The water table is defined as the upper boundary of the zone of saturation, where the pores in the soil or rock are fully saturated with water.

Multiple choice

Groundwater is replenished by

  1. rocks

  2. pumping

  3. well

  4. rainwater

  3. a non-potable water

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

Groundwater is a vital source of fresh water, as it is naturally filtered through layers of soil and rock, making it generally suitable for human consumption.

Multiple choice

Which option, among the following, defines an aquifer?

  1. Bed rock and rocks restrict the movement of water

  2. Groundwater is stored between layers of hard rock

  3. Sand or soil, which permits the passage of water

  4. Low rainfall area
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An aquifer is an underground layer of water-bearing permeable rock or unconsolidated materials from which groundwater can be extracted.

Multiple choice

The water under the ground is known as

  1. groundwater

  2. aquifer

  3. water table

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

Groundwater is the term used to describe all water found beneath the surface of the earth.

Multiple choice

Freshwater trapped in the soil and bedrock

  1. salt water

  2. surface water

  3. freshwater

  4. groundwater
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Groundwater is water that occupies the pore spaces between soil particles and within rock fractures beneath the Earth's surface. It is a major source of freshwater for many regions.

Multiple choice

  1. ancient

  2. irrigation

  3. contribution

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