Earth Science SOL Review 2

Front

What is Karst topography?

Back

Karst topography is a landscape formed from the dissolution of soluble rocks, such as limestone, leading to features like underground caverns, sinkholes, and unique surface formations.

Front

Where in Virginia is Karst topography primarily found?

Back

Karst topography is primarily found in the Valley and Ridge region of Virginia.

Front

What determines whether a star becomes a Giant or Supergiant star after the Main Sequence stage?

Back

The mass of the star determines whether it will become a Giant star or a Supergiant star after the Main Sequence stage.

Front

What is a meander in the context of rivers?

Back

A meander is a curve or bend in a river, often formed by the erosion and deposition of sediment.

Front

What does well-sorted soil indicate about its porosity?

Back

Well-sorted soil has high porosity, meaning it has a uniform particle size that allows water to move through it easily.

Front

Which organism is responsible for increasing oxygen levels in the atmosphere?

Back

Cyanobacteria are responsible for building oxygen levels in the atmosphere through photosynthesis.

Front

Define porosity in soil science.

Back

Porosity is the measure of the void spaces in a material, such as soil, and is expressed as a percentage of the total volume.

Front

What is an aquifer?

Back

An aquifer is a geological formation that can store and transmit water, often tapped for drinking water and irrigation.

Front

Explain the term 'Oxbow Lake'.

Back

An Oxbow Lake is a U-shaped body of water formed when a meander from a river is cut off, creating a lake.

Front

What is the significance of mass in stellar evolution?

Back

Mass is the primary factor that influences a star's life cycle, determining its temperature, luminosity, and eventual fate.
