Science Fall Final Exam

Front

What are underwater volcanic mountains?

Back

Underwater volcanic mountains are mountains formed by volcanic activity beneath the ocean, often creating islands like the Hawaiian Islands.

Front

Who proposed the theory of seafloor spreading?

Back

Harry Hess proposed the theory of seafloor spreading, which explains how new oceanic crust is formed at mid-ocean ridges.

Front

What is abrasion in the context of glacial movement?

Back

Abrasion is the process where a glacier scrapes the underlying rock, wearing it away like sandpaper due to the sediments and rocks frozen in the ice.

Front

Define a tsunami.

Back

A tsunami is a large ocean wave typically caused by underwater earthquakes or volcanic eruptions.

Front

What are stalactites?

Back

Stalactites are mineral formations that hang from the ceilings of caves, formed by the dripping of mineral-rich water.

Front

What are fault-block mountains?

Back

Fault-block mountains are formed through faulting, where blocks of the Earth's crust are lifted or tilted.

Front

What are upwarped mountains?

Back

Upwarped mountains are formed when the Earth's crust is pushed upwards due to tectonic forces.

Front

What is the difference between stalactites and stalagmites?

Back

Stalactites hang from the ceiling of caves, while stalagmites grow from the ground up.

Front

What is the process of weathering?

Back

Weathering is the breaking down of rocks and minerals through natural processes such as wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind or water.
