Question Answer
Which characteristic of Earth explains why we have an ultraviolet-absorbing stratosphere? the existence of photosynthetic life
Which two factors are critical to the existence of the carbon dioxide (CO2) cycle on Earth? plate tectonics and liquid water oceans

Which correctly lists three greenhouse gases?

The primary greenhouse gases in the Earth’s atmosphere are carbon dioxide, methane, water vapor, and nitrous oxide. Greenhouse Effect: The ability of gases in the atmosphere to absorb heat from the Earth is called the greenhouse effect.

Which of these is the most common greenhouse gas released by outgassing?

Carbon dioxide (CO2)

What is the main reason mountaintops are so cold?

What is the main reason mountaintops are so cold? Mountaintops are above much of the greenhouse gas in the atmosphere. Light gases such as hydrogen move faster than heavier gases and escape from Earth’s gravitational field.

Where is most of the CO2 that has Outgassed from Earth’s volcanoes?

Calculate the Price

What is the longest-lasting internal heat source responsible for geological activity? radioactive decay
What causes the release of oxygen into Earth’s atmosphere? photosynthesis
Where is most of the CO2 that has outgassed from Earth’s volcanoes? locked up rocks

What causes the release of oxygen into Earth’s atmosphere?

The answer is tiny organisms known as cyanobacteria, or blue-green algae. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen. “What it looks like is that oxygen was first produced somewhere around 2.7 billion to 2.8 billon years ago.

Which terrestrial world has the most atmosphere?

Venus

Which planet can get the coldest?

Uranus

How hot could the earth get?

around 60 degrees Fahrenheit

How cold would Earth get without the sun?

For us on earth, it is a source of life. Even in Antarctica, the coldest place on our planet, temperatures seldom drop below minus 50°C. Without the sun’s radiation, the temperature would be anywhere near the absolute zero of minus 273°C. Life would have never continued nor even have come into existence.

What would happen if carbon disappeared?

If there were an interruption in the carbon cycle, life on Earth as we know it would be in danger of being disrupted. Without carbon dioxide, the plants would not do as well, and potentially die, creating a problem for all the animals on the planet, Since they have to breathe oxygen to live.

What will happen if pollution doesn’t stop?

If air pollution is not controlled, by 2030 the air will become so poisonous that it will be necessary to use an oxygen kit to breathe easily. Rising air pollution will also lead to premature aging. Human exposure to air toxins will increase to a great extent if air pollution is not controlled.

Is our air quality getting worse?

After decades of improving air quality, Carnegie Mellon researchers found that pollution levels are rising across America. A key driver has been the Trump Administration’s all-out assault on environmental regulations.
