Astrobiologists use a variety of tools such as microscopes, spectrometers, telescopes, and rovers to study the possibility of life beyond Earth. They also utilize molecular biology techniques to analyze samples collected from space missions or extreme environments on Earth. Additionally, astrobiologists rely on computer modeling and simulations to understand how life could thrive in different environments.

Yes, if he did not study anything beyond the Earth, he would not be an astronomer!

The branch of Earth Science that studies objects beyond the Earth's atmosphere is astronomy. It is the study of the sun, planets, stars, galaxies, and the universe.
I believe It's the earths mantle. But I'm not 100% positive!
The answer depends on the context: Do you want: frozen water as a percentage of all water on earth? frozen water as a percentage of all matter on earth? frozen water as a percentage of all water in the solar system, or beyond? frozen water as a percentage of all matter in the solar system, or beyond? There are other possible interpretations.
71% is water 29% is land
This depends on what you mean with 'human use'. But it is estimated that 2.75 percent of all water on Earth is fresh water (which I believe is what you mean). Most of that however (2.05) is frozen in glaciers. A further 0.68 percent is ground water, with only 0.011 percent being surface water (in lakes and rivers).
The Earth's atmosphere gets thinner and thinner as we go away from the earth. It becomes negligible at a point in space. Beyond that, there is no atmosphere, only vaccum.
