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.
Answer: Plants such as tree cones depend on wildfires in order to pass through a regular life cycle.
Explanation:
Some Tree cones need wildfires to enable them pass through a life cycle because the heat produced melts the substance that covers the pines thereby enabling the pines to open up and spread their seeds.
Wildfires are therefore essential to the continued survival of trees such as these because without wildfires, these trees might never go through the entirety of their life cycle by dispersing seeds and if this continues it would spell doom for the survival of the species.

"Erratics" are large rocks that are not the same as the rock types found in the area and are deposited by the glaciers as they move or melt.
<h3>What are erratics?</h3>
Stones and rocks that were carried by a glacier and then abandoned after the glacier melted are known as glacial erratics.
Some characteristics of erratics are-
- The bedrock where the glacial erratic is deposited has a distinct lithology from the sort of rock that makes up the glacier erratic.
- A sandstone boulder moved by a glacier and placed on top of limestone bedrock would be an example of an erratic.
- Scientists can identify and locate the source outcrop of some erratics because they are made of a particular type of distinguishable rock.
- In order to recreate historical glacier flow directions, the timing of glacier retreat, and even the type of glacier flow, it is helpful to analyze glacial erratics.
- Large boulders, tiny stones, and pebbles can all be erratic. Every erratic is made of a unique sort of rock.
