APES Unit 4 Quiz

This video covers Unit 4 of the APES Ultimate Review Packet, focusing on Earth Science. It explores plate tectonics, soil formation, atmospheric layers, global wind patterns, watersheds, Earth's seasons, and the El Nino Southern Oscillation. The video provides a comprehensive understanding of how these elements interact to shape our planet's climate and geography.

What is the primary reason tectonic plates are able to float on the mantle?

• The mantle is composed of water.

• Tectonic plates are less dense than the mantle.

• The mantle is a liquid due to heat from Earth's core.

• The mantle is a solid layer.

Which type of plate boundary is most likely to cause earthquakes?

• Transform boundary

• Divergent boundary

• Convergent boundary

• Subduction zone

What is the main difference between weathering and erosion?

• Weathering involves the movement of rocks.

• Erosion breaks rocks into smaller pieces.

• Weathering is the breakdown of rocks, while erosion is their movement.

• Erosion occurs only in water.

How does soil pH affect plant growth?

• Higher pH levels increase nutrient availability.

• Lower pH levels can leach nutrients and damage roots.

• Neutral pH levels are harmful to plants.

• Soil pH has no effect on plant growth.

Which layer of the atmosphere is closest to Earth and where weather occurs?

• Thermosphere

• Stratosphere

• Mesosphere

• Troposphere

What is the primary cause of the Hadley cell circulation?

• Mountain ranges

• Earth's rotation

• Ocean currents

• Uneven heating of Earth's surface by the Sun

What is a watershed?

• An area of land that drains into a central body of water

• A mountain range that affects climate

• A body of water that flows into the ocean

• A type of soil formation

How does Earth's tilt affect the seasons?

• It affects the speed of Earth's rotation.

• It causes Earth to be closer to the Sun in summer.

• It results in one hemisphere receiving more direct sunlight.

• It changes the length of the year.

What happens during an El Niño event?

• Trade winds strengthen, causing more upwelling.

• Warm surface waters pool along the coast of South America.

• Australia experiences increased rainfall.

• The thermocline becomes steeper.

What is the effect of La Niña on the Pacific Ocean?

• Weaker trade winds and warmer waters in the east

• Stronger trade winds and increased upwelling

• Increased rainfall in South America

• Flattened thermocline
