Physical Processes & Formation Of The Earth Flashcards
What physical process causes mountains
Build up
How do volcanoes cause build up
They erupt to form mountains or new land as the lava cools
How do rivers cause wearing down
They carve valleys and channels into whatever material they flow over
True or false: older mountains have jagged peaks
False they have rounded peaks younger mountains have jagged peaks
What is weathering
The breaking down of rocks into smaller pieces by wind, water, ice and temperature
What is erosion
The picking up and movement of weathers rock and particles by wind water and ice
What is deposition
The laying down of sediment in a new location. Usually happens when wind or water carrying sediment slows down
What is the glaciation
The formation, movement and melting of ice sheets. Glaciers weather,erode and deposit sediment
What is a convergent boundary
It is when two tectonic plates come together causing mountains and volcanos
What is a divergent boundary
It is when two tectonic plates move away from each other causing new oceans and bodies of water
What is a transformation plate boundary
It is when two tectonic plates slide past each other
Name two reasons why Wagner believed his theory
1) the fit of the continents
2)fossil evidence
3)rock type similarities
4)evidence of glaciers in warm climates
What did Wagner notice about the continents
He noticed that they fit together like a jigsaw puzzle piece
What did Wagner notice about the fossils
He noticed that there where fossils from animals all the way across the world knowing that they can’t swim
What did Wagner notice about the rock similarities
He noticed that there was the same types of rock that where the same age along mountain ranges in different continents
