1)The point under the ground where an earthquake begins.

Focus
The point above the point on the surface of earth is known as Epicenter and the places near it are the most affected.

2) The process of adding chlorine to water to kill germs.

Chlorination
This process is mainly used for the purification of water in large amount as well as in the home water filter $.$

3)The deep holes on the surface of the moon.

Craters
They are cracks formed by the hitting of meterioites and asteroids on the surface of moon.

4)The layer of the atmosphere in which spacecraft orbit.

Thermosphere & Exosphere.
Depends on the space shuttles, spacecrafts and the motive behind sending them to space.

5)The process by which salt can be separated from water.

Evaporation, then crystallization
Salt is a non-volatile solid which remains behind when water is evaporated. Later it is crystallized to get pure form of salt.

6)The types of tide in which the water level rises.

High tides.
They are due to the gravity of moon upon earth. The difference in height between the high tide and the low tide is called the tidal range.

Answer:

In moon there are some mountain which are bigger than Mt. Everest.
Focus is the place where the earthquake begins. And it is measured by Richter Scale.
In Earth's atmosphere there are five layers. In the fourth one the spacecraft orbit named, Thermosphere.
For making pure water from sea water at first we evaporates the water and then we do crystallization.
