Earth's spheres
The earth moves
Shaping Earth
Earthquakes
Volcanoes
100

the regions of the earth occupied by living organisms

BIOSPHERE

100

Wegener’s hypothesis that Earth’s continents were joined as a single landmass

CONTINENTAL DRIFT

100

Movement of weathered materials from one location to another

EROSION
100

Type of boundary associated with earthquakes; two plates move horizontally past each other

TRANSFORM BOUNDARY
100

Bowl-shaped depression that forms around the central vent at the summit of a volcano.

CRATER
200

The rock cycle exists in this sphere

LITHOSPHERE/GEOSPHERE

200

Type of boundary where two of Earth’s tectonic plates are moving toward each other

CONVERGENT

200

process that breaks down and changes rocks on or near Earth’s surface

WEATHERING

200

Point on Earth’s surface directly above the focus of an earthquake

EPICENTER

200

molten/melted rock that reaches the Earth’s surface

LAVA

300

This sphere provides the driving force for cloud formation

HYDROSPHERE

300

An unusually hot area fed by a plume in Earth’s mantle, which creates a chain of volcanoes as the plates move above them.

HOT SPOT

300

the final stage of the erosional process in which the movement of transported materials slows and they are dropped in another location.

DEPOSITION

300

Point of the initial fault rupture where an earthquake originates that usually lies at least several kilometers beneath Earth’s surface

FOCUS

300

Ocean where 75% of the world's volcanoes are located

PACIFIC OCEAN

400

This sphere is responsible for keeping the planet sustainably warm and inhabitable

ATMOSPHERE

400

Process by which one tectonic plate slips beneath another tectonic plate.

SUBDUCTION

400

These are two main agents of erosion

WATER AND WIND

400

Record produced by a seismometer that can provide individual tracking of each type of seismic wave.

SEISMOGRAM

400

A substance’s internal resistance to flow.

VISCOSITY

500

This process is an interaction between the biosphere, atmosphere, and hydrosphere that gas exchange between plants and air

TRANSPIRATION

500

Plates pull apart and create a crack in the ocean floor, where magma fills the space between. When magma spreads outward, it creates a mid-ocean ridge and new crust.  

SEAFLOOR SPREADING
500

Two main types of weathering

CHEMICAL, MECHANICAL

500

Common scale used to measure the magnitude of an earthquake

RICHTER SCALE
500

Intrusive or extrusive rock formed when hot magma cools and crystalizes (hardens).
