How many states can we find water in?
What is the melting also known as- Solid to liquid?
Water can be found in three states- solid, liquid and gas.
Melting can also be called fusion.

Define percolation. What is a water table and what are aquifers?
Percolation is the process of surface runoff water getting absorbed into the ground. The topmost layer of the water underground is known as the water table. The rocks and stones directly below the water table that are saturated by water are known as the aquifers.

State of going solid to a gas and vice versa?
Solid to gas- Sublimation
Gas to solid- Deposition

Define the greenhouse effect in your own words. What is making the greenhouse effect worse?
Greenhouse effect is heat getting trapped in the Earth's ozone layer and not being able to escape into space. This is in turn heating up the Earth and is continuously being causes by air pollution (cars, factories, smoke from wildfires, etc.).
