process that changes rock into a new substance through interactions among elements

what is chemical weathering?

the air, water, and minerals in rocks

where does chemical weathering take place?

result of weathering on matter created by action of wind, water, ice, and gravity

what is erosion?

thin rock layer making up the earth's surface

what is the crust?

rock layer that is between the earth's crust and core

what is the mantle?

1800 miles

how many miles thick is the mantle?

center of the earth

what is the core?

iron and nickel

what is the core made up of?

molten rock material formed when solid rock in the earth's mantle or crust's melts

what is magma?

physical and chemical processes that change the characteristics of rock

what is weathering?

slow

is weathering a slow or fast process?

layers of gases immediately surrounding the earth

what is the atmosphere?

solid rock portion of the earth's surface

what is the lithosphere?

the waters comprising earth's surface

what is the hydrosphere?

oceans, lakes, rivers, seas, and vapor in the atmosphere

what is included in the hydrosphere?

all the parts of the earth where plants and animals live

what is the biosphere?

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

what is the hydrologic cycle?

area drained by a major river and its tributaries

what is a drainage basin?

the water held underneath the earth's surface, often in and around the pores of a rock

what is ground water?

the level at which a rock is saturated

what is a water table?

a naturally formed feature on the surface of the earth

what are landforms?

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

what is the continental shelf?

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

what is relief?

the combined characteristics of landforms and their distribution in a region

what is topography?

small pieces of rock produced by weathering

what is sediment?

hypothesis that all the continents were once joined into a supercontinent that split apart over millions of years

what is pangea?

wind blown silt and clay sediment that produces very fertile soil

what is a loess?

a large, long-lasting mass of ice that moves because of gravity

what is a glacier?

changing of landforms by slowly moving glaciers

what is glaciation?

ridge or hill of rock carried and finally deposited by a glacier

area where a large number of earthquakes and volcanic eruptions occur in the basin of the pacific ocean

what is the ring of fire?

93 million miles

how far is earth from the sun?

third

what number planet is earth to the sun?

winds blow over the ocean and pick up heat and distribute it to the land

how does the motion of the ocean distribute heat?

fold and crack

what happens when two plates meet?

planets, comets, asteroids, etc

core, mantle, crust

what are the layers inside the earth?
