Question 3

What is a collisional coast

Answer 3

Lies along the edge of an active convergent plate. Often associated with earthquakes and volcanic activity.

Answer 4

Straight coast
Narrow continental shelves
Steep continental slopes
High mountains adjacent to the coast.
Ocean trenches

Question 9

Describe vegetation that exists on the coasts of cold, high-latitude climates.

Answer 9

Cold, tundra - bushes, grass, mosses, liechen

Question 10

What are the 2 types of weathering?

Answer 10

Mechanical - rocks are broken apart from a physical process

Chemical - chemical reactions dissolve or alter minerals in rocks.

Question 11

How does weathering impact the shape of a coastline?

Answer 11

Shoreline erosion can occur over time and reduce the size of the beach and cause exposed bedrock and erosions scarps and cliffs.

Question 12

How do storms impact the shape of a coastline?

Answer 12

Depending on the storm significant deposition of sediment can occur or significant erosion and removal of sediment. Storm bars can be created.
