Answer:
Intensive family planning.
Explanation:
The varied developments in medicine, increased standard of living, and minimal or no warfare has tremendously increased the earth's population rapidly. Within a span of hundred years, the human population have increased from 1 billion to about 7 billion today.
Over population has become a huge problem to earth and its environment. People need more resources, so there is rapid draining of earth's natural resources. Similarly, people needs homes and places to live, so chunks of forests and jungles are cleared out for agriculture and urbanization. All these human activities are affecting the ecology drastically.
We need to quickly take up measures before it is too late. The most fundamental pratice to reduce overpopulation would be intensive family planning. Every individual should hold responsible to this practice. Family planning is discretionary to oneself, therefore it should be practiced responsibly.
If we can maintain human population, the consumption and emission of pollution would ultimately decrease too. Thereby, the earth would have better air and more green areas.
Answer:
A stream in a bedrock valley located 5000 feet above ultimate base level that is draining a mountainous region in the headwater of a stream system would have a _____.
high gradient, and a narrow and shallow channel with no floodplain
Explanation:
A bedrock valley has no alluvium mantling the bedrock over which it flows. Alluvium (consists of sand, gravel, silt, clay, and gravel, as well as other organic matters) mantlings or coverings are usually developed in the lower part of the river with the formation of floodplains and deltas. They may also be deposited at lakes or river banks. Headwater streams deliver nutrients and other organic materials (e.g. fallen leaves) to downstream regions to sustain downstream aquatic life.
Answer:
The strength of the sun can cause droughts and dry land. Water can cause weathering and erosion (breaking away at land) snow can cause avalanches to break things and land rain can cause floods and and also can cause weathering to break away and make land smaller
