With some types of criticism, it is intended as help or advise, and with others it’s intended to make someone else look or feel bad.
Example: Billy was attempting a handstand on a ladder. Suzy told him it was a bad idea, and that he should get down. This is an example of helpful criticism, because Suzy did not want Billy to get hurt.
Suzy bought a new sweater. Billy told her it was ugly and he would never be seen in public wearing it. This is poorly delivered criticism because it sounded cruel. Billy might have been trying to give helpful advice, but it sounded mean.
Fossils are the remains of plants and animals that have been preserved for millennia in stones under the Earth's surface. They contain the long chapters of the history of our Earth. Fossils tell us what the earth looked like many millions of years ago, what kind of animals and plants lived on its surface and how it was changing. Fossils show us a history of over a billion years old.
From the fossil from a dry, mountainous area we can conclude that the area was once underwater and over time the soil has risen as result of continental drift and uplift. So, a mountain was once the bottom of a prehistoric ocean or sea.
