Why did families have more children per family in the past?

Biology
1 answer:
Sloan [31]4 years ago
8 0

Answer:

Explanation:

In the past, women had five or six children on average, though many babies died soon after birth or in their infancy. For example, in the eighteenth century in France, half of all children died before age ten, and only one-third reached adulthood. Parents had lots of children to ensure that at least some of them survived. Today, child mortality is much lower and in many countries the death of a child is a rare event.

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
