Answer: It can take millions of years for a rift valley to form.

A valley is carved by a glacier then - There did not appear to be any hospitable camping areas in the valley because the mountains dropped precipitously to the valley floor.

The correct option is A.

A stream valley that has been glaciated, also known as a glacial trough, often has a characteristic catenary, or U-shaped, cross section. U-shaped valleys are typical of mountain glaciers and may be seen all over the world.

In contrast to the V-shaped valleys formed by rivers, valley glaciers carve U-shaped valleys. When the temperature on Earth cools, glaciers develop and start to move downhill. They frequently choose the shortest route and settle in the small, V-shaped valleys that originally belonged to rivers.

A collection of different valleys with high walls and flat bottoms are carved by glaciers. It is a difficult terrain to explore and extremely dangerous for camping.

The complete question is:

Which of the following statements would be true for a valley carved by a glacier?

A. There did not appear to be any hospitable camping areas in the valley because the mountains dropped precipitously to the valley floor.

B. We hardly had a break on the hike across the valley: as soon as we reached the bottom, it was time to begin the climb up to the other side.

C. Frank hiked three miles straight across the valley before beginning a gentle climb up the mountain on the other side.

D. The Snake River winds through Hells Canyon, North America's deepest.

Name the reason why languages become extinct.​
lesya [120]

Answer:

From a state of endangerment, many languages become extinct. When the speakers of a language are exterminated as what happened to Tasmanians in the 19th century, several languages suddenly died. Another reason for the extinction is the pressure exerted on a community to incorporate with a more powerful or larger group.
