What is a watershed?
200
This is created when magma or lava cools down.
What is igneous rock?
300
This is caused by transportation, industrialization, and agricultural waste becoming trapped in the atmosphere as air pollution.
What is climate change?
300
The further up you go in altitude, the less air density there is to hold in heat.
Why are mountains so cold at the top?
300
Forest floor, understory, canopy, emergent layer.
What are the layers of a forest?
300
They are formed by water getting pulled down by gravity into one spot.

400
Their process of formation is due to plate tectonics.
Why are mountains so high?
400
Chlorophyll causes this pigmentation.
Why are leaves green?
400

How does the water cycle happen?
400
This is what causes rock to change form.
What is erosion, pressure, and heat.
500
Thrust, lift, and air pressure creating an air cushion.
How do airplanes stay aloft?
500
This happens when there is not enough oxygen in the air, and the air is too thin.
What is altitude sickness?
500
The wind causes the trees to remain short and strong in this type of forest.
What is a dwarf rainforest?
500
Runoff of industrial chemicals and other types of ground pollution into the water, as well as air pollution coming down with precipitation, causes this problem.
How does water pollution happen?
500
This is what the layers of the Earth are made from.
What is: rocks and soil (crust); magma (mantle); hotter magma and liquid metal (inner core); solid iron and nickle (inner core)
