The Earth's 4 Spheres Flashcards
What are the four spheres of the earth?
Land, Water, Living Things, and Air
What’s the specific term for Land?
Geosphere or Lithosphere
What’s the specific term for Water?
Hydrosphere
What’s the specific term for Living Things?
Biosphere
What’s the specific term for Air?
Atmosphere
What is the most prominent feature of hydrosphere?
The Global Ocean
What is the living component of the Earth?
Biosphere
What are the two components of the atmosphere?
The Major Components and The Variable Components
What components that includes the gaseous compound nitrogen and oxygen. It provides the air that people breathe and can trap infrared radiation to keep the Earth warm?
The Major Components
What Components that includes water vapor and aerosols which is experienced on Earth through interaction of the atmosphere, the hydrosphere, and the geosphere?
The Variable Components
It is needed for cloud formation and for trapping the heat of the Earth?
Water Vapor
What serves as condensation nuclei for water vapor and can absorb, reflect, and scatter incoming solar radiation?
Aerosols
What is another variable component of the atmosphere that protects Earth from harmful ultraviolation of the Sun?
Ozone
What are the four different layers of the Atmosphere?
4 - Troposphere
3 - Stratosphere
2 - Mesosphere
1 - Thermosphere
What is the solid component of the Earth?
Geosphere/Lithosphere
What are the different layers of the Earth?
Crust, Mantle (upper & lower), Core (outer & inner)
It is the outmost layer of the Earth. It is relatively thin that it occupies just about 1% of the earth’s volume?
Crust
It compromises 82% of the Earth’s volume and is divided into upper and lower ______?
Mantle
It is made of solid rocks and together with the crust as the “Lithosphere”.
Upper Mantle
It is the weaker region of semi-solid of plastics as “Asthenosphere”.
Lower Mantle
It is made up of iron-nickel alloy making it very dense and it is into inner/outer _____?
Core
It is responsible for Earth’s magnetic field that protects from the harmful solar winds.
Outer Core
What pressure that exists in the center of the planet.
Inner Core
