Unit 4 APES Review

Front

What layer of the atmosphere is responsible for weather phenomena such as pressure changes, wind, and precipitation?

Back

The troposphere.

Front

What occurs at a subduction zone between oceanic crusts?

Back

The denser oceanic crust is subducting under the less dense oceanic crust.

Front

What climatic phenomenon leads to a decrease in hurricane activity in the Atlantic Ocean?

Back

El Nino.

Front

What is the primary factor that explains global wind patterns?

Back

Unequal heating of the Earth.

Front

What event is characterized by stronger than usual trade winds?

Back

La Nina.

Front

What is the definition of the troposphere?

Back

The lowest layer of Earth's atmosphere where weather occurs.

Front

What is subduction in the context of plate tectonics?

Back

The process by which one tectonic plate moves under another plate and sinks into the mantle.

Front

How does El Nino affect ocean temperatures and weather patterns?

Back

El Nino causes warmer ocean temperatures in the central and eastern Pacific, leading to altered weather patterns.

Front

What role does the sun play in global wind patterns?

Back

The sun's unequal heating of the Earth's surface creates temperature gradients that drive wind patterns.

Front

What are trade winds and how do they relate to La Nina?

Back

Trade winds are prevailing winds that blow from east to west in the tropics; during La Nina, these winds are stronger than usual.
