What part of the atmosphere protects the earth from radiation?
Does atmosphere protect radiation?
Gases in Earth’s atmosphere form a protective layer Nitrogen, oxygen and ozone molecules in the upper atmosphere and stratosphere absorb ultraviolet light from the Sun, providing a shield that prevents this radiation from passing to the Earth’s surface.
How can you protect the atmosphere?

- Use long-lasting light bulbs.
- Plant a tree.
What is the range of atmosphere?
It extends from Earth’s surface to an average height of about 12 km (7.5 mi; 39,000 ft), although this altitude varies from about 9 km (5.6 mi; 30,000 ft) at the geographic poles to 17 km (11 mi; 56,000 ft) at the Equator, with some variation due to weather.
What plant produces the most oxygen on Earth?
Why is oxygen so important for life on Earth?
Oxygen plays a critical role in respiration, the energy-producing chemistry that drives the metabolisms of most living things. We humans, along with many other creatures, need oxygen in the air we breathe to stay alive. Oxygen is generated during photosynthesis by plants and many types of microbes.
Is oxygen more important than water?
Adequate dissolved oxygen is necessary for good water quality. Oxygen is a necessary element to all forms of life. Biologically speaking, however, the level of oxygen is a much more important measure of water quality than feacal coliform.
Why is liquid important for life?
Water. Liquid water is an essential requirement for life on Earth because it functions as a solvent. It is capable of dissolving substances and enabling key chemical reactions in animal, plant and microbial cells. Its chemical and physical properties allow it to dissolve more substances than most other liquids.
Why is water so rare in the universe?
But water isn’t that rare in the cosmos. Water is made of hydrogen and oxygen. Hydrogen is by far the most abundant element, and Oxygen is the third most abundant. Number two is helium, which doesn’t react chemically, so water is really common.
What is the most important prerequisite for life?
The abundance of liquid water at the surface of the earth and water vapor in the atmosphere, reduces temperature fluctuations. ..
What characteristics of Earth allow liquid water to exist?
The Earth’s atmospheric pressure and relatively stable temperatures make liquid water possible. Our orbit within the sun’s habitable zone prevents…
What are the 3 state of water?
Pure water is tasteless, odorless, and colorless. Water can occur in three states: solid (ice), liquid, or gas (vapor). Solid water—ice is frozen water.
What are the 3 processes where water enters the atmosphere?
Water and the atmosphere Water enters the atmosphere through evaporation, transpiration, excretion and sublimation: Transpiration is the loss of water from plants (via their leaves)
Where is Earth’s water present?
Earth’s water is (almost) everywhere: above the Earth in the air and clouds, on the surface of the Earth in rivers, oceans, ice, plants, in living organisms, and inside the Earth in the top few miles of the ground.
