid particles become part of earths atmosphere?
Solid particles such as dust get into the air when wind picks them up and carries them. Other particles such as salt are picked up by ocean spray.
How does increasing attitude affect air pressure and density?
as the altitude increase, the effect of gravity become more insignificant on air and the air become more disperse or thinner hence it does affect the air pressure and density by decreasing both air pressure and density of the air.
What causes a spaceship to get hot when reentering earths atmosphere?
The heat generated by friction due to 'rubbing' against the air at re-entry speed. This is the same effect that causes a stone or a grain of sand to burn when it enters the atmosphere and become visible as a 'shooting star'.
What Are rocky objects orbiting the solar system that might enter earths atmosphere?
Asteroids are the rocky planet remnants orbiting the solar system in the asteroid belt. Collisions between these objects may leave debris that can enter the Earth's atmosphere and become meteorites.
Why does atmosphere become less dense as the altitude increases?
The atmosphere becomes less dense as altitude increases because there is less weight on the air molecules,making them less compressed. The air at a low altitude is denser because it is pressed down by all of the weight of all the air molecules above it.
