A because it’s based on the environment and the society
Answer:
A. The area from southern France to Mongolia changed to frozen tundra in winter and semiarid steppe in summer.
Explanation:
- The last glaciers period occurred at the end of the Permian period and took place about 115,000 11,700 years ago. And the appearance of the glacial and the interglacial periods and is referred to as the last ice age and the ice caps of the Sierra Nevada and Rocky mountains and the alps and the baltic peninsular and Patagonia ice sheets in the south.
The atmosphere is important for many reasons. Before we talk about why it is important we should define what the atmosphere is. The atmosphere is the layer of air that surrounds a planet. Earth has an atmosphere that is just right for humans, animals, and plants to live in. The gases in the atmosphere act like a blanket keeping our planet warm plus the atmosphere contains oxygen something we (humans and animals) all need to breathe.
Many planets in our solar system have a atmosphere. Venus for example has such a thick atmosphere most of the sun's energy gets trapped making the surface of Venus 864 degrees Fahrenheit! That is hotter than an oven! Mars also has an atmosphere but it is too thin making the surface of Mars -80 degrees Fahrenheit! Plus the atmospheres of Venus and Mars do not contain the oxygen we all need to breathe.
Our atmosphere allows just enough of the sun's energy back into space so that we do not get to hot like Venus or too cold like Mars. If Earth had no atmosphere, apart from having no air to breathe, the surface of the Earth would be 0 degrees Fahrenheit.
These are just two of the reasons why are atmosphere is important. The atmosphere contains the warmth we all need to survive, the oxygen we all breathe, and carries the rain we all need. Without our atmosphere life as we know it would cease to exist.
In the west, the Atlantic, east, Atlantic is connected to the pacific, and the Arctic is in the both and south. I hope it somewhat helped. Sorry if I didn’t :)
The other stars are far away from us but the sun is close but not to close to us
