World Geography Review

By: Casey Maas

What are longitude, latitude, the equator, and the prime meridian?

Longitude- splits the earth in to several different lines separating the north and south.

Latitude- splits the earth in to several different lines separating the east and west.

The equator- divides the earth in to the northern and southern poles.

Prime meridian- divides the east and west.

Why is the equator the warmest place on earth? What causes seasons? How is the earth divided in the hemispheres?

Sunlight from the sun directly hits the equator year round. Seasons are caused by the earths tilt. The equator sperates the earth in to the northern and Southern Hemispheres.

Weather- condition of the atmosphere at a particular location at a time

Climate- term for weather conditions at a particular location over a long period of time

Differences between relative and absolute location?

Relative- discribes a place in comparison to other places around it

Absolute- the exact place on earth where an area is located

A region is?

An area geographers call with one or more features that set it apart from other areas.

How do geographers reduce distortion when creating maps?

They use map protection

Geographic landforms most people live near- rivers, lakes, fertile plains, etc.

What are the factors that influence climate?

Latitude-most important factor in determining climate

Air masses- a large volume of air where temperature is same across horizontal bands

Continentality- when water takes longer to heat up and cool down than land

Elevation- the higher you get the colder it it

Mountain barriers- mountains stop storms and airmasses

Ocean currents- cold currents create dry conditions and warm currents create wet conditions

Pressure cells- where air rises it is rainy and humid and where air lowers it is light and warm

Storm tracks- when cold and hot combine makes storms

What are the climate regions and their characteristics?

Tropical rain forest- always hot and rains daily

Tropical wet or dry savanna- rainy season in summer with a dry winter

Steppe- about 16" rain per year

Desert- less than 10" rian per year

Mediterranean- hot, dry summers and cool, rainy winters

Marine west coast- northwest United States and Western Europe

Humid subtropical- in S.E. USA and subject to hurricanes

Subarctic- evergreen forests

Tundra- summers are so short and cool that permafrost occurs

Ice cap- known as polar desert

Highlands- climate varies

What is a climogroph?

A graph that indicates average temperature and precipitation for an area.

HEI

What is the greenhouse effect?

A layer of gases in the earths atmosphere that increases the earths temperature

What will happen if we continue to use fossil fuels at the same rate as we are now?

We will run out of fossil fuels

What is desertifiction?

Fertile land becomes desert because of drought, deforestation, or inappropriate agriculture.

What is an earthquake

As plates grind or slip past each other at a fault, the earth shakes

Seismograph- a device that can detect earthquakes

Focus- where the earthquake begins

Epicenter- right above the focus and the area where the ear quake begins on the surface
