1st Semester Exam Review- Int Sci

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the apparent deflection of moving objects (like air and water) caused by the rotation of the Earth. In the southern hemisphere, this effect causes water to move counterclockwise.

Front

What scale do scientists use to measure earthquake magnitude?

Back

The moment magnitude scale is the most commonly used scale today to express the magnitude of an earthquake.

Front

Where is sediment usually deposited by a stream?

Back

Sediment is typically deposited at locations where the stream decreases in velocity.

Front

What effect does acid rain have on marble and limestone?

Back

Acid rain chemically dissolves and weakens building materials like marble and limestone.

Front

Under what conditions will water infiltrate surface material?

Back

Water will infiltrate surface material if the material is permeable and unsaturated.

Front

Define sedimentation.

Back

Sedimentation is the process by which sediment settles out of a fluid, such as water or air, and accumulates in layers.

Front

What is permeability in geology?

Back

Permeability is the ability of a material (like soil or rock) to allow fluids to pass through it.

Front

Explain the difference between weathering and erosion.

Back

Weathering is the breakdown of rocks and minerals at the Earth's surface, while erosion is the movement of those materials from one location to another.

Front

What is the role of groundwater in the water cycle?

Back

Groundwater plays a crucial role in the water cycle by replenishing surface water bodies and providing water for plants and ecosystems.

Front

What is the significance of the moment magnitude scale?

Back

The moment magnitude scale provides a more accurate measure of an earthquake's size, especially for larger quakes, compared to the Richter scale.
