Biosphere, Atmosphere, Geosphere, and Hydrosphere Flashcards
What is the biosphere?
The biosphere is the global sum of all ecosystems, encompassing all living organisms and their interactions with the environment.
True or False: The atmosphere contains only oxygen and nitrogen.
False: The atmosphere contains a mixture of gases, including oxygen, nitrogen, carbon dioxide, and others.
Fill in the blank: The ________ is the layer of the Earth that consists of rocks, minerals, and landforms.
geosphere
What are the four major components of the Earth’s system?
The four major components are the biosphere, atmosphere, geosphere, and hydrosphere.
Which component of the Earth system includes all bodies of water?
The hydrosphere includes all bodies of water.
Multiple Choice: Which gas is the most abundant in the atmosphere? A) Oxygen B) Carbon Dioxide C) Nitrogen D) Argon
C) Nitrogen
What role does the biosphere play in the carbon cycle?
The biosphere acts as a carbon sink, absorbing carbon dioxide during photosynthesis and releasing it through respiration.
True or False: The hydrosphere is only composed of liquid water.
False: The hydrosphere includes liquid water, ice, and water vapor.
What is the primary source of energy for the biosphere?
The primary source of energy for the biosphere is sunlight.
Fill in the blank: The ________ is responsible for weather and climate on Earth.
atmosphere
What is the main difference between the geosphere and the hydrosphere?
The geosphere is composed of solid Earth materials, while the hydrosphere consists of all water in various forms.
Multiple Choice: Which layer of the atmosphere is closest to the Earth’s surface? A) Stratosphere B) Troposphere C) Mesosphere D) Thermosphere
B) Troposphere
What is the significance of the ozone layer in the atmosphere?
The ozone layer protects living organisms by absorbing the majority of the Sun’s harmful ultraviolet radiation.
True or False: The geosphere includes all living organisms.
False: The geosphere includes non-living Earth materials, while the biosphere includes living organisms.
What is the function of the hydrosphere in the Earth’s climate system?
The hydrosphere regulates temperature and weather patterns through the storage and movement of water.
Fill in the blank: The ________ is composed of the Earth’s crust, mantle, and core.
geosphere
Which component of the Earth’s system can significantly impact human health?
The atmosphere can significantly impact human health through air quality and pollution.
Multiple Choice: Which of the following is NOT a part of the hydrosphere? A) Lakes B) Rivers C) Mountains D) Oceans
C) Mountains
What is an ecosystem?
An ecosystem is a community of living organisms interacting with each other and their physical environment.
True or False: The biosphere is only found on land.
False: The biosphere exists in both terrestrial and aquatic environments.
What is the process of transpiration?
Transpiration is the process by which water is absorbed by plants and released as water vapor into the atmosphere.
Fill in the blank: The ________ interacts with the biosphere by providing essential nutrients for life.
geosphere
What is the primary cause of atmospheric circulation?
Atmospheric circulation is primarily caused by the uneven heating of the Earth’s surface by the Sun.
Multiple Choice: Which layer of the geosphere is liquid? A) Crust B) Mantle C) Outer Core D) Inner Core
C) Outer Core
