This is the outermost layer of earth
What is the crust
100
The lithosphere is divided up into this.
What are tectonic plates?
100
Area which earthquakes and volcanoes line up near the Pacific Ocean.
What is the Ring of Fire?
100
States that the lithosphere is divided into 12 large plates and 20 smaller ones
What is the theory of plate tectonics?
100
How deep is the crust?
What is 0-100 km
200
This consists of liquid iron and nickel
What is outer core?
200
Proposed the idea to explain the evidence of continental drift.
Who is Alfred Wegener?
200
What are mid-ocean ridges?
Massive undersea mountain ranges, linked and running along the middle throughout world's oceans.
200
This type of boundary results in earthquakes
What is a transform boundary?
200
Name all three types of boundaries
What are transform, divergent and convergent boundaries.
300
This provide scientists with one of the best ways to directly observe Earth's interior
What are volcanoes
300
The land mass which the continents have split from.
What is Pangaea?
300
What is sea-floor spreading?
When magma rises from the mantle, and fills the crack left by the floor moving apart.
300
When a divergent boundary cuts across land
What is a rift valley?
300
How deep is the mantle?
What is 2900 km
400
This tell scientists about Earthquake dynamics and the structure of Earth
What are seismic waves
400
What is paleoglaciation?
Paleoglaciation is the extensive peroids in which glaciers covered most of the continents.
400
The magnetic orientation of the sea floor mirrors the side of the ridge, which is slowly moving away on both sides.
What is magnetic striping?
400
This created inland mountain ranges like the Himalayas
What are continental-continental convergent boundaries?
400
Basalt rock is rich in ______?
What is iron
500
This allow scientists to plot locations of geologic formations
What is Modern Mapping.
500
Name the evidences of Continental Drift.
The land mass fit into a puzzle, matching geological features on distant coastlines, identical fossils on distant coastlines, the presence of coal in non-tropical areas, and evidence of glaciers near the equator.
500
What evidence was shown to prove that the sea floor was spreading?
Radioactive dating of the ocean floor rock, patterns of magnetic striping, radioactive decay, and the features of the ocean floor.
500
The Nazca Plate is moving this way
