Layers of Earth Rocks and Minerals Continental Drift Seafloor Spreading Plate Tectonics

100

What is geologists
Scientist who study the forces that make and shape the Earth are called

100

What is Basalt
The oceanic crust consist mainly of this type of rock

100

Who is Alfred Wegener
This Scientist developed the Continental Drift hypothesis

100

What is subduction
the process by which oceanic crust sinks beneath trenches

100

What is a fault
A break in Earth's crust where rocks have slipped past each other.

200

What is upper mantle and outer core
these two layers are liquid like "laffy taffy."

200

What is granite
The continential crust consist mainly of this type of rock

200

What is South America and Africa fit like jigsaw puzzle pieces
This is an example of the land formation evidence that supported Wegener's Continential Drift Theory

200

What is molten material/magma
what erupts through the valley of the mid-ocean ridge

200

What is plates
Earth's lithosphere is broken into separate sections called what.

300

What is the inner core
This layer is the most dense, hottest, and deepest.

300

What is igneous, sedimentary and metamorphic
List the three types of rocks

300

What is Lystrosaurus, mesosaurus, or glossopteris
Name one of the three examples of fossil evidence that supported Wegener's Continential Drift Theory

300

What is seafloor spreading
the process that continually adds new material to the ocean floor.

300

What is scientific theory
a well-tested concept that explains a wide range of explanations

400

What is outer core
The spin of this liquid layer around the inner core is what creates Earth's magnetic field

400

What is density
this is a measure of how much mass there is in a volume of a substance D=M/V

400

What is Glacial Deposits fround in South Africa
This is an example of the climate evidence supporting Wegener's Continential Drift Theory

400

What is Magnetic stripes
This discovery provided evidence for Seafloor Spreading, when scientist used very sensitive instruments to locate these patterns or strips on the ocean floor.

400

What is convergent boundary
the result of a collision between two plates

500

What is Convection currents
This is driven by hot and cold tranfer creating a change in density and is the force that moves the lithospheric plates that cause major geological damage on Earth's surface

500

What is melt
Metamorphic and sedimentary rock has to do this before it becomes igneous rock

500

What is explain what force pushes or pulls continents
Scientist rejected Wegener;s theory because he could not do this.

500

What is drilling samples
This evidence provided the final proof of seafloor spreading, using the Glomar Challenger in 1968 to to send pipes 6 kiolmeters deep into the ocean floor.

500

What is divergent boundaries
these boundaries occur at mid-ocean ridges or rift valleys
