Earth Science SOL Review 2

What does well-sorted soil indicate about its porosity?

• Well-sorted soil has low porosity, meaning it retains water and does not drain well.

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

• Well-sorted soil has variable porosity, which makes it difficult for water to penetrate.

• Well-sorted soil has no porosity, indicating it is compacted and dense.

What is the significance of mass in stellar evolution?

• Mass determines a star's temperature and luminosity, but not its fate.

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

• Mass has no significant impact on a star's evolution.

• Mass only affects the star's size and not its life cycle.

Describe the process of photosynthesis in cyanobacteria.

• Cyanobacteria convert sunlight, carbon dioxide, and water into glucose and oxygen, significantly contributing to atmospheric oxygen.

• Cyanobacteria use sunlight to produce carbon dioxide and water, which are then converted into glucose.

• Cyanobacteria perform photosynthesis by absorbing nutrients from the soil and releasing nitrogen into the atmosphere.

• Cyanobacteria convert glucose and oxygen into sunlight and carbon dioxide through a process called respiration.

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

• Cyanobacteria

• Algae

• Fungi

• Protozoa

What is Karst topography?

• A landscape formed from the erosion of mountains.

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

• A type of desert landscape characterized by sand dunes.

• A landscape formed by volcanic activity, resulting in craters and lava flows.

What is an aquifer?

• A type of fish found in freshwater

• A geological formation that can store and transmit water, often tapped for drinking water and irrigation.

• A method of water purification

• A device used to measure water levels

Define porosity in soil science.

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

• Porosity refers to the density of soil particles in a given volume.

• Porosity is the ability of soil to retain water without any voids.

• Porosity is the measure of soil's ability to support plant growth.

Explain the term 'Oxbow Lake'.

• A circular pond formed by rainfall.

• A U-shaped body of water formed when a meander from a river is cut off, creating a lake.

• A type of lake that is always dry.

• A lake that is formed by volcanic activity.

What is a meander in the context of rivers?

• A straight section of a river

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

• A type of fish found in rivers

• A man-made structure to control river flow

What is the difference between the Coastal Plain and the Valley and Ridge regions in Virginia?

• The Coastal Plain is characterized by flat, low-lying areas and sedimentary deposits, while the Valley and Ridge region features folded mountains and valleys formed by tectonic activity.

• The Coastal Plain is known for its mountainous terrain, while the Valley and Ridge region is flat and low-lying.

• The Coastal Plain has a dry climate, whereas the Valley and Ridge region experiences heavy rainfall.

• The Coastal Plain is primarily urbanized, while the Valley and Ridge region is mostly agricultural.
