Question

How are oases formed?

A. Human made by digging or drilling into the ground
B. Low spots on the surface of the sand
C. Spring water bubbling up to the surface
D.All of the above

Answer 1

C.

Step-by-step explanation:

Why C?

It's because, to make bubbles, you usually need some form of gas like O2 aka Oxygen to make bubbles. Like if you blow into a straw, a straw thats in your dribk, it causes it to bubble up sometimes.

You can eliminate A.

Just because you drill into the ground, it doesnt cause gas. Unless it's to make a factory and causes polution by releaing chemicals into the air, the yes.

Eliminate D.

Because A doesn't seem right, it most likely not be all of them.

For B. I'm not sure

I'm not sure what Low Spots are unless you're talking about those small little holes made in the sand, it was mostly made by crabs

If I'm wrong, let me know. But, I hope this helped you! :)

Answer 2

Step-by-step explanation:

An oasis can be formed by an underground aquifer or river that creates enough pressure for water to seep to the surface, forming the oasis. These aquifers and natural springs allow for life to exist in harsh climates like the desert and are often well known to local herders, farmers, and travelers in the region.
