What is the difference between stars and shooting stars?
First off, shooting stars aren`t actually stars. They`re actually pieces of space rock called meteors. When meteors enter Earth`s atmosphere, they burn up, producing bright lights as they move through the sky. That is, if it`s night. If it`s day, then you can`t see them light up. Meteors are so fast that people say they`re faster than a speeding bullet, hence the name ''shooting'' star.
Why is the moons surface more heavily cratered than the earths surface?
A Biblical answer from Genesis 1 would be that in the beginning the Earth was covered with water. During creation week this water was separated into areas on the Earth and above the Earth. Like seas/lakes below and a "giant peel" of water above somewhere in the stratosphere. Any Meteors impacting the earth at first would fall in water, later go through the "peel of water". So only after the Flood Meteors that survived the Atmosphere would hit the Earth and leave a crater, hence less craters on Earth.
Are meteors on fire?
Meteorites travel at exceedingly high speeds relative to the Earth. When they encounter our atmosphere, they are travelling so fast that the friction of the air heats them very quickly into the thousands of degrees. They don't "catch fire" in the normal sense that you and I speak of -- instead they are heated to incandescence, similar to the way that electrical current causes a light-bulb filament to glow.
What was the first thing to go to space?
It has been hypothesized that the "first" object from earth the exit the atmosphere and enter space was in fact the moon. However, the first documented man-made object to enter orbit was the Soviet satellite Sputnik, in 1957.
Why is the earths surface not covered by the same impact craters?
First, we have a nice thick atmosphere that deals with many meteors. Secondly, weathering and erosion erase the marks fairly quickly.
Why don't meteors first burn up when they first enter earths atmosphere?
It takes a while for air friction to heat them through. Also some are massive enough that they never burn up but hit the earth instead, becoming what we call meteorites.
What layer of atmosphere where meteors burn up while entering the earth?
Meteors start to glow in the Mesosphere, and usually burn out in the upper Stratosphere. Put another way, when you first see a meteor, it is about 80 miles up, and when it "goes out" it is about 40 miles up.
What was the first time that meteors hit earth this year?
January 1st.
Who is the first particle enter the earth at first time?
The first particles to come to Earth were likely dust and debris left over from the formation of the solar system about 4.6 billion years ago. These particles gradually came together to form the Earth and its early atmosphere.
Why are meteorite non luminous?
The high speed that meteors travel through the atmosphere results in friction that causes them to become luminous. They become hot enough to burn and glow and their speed, mass, and size are factors that determine their luminosity.
Who were the first people that die on the moon?
Nobody has ever died on the moon, or even in Earth orbit (although some have died while attempting to enter or exit Earth's atmosphere)
Is the stratosphere above the troposhere?
Yes. The troposhere is the first layer of the atmosphere.Then the stratoshere(where the ozone layer is located).Next is the mesosphere,where meteors that enter the atmosphere burn up. Then there is the thermosphere.After the thermosphere there is the exosphere, and the last layer(which is very thin)is the magnetosphere. It is earth's magnetic field. It also causes the northern lights! Hope this novel helped.

Why do meteors light up or burn when seen in the night sky?
Meteors are space debris made of rock or metal. When they enter the Earths atmosphere they heat up through friction with the air and glow very brightly. They can be seen streaking across the sky and seem to be on fire. Hence the name fireball.
Earth can be divided into how many physical layers?
The http://wiki.answers.com/earth/Atmosphere/overview.htmlis divided into five layers. It is thickest near the surface and thins out with height until it eventually merges with space.1) The http://wiki.answers.com/earth/Atmosphere/troposphere.htmlis the first layer above the surface and contains half of the Earth's atmosphere. http://wiki.answers.com/earth/Atmosphere/weather.htmloccurs in this layer.2) Many jet aircrafts fly in the http://wiki.answers.com/earth/Atmosphere/stratosphere.htmlbecause it is very stable. Also, the ozone layer absorbs harmful rays from the Sun.3) Meteors or rock fragments burn up in the http://wiki.answers.com/earth/Atmosphere/mesosphere.html.4) The http://wiki.answers.com/earth/Atmosphere/thermosphere.htmlis a layer with auroras. It is also where the space shuttle orbits.5) The atmosphere merges into space in the extremely thin http://wiki.answers.com/earth/Atmosphere/exosphere.html. This is the upper limit of our atmosphere.
When did water first come on earth?
This is a well-debated question, and there is no certain answer yet. Many scientists believe that the first water came to Earth in its primitive stages. They think that meteors brought molecules of hydrogen and oxygen in the form of ice. Then, as the Earth heated, this turned to steam, and went through the first hydrological cycle. Later, as the earth's surface cooled and the atmosphere cleared up the steam changed to its liquid form.
When was the first atmosphere?
The idea to when first atmosphere was made is difficult. The atmosphere is present from the beginning. This allowed human life on earth.
