Which two represent the two facts that lead us to expect Earth to be warming up as a result of human activity be sure to choose two of the statements below?
Human activity is increasing the concentration of carbon dioxide and other greenhouse gases in the atmosphere. Greenhouse gases make Earth warmer than it would be otherwise. Animal deaths due to carbon dioxide poisoning.
Which characteristic of earth explains why Earth has the ozone necessary for an ultraviolet-absorbing stratosphere?
astronomy final shelley
|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 characteristic of earth explains why Earth has the ozone necessary?
The ozone layer is extremely important because ozone gas in the stratosphere absorbs most of the Sun’s harmful ultraviolet (UV) radiation. Because of this, the ozone layer protects life on Earth.
Is Europa in the Sun’s habitable zone?
Europa is located outside the Sun’s habitable zone and yet may be habitable. The Moon is in the habitable zone of the Sun at the same distance as the Earth but is not habitable.
Where is Earth in the habitable zone?
The distance Earth orbits the Sun is just right for water to remain a liquid. This distance from the Sun is called the habitable zone, or the Goldilocks zone.
Are any planets habitable?
A 2015 review concluded that the exoplanets Kepler-62f, Kepler-186f and Kepler-442b were likely the best candidates for being potentially habitable. These are at a distance of 990, 490 and 1,120 light-years away, respectively.
Can Super Earth support life?
According to one hypothesis, super-Earths of about two Earth masses may be conducive to life. The higher surface gravity would lead to a thicker atmosphere, increased surface erosion and hence a flatter topography.
Are there many earths in universe?
Throughout the universe, trapped in the halos of dark matter, there is enough planet-making material to create at least 1,000,000,000,000,000,000,000 more Earth-like planets. A billion trillion of them.
Is Earth a spheroid?
Isaac Newton first proposed that Earth was not perfectly round. Instead, he suggested it was an oblate spheroid—a sphere that is squashed at its poles and swollen at the equator. Our globe, however, is not even a perfect oblate spheroid, because mass is distributed unevenly within the planet.
Is there a full picture of Earth?
No human since has been far enough from Earth to photograph a whole-Earth image such as The Blue Marble, but whole-Earth images have been taken by many uncrewed spacecraft missions.
What color is the real sun?
Is it pitch black in space?
As they left Earth’s atmosphere, they were greeted by the inky darkness of space. Or were they? According to a new study scheduled to be published in The Astrophysical Journal, scientists have determined that outer space isn’t pitch black at all — it’s actually filled with light.
What would happen if solar flare hit Earth?
The most powerful solar storms send coronal mass ejections (CMEs), containing charged particles, into space. If Earth happens to be in the path of a CME, the charged particles can slam into our atmosphere, disrupt satellites in orbit and even cause them to fail, and bathe high-flying airplanes with radiation.
