Question 1: Approximately how much of the Earth’s surface is covered in water?
We know from science that about
70% of Earth’s surface is covered by water — mostly oceans, but also lakes, rivers, and ice.
The options are: 85%, 70%, 50%.
✔ Correct answer:
70%

Question 2: Hail, snow, rain and sleet are all types of what?
These are all forms of water falling from clouds to the ground. That’s called
precipitation.
Evaporation is when water turns into vapor (goes up). Transpiration is when plants release water vapor.
✔ Correct answer:
precipitation

Question 3: What is water that is underground called?

Question 4: What is the name for the process of water turning from a liquid to a gas in the air?
When liquid water becomes invisible water vapor (gas) and goes into the air — like puddles drying up — that’s
evaporation.
Precipitation is falling water. Condensation is when gas turns back to liquid (like dew).
✔ Correct answer:
evaporation

Final Answer:
1. 70%
2. precipitation
3. groundwater
4. evaporation
