Terms in this set (26)
Inner core, outer core, mantle and crust
Name the 4 layers of the earth
A German scientist who proposed the theory of continental drift
A supercontinent containing all of Earth's land that existed about 225 million years ago.
Name of Wegener's theory
Continental Drift Theory
The idea that Earth's continents move apart from a single large continent called Pangea.
Fossils, continental fit, glaciers, land-forms and rock forms
The 4 evidences that Wegener gave to support his theory.
Proposed the theory of sea-floor spreading.
Sea floor spreading
The rising and sinking of magma causes tectonic plates to move.
Wegener's and Hess's theories combined gave way to what theory?
Plate Tectonics Theory
The Earth's outer layer is divided into several plates that glide over the asthenosphere.
A trace of an ancient organism that has been preserved in rock or other material.
convection currents in the mantle
What moves the plates of the Earth?
The layer of rock that form the continents
A thin layer of crust that underlies the ocean basins
A plate boundary where two plates move away from each other. They move apart or divide
A tectonic plate boundary where two plates collide, come together, or crash into each other.
The boundary between tectonic plates that are sliding past each other
MOUNTAINS Example: Himalayan Mountains
What type of landform is made with convergent plate boundary collision? Name an example
Volcanoes on land and in the ocean
What type of landform is made with convergent plate boundary subduction? Name an example
example Great Rift Valley in Africa
Oceanic-mid ocean ridge
example Mid Atlantic Ridge in Atlantic Ocean
What type of land form is made with divergent plates? Give an example
Earthquakes and fault lines
Example: San Andreas Fault line in California
What happens when transform plates slide past each other? Give an example
Ring of Fire
The chain of volcanoes that lines the Pacific Ocean Rim. It is geologically the most active area on Earth. Frequent earthquakes and volcanic eruptions happen here _________________
