Multiple choice

The formation of soil from weathered rock and organic matter is called:

  1. Erosion

  2. Weathering

  3. Pedogenesis

  4. Leaching
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Pedogenesis is the process of soil formation, which involves the physical and chemical weathering of rock, the accumulation of organic matter, and the activity of soil organisms.

Multiple choice

The process by which water evaporates from the Earth's surface, condenses in the atmosphere, and falls back to the Earth as rain or snow is called:

  1. Water cycle

  2. Hydrologic cycle

  3. Precipitation

  4. Evaporation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The water cycle, also known as the hydrologic cycle, is the process by which water evaporates from the Earth's surface, condenses in the atmosphere, and falls back to the Earth as rain or snow.

Multiple choice

The process by which soil is protected from erosion by wind and water is called:

  1. Erosion control

  2. Soil conservation

  3. Land management

  4. Deforestation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Erosion control is the process by which soil is protected from erosion by wind and water, preventing soil loss and degradation.

Multiple choice

What is the term used to describe the process of soil becoming less acidic over time?

  1. Acidification

  2. Alkalization

  3. Neutralization

  4. Salinization
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Alkalization refers to the process of soil becoming less acidic and more alkaline over time, often due to natural processes or human activities such as liming.

Multiple choice

What is the name of the process by which rocks are broken down into smaller pieces?

  1. Weathering

  2. Erosion

  3. Deposition

  4. Metamorphism
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Weathering is the process by which rocks are broken down into smaller pieces by the action of wind, water, and other natural forces.

Multiple choice

What is the term used to describe the phenomenon where air pollution is trapped in a valley or basin due to geographical features?

  1. Inversion

  2. Stagnation

  3. Fumigation

  4. Advection
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Inversion is a meteorological phenomenon where a layer of warm air traps cooler air near the ground, preventing the dispersion of air pollutants. This can lead to high levels of air pollution in valleys or basins.

  3. Deposition

  4. Metamorphism
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Weathering is the process by which rocks are broken down into smaller pieces by the action of water, wind, ice, and other natural forces.

  1. Weathering

  2. Erosion

  3. Deposition

  4. Metamorphism
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Deposition is the process by which sediments are deposited in a new location by the action of water, wind, ice, or gravity.
