An insect can have one of three types of change in its life. A metamorphosis describes how insects change. Some insects do not go through a change. Instead, the young look like small versions of adults. The only change between young and mature is size. Other types of insects go through a change in physical appearance. There are two types of this type of change. Some insects change only slightly during their change. This type is called incomplete metamorphosis. Other types of insects go through a major change. They don't look at all like the adult when they are born. This type of change is called complete metamorphosis. Occurs in the most primitive insects. Newborn insect looks like a tiny version of the adult. Incomplete Three stages: egg, nymph, and adult. Young, called nymphs, usually similar to adult. Growth occurs during the nymph stage.

What is it called when an insect goes through a major change and does not look anything like it did when it was born?

When a stream or river slows down, it starts dropping its sediments. Larger sediments are dropped in steep areas. Some smaller sediments can still be carried by a slow moving stream or river. Smaller sediments are dropped as the slope becomes less steep. Alluvial Fans In arid regions, a mountain stream may flow onto flatter land. The stream comes to a stop rapidly. The deposits form an alluvial fan. Deposition also occurs when a stream or river empties into a large body of still water. In this case, a delta forms. A delta is shaped like a triangle. It spreads out into the body of water.

Are larger sediments dropped in steeper or less steep areas than smaller sediments in the same stream?

Static electricity is like a teeter-totter. What happens if a teeter-totter is balanced? Correct! It does not move. What about when its not balanced? Yes, it will now begin to move. Charges move when they are not balanced. Charges can build up by friction. Maybe you rub your feet on a wool mat or carpet. Rubber soled shoes readily gain charges. The wool carpet easily gives up charges. The two items become unbalanced. One item has a positive charge. The other has a negative charge. The difference in charge is called static electricity. Just like the teeter-totter, something is going to move. Positive charges build up on the mat. Negative charges build up on you.
Charges can move when they are unbalanced by what?
