Answers
Answer:
Atmosphere - The atmosphere of Earth is the layer of gases, commonly known as air, retained by Earth's gravity, surrounding the planet Earth and forming its planetary atmosphere.
Biosphere - The biosphere, also known as the ecosphere, is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth. The biosphere is virtually a closed system with regards to matter, with minimal inputs and outputs.
Stratosphere - The stratosphere is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere.
Exosphere - The exosphere is a thin, atmosphere-like volume surrounding a planet or natural satellite where molecules are gravitationally bound to that body, but where the density is so low that the molecules are essentially collisionless.
Answer:
Exosphere-The exosphere is the outermost layer of the Earth's atmosphere.
Stratosphere- The stratosphere is a layer of Earth's atmosphere. It is the second layer of the atmosphere as you go upward.
Biosphere - The biosphere is a narrow zone of the earth where land, water, air interact with each other to support life.
Atmosphere-The atmosphere is the blanket of gases which surrounds Earth
