Plate Movement
a rigid section of Earth’s crust that moves very slowly
What is a plate?
when to continental crusts collide the resulting land surface feature is known as a
What is a mountain?
the rocky outer layer of Earth
What is the crust?
Hot rock rises and becomes less dense, cools off sinks and becomes more dense this phenomena is known as
What is convection?
This type of motion the crust is pulled or pushed apart away to form
What is a divergent boundary?
When an oceanic crust subducts underneath a continental crust the land surface feature that is created is known as a
What is a volcano?
the rigid upper layer of earth where people and plants reside
What is the lithosphere?
an ancient supercontinent that scientists believe existed from about 200 to 300 million years ago.
What is pangea?
Ocean Crust sinks below continent crust because it is more dense, this movement is known as
What is a subduction zone?
When pressure builds from plates colliding and releases energy this phenomena is known as
What is known as a earthquake?
the layer of Earth between the crust and the core, said to have viscosity and flow
What is the mantle?
a measurement of the size of the earthquake based on the amount of energy released
What is magnitude?
The two continents are equally dense, so neither sinks this convergent boundary creates
What is continent collision?
What is a hotspot?
This layer is a solid dense ball of iron and nickle
What is the inner core?
A measurement on a map of a location north or south of the equator
What is latitude?
What is transform boundary?
a crack in earth's surface due to tension from plate movement
What is a fault?
The liquid layer of iron nickel
What is the outer core?
Theory states the continents are moving very slowly proposed by Alfred Wegener in 1915, he discovered evidence that the continents were once joined together in a giant supercontinent called Pangea
What is the Theory of Continental Drift?
