C and D forces
100
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/ end of the river

100

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

Lava which can then cool off over thousands/ millions of years and creates new land

200
This landform is created when two tectonic plates collide and one pusses up through the earth's crust : Convergent Plates
Mountains
200
What is weathering?
The process of breaking down rock by natural means
200
Why do sand dunes most likely form by an ocean
Water and wind can both move sand. Sand dunes form where the wind is strong and the sand deposits are plentiful. That is why the beach is the perfect location for them!
200
How do earthquakes happen?
The earth's plates collide on the fault lines
300

Name 3 landforms of constructive forces

Mountain, Earthquake, Volcano, deposition of wind to create Sand Dunes

300

What are 3 natural ways weathering can occur?

Acid Rain, Ice expanding (cracking surfaces), tree roots growing and cracking roads, wind, water

300
How is moving water a destructive process?
Carries away broken rock/sediment. Can break down rocks into sediment.
300

Earthquakes can cause slow change or rapid change to Earth's surface.

Rapid change

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

Name one way humans are a destructive force on nature?

Pollution, deforestation, over crowding, carbon footprint,

400
What is one land form made from erosion from water.
canyons, valleys, mesa, banks of a river, delta
400

How did hawaii form?

Hot spots / plates shift over a hot spot/ Volcanoes

500

How are sand dunes formed

Erosion of wind blows and deposits 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
What type of rain is especially destructive?
Acid Rain
500
