Exploring Earth's Spheres: The Geosphere and Hydrosphere

Which of the following are Earth's spheres and how do they interact with each other?

• Atmosphere, Hydrosphere, Lithosphere, and Biosphere; they interact through various cycles and processes.

• Atmosphere, Hydrosphere, and Stratosphere; they interact through gravitational forces.

• Lithosphere, Biosphere, and Asthenosphere; they interact through tectonic movements.

• Hydrosphere, Atmosphere, and Magnetosphere; they interact through magnetic fields.

What is the main composition of the mantle?

• Silicate minerals

• Iron

• Carbon

• Water

Which layer of the Geosphere is made up of solid iron and nickel?

• The inner core.

• The outer core.

• The mantle.

• The crust.

Caves are natural underground spaces. How are they formed?

• By erosion of rock, often by water

• By volcanic activity

• By human excavation

• By meteor impacts

The Hydrosphere is defined as:

• The layer of gases surrounding Earth

• The solid outer section of Earth

• All the water on Earth's surface, including oceans, lakes, and rivers

• The part of Earth that supports life

What percentage of Earth's water is made up of oceans?

• 97%

• 50%

• 75%

• 85%

Where is most of the freshwater on Earth found?

• Glaciers and ice caps

• Rivers and lakes

• Underground aquifers

• Atmosphere

Deposition in the context of the hydrosphere refers to:

• The process of eroding soil and rock

• The accumulation of sediments in a new location

• The evaporation of water from surfaces

• The melting of ice into water

How can groundwater be accessed?

• Through wells

• By digging trenches

• Using rainwater harvesting

• Through evaporation
