What are glaciers? A glacier is a huge mass of ice that moves slowly over land.
tigry1 [53]

Answer:

What do they look like?

Glaciers look like solid blocks of ice.

What climate do they exist in?

Regions that have high snowfall in winter and cool temperatures in summer.

Where can you find them?

Most of the world's glacial ice is found in Antarctica and Greenland, but glaciers are found on nearly every continent, even Africa.

What do you think we can learn from glaciers?

Glaciers preserve bits of atmosphere from thousands of years ago in these tiny air bubbles, or, deeper within the core, trapped within the ice itself. This is one way scientists know that there have been several Ice Ages. Scientists are also finding that glaciers reveal clues about global warming.

(The last question is unclear to me, so I'm going to take a guess as to what you meant)

Why is sea ice so important?

Arctic sea ice keeps the polar regions cool and helps moderate global climate.

I hope this helps!! :3

Which has a greater biotic potential- humans or mice? Why?
Ganezh [65]
Nice because : Biotic potential is the ability of a population of living species to increase under ideal environmental conditions – sufficient food supply, no predators, and a lack of disease. An organism’s rate of reproduction and the size of each litter are the primary determining factors for biotic potential.

In 2006, scientists found a fossil that seemed to have fish-like scales and four legs. It also had a bone structure in its neck
lianna [129]

Answer:

Option-C

Explanation:

Scientists found a fossil of a fish with four limbs or legs. The fossil was estimated to be around 375 million years old.  

The fossil showed the fins and scales of a fish but they also possess the bones of proto-wrist, shoulders and the elbow.

The presence of these bones can be a clue that the fish evolved the limbs to walk on the land and will later evolve into animals belonging to amphibians, reptiles and mammals. Therefore, the Tiktaalik is considered the missing link of how life evolved from water to land.

Thus, Option-C is correct.
