The establishment of the border illustrated on the maps is an example of how borders are created to-

• Establish Countries

• Divide Peninsulas

• Form Free Trade Zones

• Follow the course of rivers

How does a Geographic Information System (GIS) function as a resource for businesses or government officials?

• A GIS generates several surveys used to gather data about geographic patterns.

• A GIS presents data in visual forms making it easier to see geographic patterns

• A GIS creates a variety of predictions about geographic patterns for consumers

• A GIS produces reports about geographic decisions that have been made before.

Which human modification is most responsible for the physical geographic changes to the Aral Sea?

• Overfishing by commercial enterprises

• Polluting from nearby mining operations

• Redirecting water to grow crops in the desert

• Constructing dams on the rivers feeding the lake

The land reclamation project shown above was created in Dubai because

• the city is located below sea level

• the city is one of the fastest growing in the world

• the city needed protection from the threat of hurricanes

• the city’s new energy plants needed to be built near water

Based on the diagram, how does the Earth-Sun relationship affect the climate of different regions of the world?

• It creates a pattern where different areas of the globe receive differing amounts of sunlight.

• It creates a pattern in which the warm ocean currents bring monsoon rains to some regions.

• It creates a pattern in which the summers and winters are longer than fall and spring seasons.

• It creates a pattern where the eastern and western hemispheres have seasonal differences.

The landforms listed in the box are created by the physical process of —

• plate tectonics

• wind erosion

• weathering

• soil-building

Which of the following best describes the physical process that is responsible for creating flood zones shown on the map?

• Silt deposits along the major river systems create low lying areas that flood easily during spring snowmelt and seasonal rains.

• Tectonic forces in the Indian subcontinent cause upheavals of land which changes the course of rivers over time, causing flooding.

• India's growing population has led to the need to build huge dams along these rivers, which has led to the flooding of thousands of acres of land.

• High tides along the coast of the Indian Ocean often meet waters flowing from inland valleys causing the build-up of excess waters in the river systems.

The graphic above describes an earth shaping process that occurs in which of the following?

• Lithosphere

• Hydrosphere

• Biosphere

• Atmosphere

When the Northern Hemisphere is entering summer, the Southern Hemisphere is starting to feel the cold of winter. The sun’s glancing rays are spread over a greater surface area and must travel through more of the atmosphere before reaching the earth. There are also fewer hours of daylight in a 24-hour period. These seasonal differences are caused by —

• the South Pole being tilted away from the sun

• the South Pole being tilted toward the sun

• the earth's distance from the sun

• the relationship of the moon to the sun

How would this barrier affect the climate on the leeward side?

• The temperatures would be warm and the amount of precipitation low

• The temperatures would be warm and the amount of precipitation high.

• The temperatures would be very cold and the amount of precipitation high

• The temperatures would be extremely cold and the amount of precipitation low.
