Rocks
Rocks that cool slowly tend to have _____________ crystals, and rocks that cool fast tend to have ______________ crystals.
What are larger crystals?
What are smaller crystals?
Where plates move away from each other
What is a Divergent Boundary?
Earthquakes mostly happen here
What are plate boundaries?
Formed by lava or magma
What are Igneous Rocks?
Breaks down rocks and minerals on Earth's surface
What is Weathering?
This kind of rock cools slowly
What are intrusive igneous rocks?
Where plates move toward each other
What is a Convergent Boundary?
This causes plate tectonics to move
What is the sinking of the lithosphere into the asthenosphere?
Layers found on the bottom are older or younger?
What are older?
Moves the weathered material around
What is Erosion?
This kind of rock cools quickly
What are extrusive igneous rocks?
Where plates move past each other
What is a Transform Boundary?
When the lava cools and hardens, it creates new land
What are divergent boundaries?
Example of a Sedimentary Rock
What is Sandstone, Shale, Conglomerate, Limestone, Dolomite, or Gypsum, etc?
When the eroded material settles and accumulates in a new location
What is Deposition?
Made of sediments and dead coral or shells
What are sedimentary rocks?
Subduction Zone
What are places along a convergent boundary where one plate moves under another plate?
The rising and falling of fluids, like the mantle, due to heating and cooling
What is Convection?
Example of Metamorphic Rock
What is Gneiss, Marble, Schist, or Quartzite, ect?
The process of decay or the breaking down of organic materials
What is Decomposition?
Formed by intense heat and pressure
What are Metamorphic Rocks?
If you found all three rock types (Igneous, Sedimentary, and Metamorphic) on the same mountain, what does this tell you about this mountain?
1. In the past, an ocean covered it (Sedimentary Rocks)
2. Faults allowed melted rock to come to the surface (Igneous Rocks)
2. This part of the plate has experienced intense heat and pressure.
We experience several earthquakes and then a line of volcanoes, from Kingsley to Florida, suddenly appears. What would you conclude happened?
The plate we are on has broken into two plates, and the resulting plates are now either divergent plates or convergent plates.
Example of Igneous Rock
What is Granite, Pumice, Obsidian, Basalt, or Gabbro, etc.?
The process for making soil
What are weathering, deposition, and decomposition?
