World Geo Unit 1 Review

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.

Which of the following is most directly responsible for the variation in seasonal weather patterns?

• The distance from the sun

• The tilt of the Earth's axis

• Ocean currents

• Wind patterns

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

• plate tectonics

• wind erosion

• weathering

• soil-building

The process of erosion can best be described as the movement of weathered materials by —

• river systems

• tectonic forces

• wind, water or ice

• human environmental interaction

"The world's oldest desert, The Namib Desert, has existed for at least 55 million years, and completely lacks surface water. The extremely arid region is made up of shifting sand dunes, gravel plains and rugged mountains...There is great variation in rainfall between years, with the driest areas of the desert having the highest variation."
According to the excerpt, The Namib Desert was formed due to —

• Climatic forces

• tectonic forces

• human habitation

• overgrazing

River deltas are found on the lower reaches of rivers, where the flow of water spreads out and slows down, depositing sediments into expanses of wetlands and shallow water. There are two types of deltas: coastal deltas where the river meets the sea and inland deltas where the river fills extensive floodplains and marshes. One of the most famous African examples of an inland delta is the Inner Niger Delta in Mali. Which physical environmental process is responsible for the creation of the types of landforms described in the excerpt?

• Erosion

• Droughts

• Ocean currents

• Tectonic plate movement

Which physical process is most responsible for the formation of islands in the Pacific Ocean?

• Erosion

• Droughts

• Ocean currents

• Tectonic activity

Which physical process contributes to the reduction in the size of islands in the Pacific Ocean over time?

• Erosion

• Glaciation

• Volcanism

• Deposition

Match each effect of hurricanes with the Earth system it most directly affects. Select ONE correct answer in each row.

• Beaches and shorelines erode

• Biosphere

• Birds lose their eggs and nest

• Lithosphere

• Inland lakes & streams are contaminated

• Hydrosphere

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.
