Unit 2 Review - World Geo - Canada/United States

Front

How does elevation affect temperature?

Back

Temperature decreases as elevation increases.

Answer explanation

As elevation increases, the atmosphere becomes thinner, leading to lower air pressure and temperature. Therefore, temperature decreases as elevation increases, making this the correct statement.

Front

Why are coastal areas of Canada warmer than inland areas at the same latitude?

Back

Ocean water moderates temperatures

Answer explanation

Coastal areas are generally warmer than inland areas at the same latitude because ocean water moderates temperatures, absorbing heat in the summer and releasing it in the winter, leading to milder conditions along the coast.

Front

What process mainly formed the Rocky Mountains?

Back

Tectonic plate collision and uplift

Answer explanation

The Rocky Mountains were primarily formed by tectonic plate collision and uplift, where the North American Plate collided with other plates, causing the land to rise and create the mountain range.

Front

Why is Los Angeles cooler than Dallas or Florida at similar latitudes?

Back

Ocean currents and coastal influence

Answer explanation

Los Angeles benefits from ocean currents and coastal influences that moderate its temperatures, making it cooler than Dallas or Florida, which lack this effect despite being at similar latitudes.

Front

How do ocean currents affect climate?

Back

They warm or cool coasts by moving heat.

Answer explanation

Ocean currents play a crucial role in climate by redistributing heat across the planet. They can warm or cool coastal regions, influencing local climates significantly, making this the correct choice.

Front

Which U.S. region is most densely populated because of harbors and rivers that help industry and trade?
