Rocks
Name the 3 types of rocks.
Igneous, Sedimentary, and Metamorphic
The crust is _____ and ______.
Cool and solid.
How are mountains and trenches made?
Plates moving together or moving apart.
What is Weathering
Breaking into smaller pieces.
What is a volcano?
A mountain or place in the Earth where magma/lava may exit.
How are Igneous Rocks formed?
Melted Rock Cools on the Earth's Surface.
The mantle is _____ and ______.
Hot and Liquid.
What is Continental Drift?
Scientific Theory that states that the continents of the Earth move at a very slow rate.
What is Erosion?
Moving broken pieces from one place to another.
What is an Earthquake?
The shaking of the Earth because of the Plates.
How are Sedimentary Rocks formed?
Weathering, erosion, deposition, and then a lot of pressure.
The core is _____ and ______.
Very Hot and Solid
Double Jeopardy. Bet your points
Write down two pieces of evidence for Continental Drift.
Fossils. Mountain Ranges. Rocks Layers of the Earth's Crust.
Name the 3 kinds of Mechanical Weathering.
Plants/Animals, Abrasion, and Ice Wedging.
Describe how an Earthquake Happens.
The plates become pressed together and eventually they slip across each other or suddenly move.
Daily Double (800 Points)
Write down how a Metamorphic Rock becomes an Igneous Rock.
Weathering, erosion, deposition, and then brought back down to the mantle and melted into molten rock, and then finally released by a volcano and allowed to cool.
Describe how the molten rock in the mantle moves.
Hot rock rises, cools near the crust, and then falls back down to the core.
Describe how the plates move.
Very slowly over a long period of time. The mantle carries heat from the core and moves the plates, pushing them in different directions.
What is Chemical Weather?
Weathering carried out by a chemical reaction that removes/changes the material of the rock.
Where do volcanoes form?
Around the edges of the plates.
