Why was earth able to hang on its atmosphere?
Gravity generally keeps it in place.
The Earth's atmosphere extends about how many miles above the earth's surface?
It extends about 75 miles. Earth's Atmosphere The Earth is surrounded by a blanket of air, which we call the atmosphere. It reaches over 560 kilometers (348 miles) from the surface of the Earth, so we are only able to see what occurs fairly close to the ground. Early attempts at studying the nature of the atmosphere used clues from the weather, the beautiful multi-colored sunsets and sunrises, and the twinkling of stars. With the use of sensitive instruments from space, we are able to get a better view of the functioning of our atmosphere.
How would the earth be different without the atmosphere?
The Earth wouldn't be able to support human life, it would be really hot because of the sun's UV rays, meteoroids would hit the planet, and the water we have today wouldn't be liquid, it would be solid.
Why do gases surround the Earth?
Gravity is able to keep the heavier gases close to the Earth's surface, but light gases such as helium rise in the atmosphere and are swept away by the Solar Wind.
Are geologists able to drill to the center of earth?
No they arent able to because earths inner core is to hot for them to drill!
Why are temeratures of earth and moon so different?
Because the moon has an incredibly small atmosphere, if it has any that is. The earth has a very big atmosphere compared to the moon. Thanks to all the CO2 in the atmosphere of earth, we are able to retain a really large amount of heat, unlike the incredible lack of any gas on the moon.
How planet earth was able to maintain a very comprehensive atmosphere?
Because it has sufficient gravity and a strong magnetosphere.
Why was mercury able to retain its atmosphere during its formation?
Mercury has a high surface temperature and a low mass
Why wasn't the Apollo lander able to land on earth?
Because it didn't have a heat shield. It burned up when it re-entered earth's atmosphere.
Why would an X-ray telescope based on Earth not be able to detect X-Rays emitted distant stars?
blocked by the Earths atmosphere but can be detected by telescopes placed in orbit round the Earth
Why the planet earth was able to maintain its atmosphere?
Gravity
The earliest atmosphere that Earth was able to hold on to was most like?
It would be the MOON because Consequently, earth's first atmosphere, was shallow and sparse, composed of lightweight hydrogen(h2) and helium (he) gases. Its atmosphere and climate would have been similar to that of our moon.
Why was earth able to hang on its atmosphere?
Gravity generally keeps it in place.
Scientists are able to deduce the Earth's shape based upon its what?
atmosphere.
If you can travel to a planet with an atmosphere like that of early earth would you be able to survive?
no
What would happen if there was no atmosphere on earth?
they would not be able to sustain human life.
Why is wave with longer wavelength able to travel further?
It is because longer wavelength wave is diffracted by the earth's atmosphere and so can 'cling' to the surface of the earth, whereas shortwave just goes out into space.
