An area of new land at the mouth of a river, formed from sediments carried by the river.
What is a river delta
100
The process of moving sediment by wind, moving water, or ice
Erosion
100
Where would you most likely find a delta?
Near a river's mouth
100

What comes out of a volcano? What happens when it cools?

Lava; Igneous Rock forms

100

How are erosion and weathering different?

Weathering breaks down the rock while erosion moves the rock

200

This landform is created when two tectonic plates collide and one pushes up through the earth's crust : Convergent Plates

Mountains

200
What is weathering?
The process of breaking down rock by natural means
200

What is it called when the sand on the beach is replaced?

Beach Restoration

200
How do earthquakes happen?
The earth's plates collide on the fault lines
200

Which would quickly affect Earth's surface?

A. Earthquake

B. Rain

C. Erosion

A. Earthquake

300

Name 2 types of constructive forces

Fault, Earthquake, Volcano, Deposition, Wind (Sand Dunes)

300

What are the 2 types of weathering?

Chemical and Mechanical

300
How is moving water a destructive process?
Carries away broken rock/sediment. Can break down rocks into sediment.
300
What does a seismograph do?
Measures the earth's vibrations to track and predict earthquakes
300

Forms when a cave collapses

Sinkhole

400
This constructive force moves sediment through water until it is deposited to create a new landform
What is deposition?
400

How was the Grand Canyon formed?

Erosion

400

What is one land form made from erosion from water.

canyons, valleys, mesa, banks of a river, delta

400

How did the Hawaii Islands form?

Hot spots from volcanoes

400

Controls the flow of water and creates lakes

Dams

500
How are sand dunes formed
The wind blows the sand and can shape hills or mounds of sand called dunes
500
What are two phenomenon that can be both destructive and constructive depending on the situation?
Earthquakes and volcanoes
500

Prevents currents from carrying away sand

Jetty

500

Explain how  volcanoes can be both constructive and destructive forces

New land, and destroy land

500

How are technology and humans improving destructive and constructive forces on Earth?

Helping prepare and predict, lessening the impact
