World Geography Chapter 2 A living Planet

earth's oute rmost layer

device that records ground movements caused by seismic waves as they move through Earth

Combined characteristics of landforms and their distribution in a region.

thick layer just between crust & core containing earth mass

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

Magma that reaches Earth's surface

Small pieces of rock produced by weathering processes.

A mixture of gases that surrounds a planet, such as Earth.

A weak spot in the crust where magma has come to the surface

A fine light silt deposited by wind and water

Spherical central mass of Earth of iron & nickel & outer layer liquid & interior solid 

Difference in elevation between the highest and lowest point in an area

continuous circulation of water among the atmosphere, the oceans, and the earth.

large land masses above water on Earth

Condition in which the earth's surface is worn away by the action of water and wind

hypothesis that states that the continents once formed a single landmass, broke up, and drifted

A natural structure on Earth's surface

Water that fills the cracks and spaces in underground soil and rock layers

The earth's surface from the edge of a continent to the deep part of the ocean.

breaking down of rocks and other materials on the Earth's surface

The type of weathering in which rock is physically broken into smaller pieces

Shaking & vibrationat the surface of earth resulting from underground movement along a fault

collection of planets & their moons in orbit around a sun 

Material formed from decaying leaves and other organic matter

A giant wave usually caused by an earthquake beneath the ocean floor.

The changing of landforms by slowly moving glaciers

Earth's solid, rocky outer layer

A large mass of moving ice and snow.

A triangular area of land formed from deposits at the mouth of a river

all life on Earth & parts of Earth in which life exists, including land, water, atmosphere.

crack in the earth crust resulting from the displacement of one side with respect to the other

An area drained by a major river and its tributaries.

All the water of planet that is in ocean and on land and in the atmosphere makes up this layer.

Large movable plates under the Earth's surface.

process in which rockis broken down by changes in its chemical makeup

A circle of volcanoes surrounding the Pacific

A scale that rates an earthquake's magnitude based on the size of its seismic waves.

A ridge formed by the till deposited at the edge of a glacier.

molten mixture of rock-forming substances, gases, and water from the mantle
