Weather Things: Climate Change

The video discusses the impermanence of Earth's climate, highlighting natural causes like solar intensity, Earth's orbit, and volcanic activity. It also examines human influences, such as urbanization, agriculture, and aerosols, which alter local climates and albedo. The video concludes with a look at cloud seeding as a method of weather modification, noting its legal and environmental implications.

Which of the following is NOT a natural cause of climate change?

• Volcanic eruptions

• Changes in Earth's axial tilt

• Variations in Earth's orbit

• Airplane condensation trails

How do airplane condensation trails affect the climate?

• They increase the Earth's albedo

• They decrease the amount of aerosols

• They cause more volcanic eruptions

• They create cirrus clouds that cool the Earth

What is the term used to describe the amount of sunlight reflected by the Earth?

• Condensation

• Transpiration

• Albedo

• Evaporation

Which human activity is known to create urban heat islands?

• Deforestation

• Large-scale agriculture

• Construction of cities with asphalt and concrete

• Cloud seeding

How does transpiration from crops affect local climate?

• It reduces the amount of rainfall

• It decreases the amount of sunlight

• It increases the local temperature

• It adds moisture to the air, creating a wetter climate

What is the primary water source for agriculture in arid regions?

• Aquifers

• Rainwater

• Lakes

• Rivers

What is cloud seeding primarily used for?

• Increasing the Earth's albedo

• Enhancing precipitation from clouds

• Reducing urban heat islands

• Preventing volcanic eruptions
