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
100
What comes out of a volcano? What happens when it cools?
Lava Igneous Rock forms
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 types of constructive forces
Fault, Earthquake, Volcano, Deposition, Wind (Sand Dunes)
300

What are 2 types of weathering?

chemical and physical weathering

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
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
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
Explain how earthquakes and volcanoes can be both constructive and destructive forces
