Exploring Earth's Systems and Their Interactions

What is a system?

• A single entity that operates independently

• A collection of parts or processes that depend on each other and work together

• A group of unrelated components

• A mechanical tool used for earth studies

What does the hydrosphere include?

• Only the water found underground

• Just the rivers and lakes

• All water and ice on Earth

• Only the oceans and seas

What is the geosphere?

• All the water on Earth

• The layer of air surrounding Earth

• The collection of Earth's landmasses and inner layers

• Only the surface of Earth

What can be found in the biosphere?

• All living things on Earth

• Just bacteria and viruses

• Only plants and fungi

• Only humans and animals

What is the main function of the atmosphere?

• To protect Earth from the sun's ultraviolet radiation

• To create mountains and valleys

• To provide oxygen for cars

• To supply water to the oceans

How do the hydrosphere and atmosphere interact?

• Through the creation of mountains

• When water evaporates and forms clouds

• By the movement of tectonic plates

• Through the process of photosynthesis

What is erosion?

• The movement of water in oceans

• The process of building mountains

• The act of planting trees

• The breakdown of rocks and land over time

How does a volcanic eruption affect Earth's systems?

• It improves air quality

• It only affects the geosphere

• It has no effect on Earth's systems

• It can cause changes in all of Earth's systems

Why is the weather worse on high mountains?

• Because the air is warmer and wetter

• Because of the higher oxygen levels

• Due to the presence of more trees

• Because of the cooler and drier air

How are all of Earth's systems connected?

• Through human activities only

• They are not connected

• By interactions that shape our climate and support life

• Only through the water cycle
