The video tutorial covers the hydrosphere, focusing on the water cycle, including evaporation, transpiration, condensation, and precipitation. It explains groundwater formation, runoff, and water distribution on Earth. The tutorial also discusses groundwater features like springs and geysers, and highlights the importance of water usage and pollution. The session concludes with a summary and a preview of the next module on surface water.

What is the hydrosphere primarily composed of?

• Only oceans

• All water on Earth, including oceans, glaciers, and freshwater

• Only glaciers and ice caps

• Only freshwater systems

Which process involves plants releasing water vapor into the atmosphere?

• Evaporation

• Condensation

• Precipitation

• Transpiration

What type of precipitation occurs when rain freezes upon contact with a cold surface?

• Sleet

• Snow

• Hail

• Freezing rain

What term describes the ability of soil or rock to allow water to flow through it?

• Porosity

• Infiltration

• Saturation

• Permeability

What is an aquifer?

• A permeable rock layer that stores groundwater

• A type of cloud formation

• A type of precipitation

• A layer of impermeable rock

What is the main difference between porosity and permeability?

• Porosity is the water content, while permeability is the air content.

• Porosity is the temperature of the soil, while permeability is the pressure of water.

• Porosity is the amount of pore space, while permeability is the ease of water flow through those spaces.

• Porosity refers to the size of particles, while permeability refers to the color of soil.

What natural feature is formed when groundwater reaches the Earth's surface?

• A geyser

• A spring

• A sinkhole

• A glacier

What causes geysers to erupt?

• Freezing of rainwater

• Boiling of groundwater due to underground heat

• Cooling of surface water

• Condensation of water vapor

What is karst topography characterized by?

• Flat plains

• Mountainous regions

• Underground caves and sinkholes

• Desert landscapes

What is the primary cause of sinkholes in karst regions?

• Earthquakes

• Erosion by wind

• Collapse of underground caves

• Volcanic activity
