100

The building of homes and roads is know as this.

What is human impact?

100

This process of the water cycle is caused by gravity.

What is precipitation?

100

Rivers are usually found at these elevations on topographic maps.

What are lower elevations?

100

This is the process that is like a "broom" and removes sediments that are created. 

What is erosion?

100

This type of mechanical weathering is caused by rocks bumping up against each other.

What is abrasion?

200

pH levels are measured in water to detect this.

What is acidity?

200

This is where most of the water on Earth is stored.

What is the ocean?

200

Close lines on a topographic map represent this. 

What is the steepness of elevation?

200

These create erosion along coastlines.

What are waves?

200

This type of chemical weathering is common in precipitation.

What is acid rain?

300

Farming puts too many of these into the water, creating dead zones.

What are nutrients?

300
This process of the water cycle is caused by the Sun.

What is evaporation?

300

Contour lines show this on a topographic map.

What is elevation?

300

These are created at the mouths of rivers due to erosion and deposition.

What is a delta?

300

This type of mechanical weathering is due to water freezing and expanding in rocks.

What is ice wedging?

400

A decrease in aquatic species, such as fish, may be an indicator of....

What is a decline in water quality?

400

Glaciers will melt from the Sun's energy and that water will be carried downhill, eventually ending up in this. 

What is groundwater?

400

The numbers found on topographic maps are know as this.

What are intervals?

400

Long periods of this would contribute to erosion along cliffs.

What is precipitation?

400

This substance can create chemical weathering when rocks are sitting in it. 

What is water? (Hydrolysis)

500

The largest dead zone in the world is located here.

What is the Gulf of Mexico?
500

This is what we call evaporation from plants.

What is transpiration?

500

The side of a mountain that is in the rainshadow is known as this.

What is leeward?

500

Erosion can be caused by these moving slowly downhill. 

What are glaciers?

500

Plants can create mechanical weathering due to this.

What is roots growing in cracks?
