Module 2, Lesson 3 Flashcards
What are shapes on the planet’s surface (mountains, valley, hills, plains, islands, peninsulas)?
Landforms
Where are the forces located that have shaped with Earth’s landforms by colliding, separating, and sliding plates over time?
Forces Below Earth’s Surface
What are large landmasses that are part of the Earth’s crust?
Continents
The Earth’s surface is divided into a dozen or so slow moving plates
Plate Tectonics
Why do plates move?
Energy deep inside the planet put pressure on the Earth’s crust
What causes energy created from a collision that produces distinct landforms?
Plates Collide
What is it called when plates move apart?
Plates Separate
What is magma that reaches the Earth’s surface?
Lava
What are sudden violent movements of the Earth’s crust?
Earthquakes
The process by which rock is broken down into smaller pieces
Weathering
What are some factors of weathering?
daytime heating & nighttime cooling; water gets in cracks and freezes; roots of trees; rocks eventually break down
The movement of sediment from one location to another
Erosion
What is the most common cause of erosion?
Water
A process where rivers create floodplains when they flood their banks and deposit sediment along the banks
Alluvial Deposition
What can influence where people settle?
Earth’s landforms
