100
What is the process by which small pieces of rock are moved from one place to another called?
What is erosion?
100

This landform is a body of water enclosed (surrounded) by land:

What is a Lake?

100
Small pieces that break off of rocks.
What is sediment?
200
Rusting from Oxidation.
What are Chemical Weathering?
200

What stays the same in an experiment?

Constant/Control Variable

200
The Colorado River eroded it into the Gulf of California.
What is the Grand Canyon?
200

This landform is a body of land enclosed (surrounded) by water.

What is an Island?

200
Gigantic formations of ice that do not completely melt over the course of years.
What is a glacier?
300
Which one of these things is not an agent of weathering? - Water - Wind - Ice - Soil
What is soil?
300

The results of an experiment, the measured variable.

dependent

300
The dropping of rocks (sediment) in a new place.
What is deposition?
300

This landform is formed when sand is eroded and deposited into a large pile... often found in the desert or along a coastline.

What is a dune?

300

This type of physical weathering involves water seeping into cracks in a rock, freezing and splitting it.

What is frost wedging?

400

This type of weathering involves rock splitting due to melting and freezing of water.

What is physical weathering?

400
You decide to test two different rivers to see which one erodes faster. You drop a tennis ball in each river and measure how long it takes to erode (move) 50 feet. What is the dependent variable?
Time
400
This is NOT a cause of Erosion - Fire - Wind - Gracier - Water
What is fire?
400

This landform is formed at the head of a river as it deposits eroded material into a lake, sea or ocean.

What is a delta?

400

The dissolving of rock or changing of its mineral composition.

What is Chemical Weathering?

500
Acidic groundwater forming caves
Chemical weathering
500
You decide to test two different rivers to see which one erodes faster. You drop a tennis ball in each river and measure how long it takes to erode (move) 50 feet. What is the independent variable?
Two different rivers
500

Rock and sand dropped by melting glaciers?

What is Deposition?

500

This landform is formed when sediment deposits in the ocean along a coastline. It can prevent erosion of the coastline by blocking waves.

What is barrier island?

500

This landform forms when layers of limestone are dissolved away through chemical weathering and gravity pulls overlying layers into the Earth.

What is sinkhole?
