Which human activity is a major contributor to deforestation and habitat loss?

  1. Sustainable forestry

  2. Urbanization

  3. Organic farming

  4. Renewable energy development


Correct Option: B
Explanation:

Urbanization involves the conversion of natural areas into built-up environments, leading to the loss of forests and other habitats.

What is the term used to describe the introduction of non-native species into an ecosystem?

  1. Endangered species

  2. Invasive species

  3. Native species

  4. Threatened species


Correct Option: B
Explanation:

Invasive species are non-native species that have been introduced to an ecosystem and cause harm to native species and ecosystems.

Which natural disaster is known for causing extensive damage to coastal areas due to high winds and storm surges?

  1. Earthquake

  2. Volcanic eruption

  3. Tornado

  4. Hurricane


Correct Option: D
Explanation:

Hurricanes are tropical cyclones that form over warm ocean waters and bring strong winds, heavy rainfall, and storm surges, causing significant damage to coastal areas.

What is the term used to describe the process of converting natural ecosystems into agricultural land?

  1. Reforestation

  2. Afforestation

  3. Deforestation

  4. Conservation


Correct Option: C
Explanation:

Deforestation involves the clearing of forests for various purposes, such as agriculture, urbanization, or mining.

Which human activity is a major contributor to climate change and global warming?

  1. Recycling

  2. Renewable energy use

  3. Organic farming

  4. Fossil fuel burning


Correct Option: D
Explanation:

Fossil fuel burning releases greenhouse gases into the atmosphere, contributing to climate change and global warming.

What is the term used to describe the process of restoring degraded ecosystems to their natural state?

  1. Conservation

  2. Reforestation

  3. Afforestation

  4. Preservation


Correct Option:
Explanation:

Restoration involves the active process of repairing and restoring damaged ecosystems to their original condition.

Which natural disaster is known for causing sudden and violent shaking of the ground due to the movement of tectonic plates?

  1. Flood

  2. Drought

  3. Earthquake

  4. Landslide


Correct Option: C
Explanation:

Earthquakes are caused by the sudden release of energy below the Earth's surface, resulting in ground shaking and potential damage to structures.

What is the term used to describe the process of planting trees in areas that have been cleared or degraded?

  1. Reforestation

  2. Afforestation

  3. Conservation

  4. Preservation


Correct Option: A
Explanation:

Reforestation involves planting trees in areas that were once forested but have been cleared or degraded.

Which human activity is a major contributor to water pollution and eutrophication?

  1. Organic farming

  2. Sustainable forestry

  3. Industrial waste disposal

  4. Renewable energy development


Correct Option: C
Explanation:

Industrial waste disposal, particularly the discharge of untreated or poorly treated wastewater, can lead to water pollution and eutrophication.

What is the term used to describe the process of protecting and managing natural resources for future generations?

  1. Conservation

  2. Preservation

  3. Restoration

  4. Afforestation


Correct Option: A
Explanation:

Conservation involves the sustainable use and management of natural resources to ensure their availability for future generations.

Which natural disaster is known for causing prolonged periods of abnormally low rainfall, leading to water shortages and drought conditions?

  1. Flood

  2. Earthquake

  3. Drought

  4. Landslide


Correct Option: C
Explanation:

Droughts are characterized by a prolonged period of below-average precipitation, leading to water shortages and adverse effects on ecosystems and agriculture.

What is the term used to describe the process of planting trees in areas that have never been forested before?

  1. Reforestation

  2. Afforestation

  3. Conservation

  4. Preservation


Correct Option: B
Explanation:

Afforestation involves planting trees in areas that have never been forested, typically for the purpose of creating new forests or improving degraded land.

Which human activity is a major contributor to air pollution and respiratory health issues?

  1. Organic farming

  2. Renewable energy development

  3. Sustainable forestry

  4. Fossil fuel burning


Correct Option: D
Explanation:

Fossil fuel burning, particularly in vehicles and power plants, releases harmful pollutants into the air, contributing to air pollution and respiratory health issues.

What is the term used to describe the process of protecting and maintaining natural areas in their natural state?

  1. Conservation

  2. Preservation

  3. Restoration

  4. Afforestation


Correct Option: B
Explanation:

Preservation involves protecting and maintaining natural areas in their natural state, often through legal or regulatory mechanisms.

Which natural disaster is known for causing rapid and destructive movement of soil, rock, and debris down a slope?

  1. Flood

  2. Earthquake

  3. Drought

  4. Landslide


Correct Option: D
Explanation:

Landslides occur when soil, rock, and debris move down a slope, often triggered by factors such as heavy rainfall, earthquakes, or human activities.
