World Geography Chapter 2 review

A giant wave in the ocean caused by an underground earthquake 

spheres covered with ice and dust that leave trails of vapor as they race through space

Who initially created the Continental Drift Theory?

Organic material in the soil

Processes that break rock into smaller pieces are referred to as

plates slide past eachother at a fault

rocks left behind from a glacier that form a ridge or hill 

measures the size of the waves created by and earthquake 

A super-continent that existed during the late Paleozoic and early Mesozoic eras

A fracture in the Earth's crust

When plates grind or slip past each other and cause violent movement

Naturally formed features on the surface of the earth are 

refers to the difference in elevation of a landform from lowest to highest point 

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

States that all continents were once a super continent that divided and slowly drifted apart 

The salty water of the ocean circulates through 3 basic motions

Small pieces of rock createdby weathering (mud, sand or silt) 

uses information collected by seismographs to determine the strength of an earthquake 

What is interconnected and covers over 70% of the Earth

What is the 3rd Planet from the sun?

How many known planets are in our solar system?

Magma rises from the mantle as plates spread apart from each other

Water held in the pores of rocks

The part of the earth where plants and animals live 

Solid rock portion of the earth- includes crust and uppermost mantle, oceanfloor,

sediment is deposited in a fan-like landform when a river enters an ocean 

Process referring to the physical and chemical processes that change characteristics of rocks

Enormous moving pieces that form the Earth's crust

Processes that change rock into a new substance

Magma that has reached the Earth's surface

As plates push together, one is forced under the other

The reshaping of landforms that occurs when weathered material is moved by wind, water or ice

The longest continuous mountain range on the ocean floor is the

Geographers call an area drained by a major river and its tributaries a

a loose mixture of weathered rock, organic matter, air, and water that supports plant growth

Made up of water elements of the earth(oceans, seas, rivers,lakes and water in the atmosphere 

combination of the surface shape and composition of landforms and their distribution in an area

Center of the Earth

Occurs when magma, gases, and water collect in underground chambers and eventually pour out

The water on earth is continuously circulated between the atmosphere,the oceans,and the earth 

Large, long lasting masses of ice that move because of gravity

Wind erosion causes

95% of active volcanos are located around the rim of the pacific ocean called...

thin layer of rock at the earth’s surface 

a mixture of molten or semi-molten rock, found beneath the Earth's crust

When water transports tiny rocks/sediments downstream

More than 95% of all freshwater is held by 

Changing of landforms by slow moving glaciers

layer of gases surrounding the earth-protects the earth from radiation and space debris

Surrounding the core and containing most of Earth's mass
