land mass above water on Earth.
consists of the sun and eight known planets as well as other cellestial bodies around the sun.
the layer of gases immediately surrounding the earth
the outer part of the solid earth composed of rock.
the waters comprising the Earth's surface, including oceans, seas, rivers, lakes, and vapor in the atmosphere.
all the parts of the Earth where plants and animals live including the atmosphere, the lithosphere, and the hydrosphere.
the earth's center made up of iron and nickel; the inner core is solid, and the outer core is liquid.
a rock layer about 1,800 miles thick that is between the earth's crust and the earth's core.
the thin rock layer making up earth's surface.
the lateral movement of continents resulting from the motion of crustal plates.
the natural sequence through which water passes into the atmosphere as water vapor, precipitates to earth in liquid or solid form, and ultimately returns to the atmosphere through evaporation
the water beneath the surface of the ground, consisting largely of surface water that has seeped down; the source of water in springs and wells.
the surface of the water-saturated part of the ground, usually following approximately the contours of the overlying land surface.
a specific geomorphic feature on the surface of the earth, ranging from large-scale features such as plains, plateaus, and mountains to minor features such as hills, valleys, and alluvial fans.
the part of a continent that is submerged in relatively shallow sea.
the differences in the elevation and slope between the higher and lower parts of the land surface of a given area.
the detailed mapping or charting of the features of a relatively small area, district or locality.
the dozen or so plates that make up the surface of the Earth. Their motion is studied in the field of plate tectonics.
a place where sections of the crust of the Earth move relative to each other.
The point of the Earth's surface that is directly above the focus of an earthquake.
an unusually large sea wave produced by a seaquake or undersea volcanic eruption.
a vent in the Earth's crust through which lave, steam, ashes, etc., are expelled, either continuously or at irregular intervals.
Ring of Fire
the linear zone of seismic and volcanic activity that coincides in general with the margins of the Pacific Plate.
any of the various weathering processes that cause physical disintegration of exposed rock without any change in the chemical composition of the rock.
any of the various weathering processes that cause exposed rock to undergo chemical decomposition, changing the chemical and mineralogical composition of the rock.
the process by which the surface of the earth is worn away by the action of water, glaciers, winds, waves, etc.
what is formed when physical or chemical processes weather rock on or near the earth's surface?
which term names the type of weathering that changes the size of a rock, but not its composition?
a fanlike landform called a delta
what is created when a river carries sediment along its way to the ocean?
which term names the organic material that contributes to the fertility of soil?
Which term names a process by which moving masses of ice change the topography of a region?
Water and wind erosion can wash or blow away sediments and organic matter that help keep the soil fertile and that can be harmful to farmers, but water and wind erosion can also transport sediment and organic matter to the farmer's soil and this helps the farmer because it makes the soil fertile.
In what ways can water and wind erosion be both beneficial and harmful to farmers?
the difference in elevation of a landform from its lowest point to its highest point
Some of the water in the hydrologic cycle flows into the pores of the rock below the soil and becomes ground water.
what is the relationship between ground water and the hydrologic cycle?
the first planet from the sun
the second planet from the sun
the third planet from the sun
the fourth planet from the sun
the fifth planet from the sun
the sixth planet from the sun
the seventh planet from the sun
the eighth planet from the sun
the ninth planet from the sun
the rigid, rocky outer surface of the Earth, composed mostly of basalt and granite. It is thinner under the oceans.
the solid iron-nickel center of the Earth that is very hot and under great pressure
a rocky layer located under the crust-it is composed of silicon, oxygen, magnesium, iron, aluminum, and calcium. Convection (heat) currents carry heat from the hot inner mantle to the cooler outer mantle.
the molter iron-nickel layer that surrounds the inner core.
the process in which water pools in large bodies(like oceans, seas and lakes)
the process in which water vapor(a gas) in the air turns into liquid water. Condensing water forms clouds in the sky. Water drops that form on the outside of a glass of icy water are condensed water.
the process in which liquid water becomes water vapor(a gas). Water vaporizes from the surfaces of oceans and lakes, from the surface of the land,and from the melts in snow fields.
the process in which water(in the form of rain, snow, sleet, or hail) falls from clouds in the sky.
rain, snow melt, or other water that flows in underground streams, drains, or sewers.
rain, snow melt, or other water that flows in surface streams, rivers, or canals.
the process in which some water within plants evaporates into the atmosphere. Water is first absorbed by the plant's roots, then later exits by evaporating through pores in the plant.
moving pieces under the Earth's surface that form the Earth's crust are called .
a seismograph measures the size of the waves caused by .
a giant ocean wave that is sometimes caused by an earthquake is called .
magma can flow out of cracks in the earth's surface as .
the flow of magma through cracks in the earth's surface is called .
The Ring of Fire is the location of the vast majority of volcanoes, and volcanic action and earthquakes occur frequently there.
why is the Ring of Fire an appropriate name for the zone around the rim of the Pacific Ocean?
the solid rock portion of the earth's surface
a soft layer of molten rock under the earth's surface
the thin layer of rock that coats the earth's surface
the water elements on the earth
the layer of gases that surrounds the earth
the continental drift theory states that the earth was once a supercontinent that divided and slowly drifted apart over millions of years. The theory of continental drift explains the current sizes, shapes, and positions of the earth's continents because as the continents drifted apart after they divided into the different shapes from the super continent of Pangea they collided and moved until they were the current sizes, shapes, and positions of the current continents.
how does the theory of continental drift explain the current sizes, shapes, and positions of the earth's continents?
plates move apart spreading horizontally; an example is the one between the Saudi Arabia and Egypt the two plates on which those countries are sitting are spreading apart causing the Red Sea to become even wider.
plates collide causing either one plate to dive under the other or the edges of both plates to crumple; one example is found in South Asia. The plate where India is located is crashing into the Asian continent and building up the Himalayas.
plates slide past each other; one example is the San Andreas fault in California.
