Plate Boundaries
The type of boundary where two plates are moving towards each other?
Convergent Boundary
Gigantic pieces of the Earth's crust and uppermost mantle that slowly move and interact with one another are called?
Tectonic Plates
What geological phenomena occurs most often at transform boundaries?
Earthquakes
What is Pangaea?
A supercontinent formed when all of the landmasses on Earth were connected together.
Molten rock underneaths the Earth's surface is called?
Magma
The type of boundary where two plates are away from each other?
Divergent Boundary
The geological theory that states that pieces of Earth's lithosphere are in constant, slow motion is the theory of
Plate Tectonics
Divergent boundaries form these features?
(there maybe more than one correct answer)
Ridges, rifts, mountains
Alfred Wegener's theory of Plate Tectonics included the idea that after Pangaea, the continents slowly moved away from each other to the locations they are in today. This idea is called?
Continental Drift
The newest or youngest rocks are found farther or closer to the Mid-Atlantic ridge.
Closer
The type of boundary where two plates sliding past each other?
Transform Boundary
The scientist who first proposed the Theory of Plate Tectonics?
Alfred Wegener
Mountains
Scientists found evidence of Pangaea using the solidified remains of plants and animals in rock called?
Fossils
The San Andreas fault in California is an example of what boundary?
transform boundary
When continental crust moves towards continental crust a special convergent boundary is formed called a?
Collision Zone/boundary
What are the two types of crust?
Continental and Oceanic
What type of boundary is responsible for the formation of many volcanoes?
Convergent-Subduction
Scientists found evidence of Pangaea using the scraping of rocks made by huge slow moving mountains of ice called?
Glaciers
The layer of the Earth's crust that the tectonic plates are also comprised of is called the?
Lithosphere
A convergent boundary when one plate slides underneath another plate.
Subduction
Most geologists believe the movement of the plates is caused by?
convection currents in the Earth's mantle
The Mid-Atlantic ridge is a landform created by this type of boundary?
Divergent Boundry
Scientists found evidence of Pangaea using similarities of these objects that were created in the same time period, and were the same types and formations spread across different continents.
Rocks and mountain ranges.
The upper layer of the Earth's mantle where the tectonic plates slide or move across is called the?
Asthenosphere
