Question 1

The Sahara Desert's location on the northern continent of Africa is primarily due to which atmospheric factor?

Accepted Answer

Persistent high-pressure cells near 30° latitude

Question 2

Which term describes the practice of building terraces on hillsides to create flat planting surfaces and reduce soil erosion?

Accepted Answer

Terrace farming

Question 3

Which U.S. geographic region is most known for its karst topography, featuring sinkholes and limestone caves?

Accepted Answer

Central Florida and parts of Tennessee/Kentucky

Answer

Central Florida and the Tennessee-Kentucky area contain extensive karst landscapes formed when slightly acidic groundwater dissolves limestone bedrock, creating sinkholes and cave systems.

Question 4

Accepted Answer
