IntroductionInternal Geology

External Geology

Atmosphere/Weather Climate

The sum of all living and non-living things that affect any living

organism

What is environment

Natural resources and natural services that help species live

and support an economy

What is natural capital

Environmental impact of a population=

What is population x consumption per

person (affluence) x technological impact

I = P A T

A pollutant that is widely dispersed and unable to be traced

back to a single source

What is a nonpoint pollutant

The equation for the rule of 70. What

does this equation determine?

What is Doubling time= 70/percentage

growth rate

The plastic region of the mantle

What is the asthenosphere

Tectonic plates move in opposite directions

at a

What is divergent plate boundary

The first vertebrates probably evolved

during this geologic era

What is the paleozoic era

Island arcs and volcanic arcs are

formed by this type of volcanism

What is subduction zone

Hotspots become progressively older

and inactive as

What is the lithospheric plate moves past the mantle plume

Most soil erosion is caused by these two

things

What is moving water and wind

The soil horizon that contains no organic

material and is composed of parent

material

What is the C horizon

The soil type that is most likely to become

waterlogged

What is clay

An agricultural style that prevents erosion

on steep slopes

What is terracing

A type of rock that is an important source

of many non-fuel mineral resources

What is igneous rock

The ozone layer is located within this

region of the atmosphere

What is the stratosphere

The release of gases by volcanoes which contributed to the

evolution of earth’s atmosphere

What is outgassing

The components of Earth’s first atmosphere

What is helium, hydrogen, ammonia,

methane

Three properties of air

What is Warm air rises, cool air sinks, warm air can hold

more water than cool air

When a warm front comes in contact with a cool front, this will

occur

What is the less dense warm front will rise up over the cool front, the moisture in

the warm air will condense forming

clouds and perhaps precipitation

The average temperature and precipitation of a region over a long

period of time

What is climate

The deflection of winds caused by the rotation of the Earth

What is the Coriolis Effect

The wind that brings warm air from the equator north and

south to 30o latitude

What are Easterlies (trade winds)

What happens to water vapor as air

cools.

What is it condenses and forms clouds

Effect of ENSO

What are decreased upwellings in

equatorial (tropical) Pacific oceans
