Plates 101
Earth’s surface is broken into moving pieces called this.
Tectonic / Lithospheric Plates
This boundary forms when plates move apart.
Divergent
Rock formed when lava cools.
Igneous
Rock and soil moving down a slope is called a ....
Landslide
What was Alfred Wegener's idea called and what was it?
Continental Drift - The idea that continents were once joined together (Pangaea) and separated over time
This boundary occurs when two plates collide, creating mountains, trenches, and volcanoes
Convergent
Rock formed from pressed and glued sediments. (or compacted and cemented)
Sedimentary
What causes a landslide?
Heavy rain, earthquakes, gravity
What is Plate tectonic theory?
The theory that Earth used to be Pangaea but the lithospheric / tectonic plates caused the continents to move to where they are found today
This boundary is where plates slide / where earthquakes are most common.
Transform
Rock changed by heat and pressure.
Metamorphic
What is the difference between an aquifer and an aquitard? Which does groundwater end up in?
Aquifer = Water passes through (Groundwater)
Aquitard = Water cannot pass through
What is ONE piece of evidence that could support Plate Tectonic theory?
S = Shape
M = Modern Day plants and animals
R = Rocks
F = Fossils
The process where one plate sinks under another is called...
Why is the rock cycle called a cycle?
It’s called a cycle because it keeps going again and again, and rocks can change from one type to another in many different ways.
Name a tool that a scientist could use to either 1. track earthquakes or 2. track plate movements
2. GPS (Track Tectonic Plates)
What are the two things that move plate tectonics? BE SPECIFIC
New lithosphere is created at this type of boundary.
Divergent Plate boundaries. Plates spread apart and new magma rises / cools to form new crust.
True or False:
A sedimentary rock can change into a sedimentary rock
How is copper, granite, AND petroleum a resource? What does each rock offer as a resource to humans.
Copper = __________________________________
Granite = _________________________________
Petroleum = _______________________________
Copper = Wires, plumbing
Granite = Countertops, buildings, statues
Petroleum = Gas, oil, fuel
