Explanation:
As human population increases the rate of consumption of resources also increases. Economists postulates that available resources with which to satisfy our unlimited wants as a population is highly limited.
- Increase in population leads to an increasing pressure on available resources such as freshwater, land, air, energy e.t.c.
- Increasing population easily leads to deforestation. Deforestation is the loss of forest. Forest trees are used in construction of houses and industries. Forests also takes up space and they might have to be plundered to make way for new buildings. Eventually, the forest will be lost.
- Decrease in standard of living: increasing population will lead to a low standard of living. Resources meant to accommodate a certain number of people will no longer be sufficient for them.
- High poverty rate; if population continues to rise, the rate of poverty will increase too. There will be limited resources to cater for the well being of the populace as a whole.

Answer:
Your answer should be a. There is an increase in the number of collisions between particles and the walls of the container.
Answer:
Both physical and chemical weathering, along with erosion, can change Earth's surface as physical weathering allows breakdown of rock into smaller pieces, these pieces can be move from one place to another through water, wind or ice (erosion), and when the smaller pieces will settle down at a place, rain water can react with the soil or smaller rock pieces to form rock minerals.
For example: Running water, wind, and rapid heating/cooling allows the rocks to break down into smaller pieces or grains (physical weathering), then the small grains are transported and settled away from the source area through wind or river (erosion), and at the end the surface area exposed to air for chemical weathering.
