NEED HELP ASAP: List two ways in which the atmosphere would be impacted in the absence of the biosphere. Use complete sentences.

Answers

Answer:

If there would be no biosphere on earth the atmosphere would be quite different. There would be no oxygen to support because oxygen is liberated by plants in photosynthesis so no plants means no oxygen. The earth would be a planet without life just like Venus and Mars. Therefore, no organism would be surviving in the world.

There would be no  negligible green house effect and global warming since it is all created due to activities of men.The earth's atmosphere would be much cleaner and with lesser amount of CO2 and O2 but no organism would be there to use them.

Hope it help!

There would be more carbon dioxide, which would eventually burn away the ozone layer, as well as no oxygen, and all animal and plant life would perish.

What is biosphere?

The biosphere is basically comprised up of the areas of the Earth where life can be found.

The biosphere encompasses all the things from the deepest tree root systems to the dark environment of ocean trenches, including lush rainforests, and high mountaintops. Earth is described by scientists in terms of spheres.

Because it is all of life, the biosphere is as important as life itself. Earth would be a lifeless planet like Mars or Venus without the biosphere. Human insecurity grows as natural resources are depleted.

The biosphere is the zone that contains all living things. The biosphere requires the lithosphere, hydrosphere, and atmosphere to exist. There would be no life on Earth if these three spheres did not exist.

Thus, this way, the atmosphere would be impacted in the absence of the biosphere.

Which of the following BEST explains how scientists are able to determine the
structure of Earth's interior?
1) Scientists gather indirect evidence using seismic waves (Earthquakes) along with what is visible at Earth's surface.
2)Drilling deep within the Earth.
3)By cutting into other terrestrial planets.
4) Our modern knowledge of the Earth's interior is just a guess that many scientists have accepted.

Answers

Answer:

I think number 1 is the answer.

Scientists gather indirect evidence using seismic waves (Earthquakes) along with what is visible at Earth's surface. The correct option is 1.

What are seismic waves?

Seismic waves are caused by sudden movement of materials within the Earth, such as fault slip during an earthquake.

Seismic waves generated by earthquakes or explosions can travel through the Earth's interior, revealing information about the properties of the rocks and other materials they pass through.

In addition to seismic data, scientists use other indirect methods such as magnetic and gravitational field studies, as well as analyses of rocks and minerals found at or near the surface.

Scientists collect indirect evidence by observing seismic waves (Earthquakes) as well as what is visible on the Earth's surface.

Thus, the correct option is 1.
