Combination Coast
Key Learning(s):
The Earth is made up of different layers that are dynamic. There is a connection between the features of the Earth and the rock
cycle. Phenomena such as earthquakes and volcanoes result from tectonic activity. The current location of the continents is the result
of past plate movement and is continually changing. Sand forms in many different ways. There are differences between
active/passive and primary/secondary coasts. Humans make modifications to the coastline for many reasons.
Unit Essential Question(s):
How is Earth’s inside different from its outside?
What is Continental Drift and Seafloor Spreading?
What can sediments tell you about biological productivity and ecological concerns?
How do we classify sediment?
How do sedimentation processes differ based on their location?
How are coasts classified and how do they change over time?
