The answer is D, noble gases are stable.
Answer:
It absorbs less heat per molecule than the greenhouse gases methane or nitrous oxide, but it's more abundant and it stays in the atmosphere much longer. Increases in atmospheric carbon dioxide are responsible for about two-thirds of the total energy imbalance that is causing Earth's temperature to rise
Answer:
It is difficult to cross.
Explanation:
The Sahara desert is a vast region about the size of the continental United States that is extremely dry and barren. The lack of water resources in the desert make the land unsuitable for agriculture and human population.
As a result, the Sahara acts as a giant natural wall both economically, culturally, and socially since relations between states to the north and south of the desert are difficult.
Vast, circular to elliptical dark-colored areas on the moon called maria represent <u>very large impact</u><u> craters </u><u>filled with </u><u>basaltic lava</u>.
As the brightest and largest object in our night sky, the Moon softens the axial wobble of our home planet, making it a more habitable planet, resulting in a relatively stable climate. It also causes the tides, creating rhythms that have guided humans for thousands of years.
Without the Moon, a day on Earth would only last 6 to 12 hours. A year can be more than 1000 days. This is because the earth's rotation slows down over time thanks to gravity (or the gravitational pull of the moon). Without it, the days would fly by.
