General Knowledge
The three main layers of Earth.
What are core, mantle, and crust?
This type of fault is typically found in oceans and causes a mid-ocean ridge.
What is a DIVERGENT fault?
The four main ocean basins on Earth.
What are PACIFIC, ATLANTIC, ARCTIC, and INDIAN oceans?
This hypothesis developed by Alfred Wagner explains the movement of Earth's tectonic plates.
What is CONTINENTAL DRIFT?
True or False? The magnetism of the Earth's ocean floor changes every few million years and can be measured in rocks that contain iron.
What is TRUE?
The scientific name for the Earth's crust.
What is the lithosphere?
This type of fault typically causes earthquakes due to the tectonic plates scraping past each other.
What is a TRANSFORM fault?
The ________________ hemisphere contains 2/3 of all land on Earth and is 61% ocean.
What is the NORTHERN hemisphere?
This stationary plume of magma rising from the mantle causes volcanic islands to form such as Hawaii.
What is a HOT SPOT?
90% of all earthquakes and 75% of all active volcanoes and on Earth can be found in this region on the Pacific Plate.
What is the RING OF FIRE?
This type of current drives the movement of tectonic plates.
What is CONVECTION current?
This type of convergent fault is best known for causing volcanoes.
What is an oceanic-continental convergent fault? *ocean-continent
This ocean basin is growing in surface area due to a moving tectonic plate.
What is the ATLANTIC?
The deepest place on Earth's ocean floor.
What is the MARIANA TRENCH?
This theorized continent means ALL EARTH and was suggested to have been the supercontinent that existed 250 million years ago.
What is PANGEA?
True or False? The oceanic crust is thicker and less dense than the continental crust.
What is FALSE?
This type of convergent fault is best known for causing mountain formations.
What is a continent-continent convergent fault?
This portion of the ocean floor has the greatest biodiversity due to its shallow depth allowing sunlight to spread.
What is the continental shelf?
This part of the ocean floor is incredibly flat due to the immense amount of pressure.
What is the ABYSSAL PLAIN?
Satellite findings show that Australia and Hawaii travel about this many inches per year.
What is ~ 3.0 inches?
This process prevents the Earth's crust from growing despite seafloor spreading.
What is the Subduction of old oceanic crust?
This type of geologic formation is formed as a result of ocean-ocean convergent faults where one ocean plate is pushed back into the mantle.
What is a deep sea trench?
The four major ocean basins in order from deepest to shallowest.
What is the PACIFIC> INDIAN > ATLANTIC> ARTIC?
This is the scientific name for the Earth's mantle.
What is the asthenosphere?
The Earth's core is mostly composed of this element.
What is IRON?
