Answer:
Base on earth's structure, process and geologic history.
Explanation:
There are various planets in outer space that are considered analogous to that of earth or the Earth-like the planet like <u>Kepler-22b. Kepler-69c. Kepler-62f and Kepler-452b</u>. These Earth-like planets are called as G and K stars. like venus which is considered a twin of earth. These planets are considered to be 50% like earth but differ based on temperature and Terraforming is going to be what might be influencing the future of the explorations. Which is a hypothetical process of deliberating modifying the atmospheric conditions to make it habitable for man.
Answer:
e. is produced by the absorption of UV radiation.
Explanation:
The thermosphere is a layer of Earth's atmosphere which is directly above the mesosphere and below the exosphere. It extends from about 85 to 500 km altitude above the earth.
In the thermosphere, the temperature is strongly dependent on the level of solar activity. When the Sun is very active and emitting more high energy radiation, the thermosphere becomes hotter by X-ray and UV radiation absorption.
Dont post quiz questions, that is called cheating
Answer:
53.2%
Explanation:
- Write the mass of the elements in your molecule:
Mass of Si in 1 mol SiO2 =28.1g
Mass of O in 1 mol SiO2 =16x2g= 32g
- Now find the mass of your compound
Mass of compound= 28.1+32=60.1
- Divide each element's mass by the mass of the compound to find the percent by mass following this formula:
% by mass = (mass of element/mass of compound) x 100
% by mass of oxigen= (32g/60.1) x 100
% by mass of oxigen= 53.2%
I hope you find this information useful and interesting! Good luck!
