Tectonic Plate Movements
Plates SLIDE against one another
Transform boundary
True or False: In Russia, people were able to dig through Earth's crust and reach the mantle layer.
False!
What continent do we live on?
North America
What is a DORMANT volcano?
Type of rock formed when lava cools
Igneous Rock
Plates COLLIDING with one another
convergent boundary
the layer of Earth we live on
crust
List 2 continents, other than North America
South America, Africa, Asia, Antartica, Australia, Europe
True or false: volcanoes often show up along the coast of continents
True
Type of rock formed from sediments and pressure
Sedimentary rock
Plates moving APART from one another
divergent boundary
Earth's layer made of melted rocks (like pudding)
Mantle
What is the term for continents moving apart from each other?
Continental drift
How do volcanoes form?
Convergent plate boundaries (plates collide and build up new crust)
Divergent plate boundaries (plates move away from each other and allow room for magma to rise to Earth's crust)
Type of rock formed due to extreme pressure and heat
metamorphic
Plate movement that creates mountain ranges
Convergent
outer core
How long ago did Pangaea exist?
200-400 million years ago
What comes out of a volcano during an eruption? (list 3 things)
lava, rock, ash, gas, smoke
Moving sediments and rocks from one place to another is the process called:
Erosion
Plate movement that creates an opening in the Earth's crust and allows magma to rise to surface
Divergent
Earth's layer that is solid (besides the crust)
Inner Core
List one piece of evidence to support that the supercontinent, Pangaea, existed
1. Fossils found on neighboring continents (lystrosaurus fossils)
2. Continents fit together like puzzle pieces
What is the Ring of Fire?
A path of active volcanoes (shaped like a horse shoe) around the edges of the pacific ocean due to convergent plate movement
The process by which earth’s surface is broken down into smaller pieces.
