Lesson 1
Hydrosphere
What is the water areas of the Earth, including oceans, lakes, rivers, and other bodies of water
Core
What is the innermost layer of the Earth made up of a super-hot but solid inner core and a super-hot liquid outer core
Magma
What is molten rock that is located below Earth's surface
Fault
What is a crack of break in Earth's crust
Water Cycle
What is regular movement of Earth's water from ocean to air to grounf and back to the ocean
Lithosphere
What is the uppermost layer of the Earth that includes the crust, continents, and ocean basins.
Mantle
Subduction
What is the process by which oceanic plates dive beneath continental plates, often causing mountains to form on land
Faulting
What is the process of cracking that occurs when the folded land cannot be bent any further
Evaporation
What is the process of excess water vapor changing into liquid water when warm air cools
Atmosphere
What is a thin layer of gases that surrounds the Earth
Crust
What is outer layer of the Earth, a hard rocky shell forming Earth's surface
Accreation
What is the slow process in which an oceanic plate slides under a continental plate, creating debris that can cause continents to grow outward
Weathering
What is the cheical or physical processes that break down rocks into smaller pieces
Condensation
What is the process of excess water vapor changing into liquid water when warm air cools
Biosphere
What is the part of the Earth where life exists
Continental Drift
What is the theory that the continents were once joined and then slowly drifted apart
Spreading
What is the process by which magma wells up between oceanic plates and pushes the plates apart
Erosion
What is the movement of weathered rock and material by wind, glaciers, and moving water
What is moisture that falls to the Earth as rain, sleet, hail, or snow
Continental shelf
Plate tectonics
What is the term scientists use to describe the activities of continental drift and magma flow, which create many of Earth's physical features
Fold
What is a bend in layers of rock, sometimes caused by a plates movement
What is piles of rocky debris left by melting glaciers
Desalination
What is the removal of slat from seawater to make is usable for drinking and farming
