The four agents of Erosion.

Water, Wind, Glaciers, Gravity

100

The layer of the atmosphere in which we live

Troposphere 

100

The layer of the Earth that we live on.

The Crust

100

The three types of rivers

Old, Young, Mature

100

CFC stands for this.

Chlorofluorocarbon 

200

This agent of erosion is the most effective.

Running Water

200

These two layers of the atmosphere increase in temperature with altitude.

Stratosphere + Thermosphere

200

The two elements that make up the core.

Iron and Nickle

200

Name given to the large turns and curves in a river.

Meanders 

200

The chemical compound makeup of Ozone is this.

O3
300

Sediments that are separated by size with the largest on the bottom and smallest on the top.

Vertical Sorting

300

This layer of the atmosphere is where meteoroids and other space debris burns up.

Mesosphere

300
Rock that makes up the continental crust, has large crystals.

Granite 

300

Type of river that is rather steep, fast, and has a straight valley.

Young River

300

The Asthenosphere is about this thick in kilometers. 

3000 km

400

The two factors of Carrying Power

Speed and Discharge

400

The stratosphere contains this, which protects us from harmful rays from the sun.

Ozone Layer

400

Behaves like a thick liquid, molten metal.

Outer Core

400

The Ohio River and upper portions of the Mississippi River are examples of these types of Rivers

Mature River
400

This continent is the smallest continent. 

Australia

500

Term given to the use of sand, pebbles, and boulders as cutting tools. During this process the "tools" wear down.

Abrasion

500

The thermosphere is made up of these two mini-layers.

Ionosphere + Exosphere

500

Caused by the inner core spinning within the outer core.

Magnetic Field

500

Small stream that runs along a river and joins said river eventually.

Yazoo Stream

500

Oxygen. Silicon. Aluminum. Calcium. Iron. Sodium. Magnesium. All of these elements make up the crust, and this element is missing from the list.

Potassium
