The process by which water moves from the Earth's surface to the atmosphere is called:

  1. Evaporation

  2. Condensation

  3. Precipitation

  4. Transpiration

  5. Infiltration

Show answer
Correct Option: A
Explanation:

Evaporation is the process by which water moves from the Earth's surface to the atmosphere in the form of water vapor.

The term 'deforestation' refers to:

  1. The clearing of forests

  2. The planting of trees

  3. The management of forests

  4. The study of forests

  5. The conservation of forests

Show answer

The primary cause of acid rain is:

  1. The burning of fossil fuels

  2. The eruption of volcanoes

  3. The decomposition of organic matter

  4. The release of methane from wetlands

  5. The use of fertilizers in agriculture

Show answer
Correct Option: A
Explanation:

The burning of fossil fuels, such as coal and oil, releases sulfur dioxide and nitrogen oxides into the atmosphere, which react with water vapor to form sulfuric acid and nitric acid, leading to acid rain.

Show answer
Correct Option: A
Explanation:

Sustainable development refers to the use of resources in a way that does not harm the environment, allowing for the needs of the present generation to be met without compromising the ability of future generations to meet their own needs.

The process by which plants lose water vapor through their leaves is called:

  1. Photosynthesis

  2. Respiration

  3. Transpiration

  4. Decomposition

  5. Pollination

Show answer
Correct Option: C
Explanation:

Transpiration is the process by which plants lose water vapor through their leaves, which helps to regulate their temperature and transport nutrients.

The term 'biodiversity hotspot' refers to:

  1. A region with a high concentration of biodiversity

  2. A region with a high rate of deforestation
