How does the atmosphere protect life on Earth Check all that apply?

The atmosphere also protects living things on Earth from the sun’s harmful ultraviolet radiation. The atmosphere also helps to sustain life of Earth. It provides oxygen for humans and animals to breathe, and carbon dioxide for plants.

How does oxygen protect life on Earth?

The more oxygen accumulated in the atmosphere, the larger became the protective ozone layer (formed from oxygen in the atmosphere). Ozone helped protect developing life from the harmful effects of the Sun’s ultraviolet radiation. Then other life forms such as sponges, worms, and other organisms came to be.

How does Earth’s atmosphere support and protect life?

The Earth’s atmosphere protects and sustains the planet’s inhabitants by providing warmth and absorbing harmful solar rays. In addition to containing the oxygen and carbon dioxide, which living things need to survive, the atmosphere traps the sun’s energy and wards off many of the dangers of space.

What are three ways the atmosphere protects life on Earth?

Three Ways That the Atmosphere Helps Living Things Survive on Earth

  • Protection. The atmosphere blocks out harmful rays from the sun.
  • Water. The Earth’s atmosphere contains water.
  • Oxygen and Carbon Dioxide. Life on Earth needs the atmosphere to breath.
  • Other Benefits. The atmosphere contains a large amount of nitrogen.

How does the atmosphere help the Earth?

Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface. And it warms our planet and keeps temperatures habitable for our living Earth.

Why is Earth so special?

Earth is special because it is an ocean planet. Water covers 70 percent of Earth’s surface. Earth’s atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe. The atmosphere also protects us from incoming meteoroids, most of which break up before they can hit the surface.

How did life appear on Earth?

The earliest known life-forms are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 Gya (billion years ago), relatively soon after the oceans formed 4.41 Gya, and not long after the formation of the Earth 4.54 Gya.

What was on Earth before dinosaurs?

At the time all Earth’s land made up a single continent, Pangea. The age immediately prior to the dinosaurs was called the Permian. Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo.
