Constructive
What is a constructive force?
Processes that cause the earths surface to build up.
What 2 processes are destructive forces
Weathering & erosion
What is weathering?
A process of breaking down rock into smaller pieces.
What is deposition?
The process by which sediment is laid down, dropped or deposited,
Earthquakes.
Trick question : Both
What are three of the main constructive forces?
Earthquakes, volcanic eruptions, and deposition of sediment.
What is erosion?
It is a destructive force that breaks down existing landforms to create new ones
What is erosion?
The carrying away of broken down sediment from one place to another.
How are volcanoes a constructive force?
By how they are made and after an eruption the lava cools and makes new landforms.
Floods.
Destructive
Name the landform that forms from deposition at the mouth of rivers.
Delta
What is a destructive force?
Its the process by which rock is broken down, such as erosion and weathering either through violent actions of volcanoes and earthquakes or by the steady flow of a river.
What are the three agents of weathering and erosion?
Water, Wind, and Ice (Gravity too)
Draw a model of a sand dune!
Based on picture
Breaking down of landforms?
Destructive
Constructive forces can be powered by:
Water, gravity, wind & glaciers.
What are destructive forces?
Its a type of force that destroys landforms
True or false : Weathering and erosion can create surface features.
False
What is a delta?
A land form that is formed at the mouth of a river?
Both
Which process is constructive? Weathering, erosion or deposition?
Deposition
What can mudslides be caused by
They can be caused by earthquakes, volcanoes. and gravity and water!
Describe an example of weathering
Describing rock arches, sidewalks cracking, ice wedging etc.
Describe how deposition works from start to finish!
Weathering happens first, the erosion moves the sediment and finally the sediment is dropped in a new place!
Building of land forms?
Constructive
