Earths system Flashcards
What are the four main components of Earth’s system?
The four main components are the atmosphere, hydrosphere, lithosphere, and biosphere.
True or False: The atmosphere is the layer of gases surrounding the Earth.
True.
Fill in the blank: The ________ is the solid outer part of the Earth.
lithosphere
What is the hydrosphere?
The hydrosphere includes all the water on Earth, including oceans, rivers, lakes, and groundwater.
Multiple Choice: Which component of Earth’s system is primarily responsible for weather?
Atmosphere
What role does the biosphere play in Earth’s system?
The biosphere consists of all living organisms and their interactions with the environment.
True or False: The lithosphere includes the Earth’s crust and the upper mantle.
True.
Fill in the blank: The ________ is essential for regulating Earth’s temperature.
atmosphere
What is the primary source of energy for the Earth’s system?
The Sun.
Multiple Choice: Which of the following is NOT a component of Earth’s system?
Asthenosphere
What is the significance of the water cycle within the hydrosphere?
The water cycle is crucial for distributing water, regulating climate, and supporting life.
True or False: The lithosphere is composed mainly of water.
False.
Fill in the blank: The ________ is where life exists on Earth.
biosphere
What are greenhouse gases and their role in the atmosphere?
Greenhouse gases trap heat in the atmosphere, helping to maintain the Earth’s temperature.
Multiple Choice: Which layer of the atmosphere is closest to the Earth’s surface?
Troposphere
What is the relationship between the atmosphere and the hydrosphere?
The atmosphere interacts with the hydrosphere through processes like evaporation and precipitation.
True or False: The biosphere can exist without the lithosphere.
False.
Fill in the blank: ________ is the process by which water vapor becomes liquid water.
Condensation
What is a system in the context of Earth’s components?
A system is a set of interacting components that work together as a whole.
Multiple Choice: Which of the following processes is part of the rock cycle?
Erosion
What is the impact of human activities on the Earth’s system?
Human activities can lead to climate change, pollution, and habitat destruction.
True or False: The biosphere is only found on land.
False.
Fill in the blank: The ________ is the largest reservoir of freshwater on Earth.
glaciers
What is the significance of plate tectonics in the lithosphere?
Plate tectonics explain the movement of Earth’s crust and the formation of mountains, earthquakes, and volcanoes.
Multiple Choice: Which component of the Earth’s system is responsible for photosynthesis?
Biosphere
How does the atmosphere protect life on Earth?
The atmosphere filters harmful solar radiation and helps regulate temperature.
