The rocks found at the bottom of a river smooth and flat because those are collides with each other.
Explanation:
At the bottom of the river, the rocks which are found are very smooth and the shape of these rocks are flat because the rocks at the bottom collide with each other.
This results in the chipping off parts of the rocks and this results in the surface of the rock to become smooth and becoming flat. Moreover the sand found at the bottom acts as a sand paper creating resistance and smooth-ens the rocks at the bottom of the river.
Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.
What is Abrasion?Abrasion is the process of rubbing or scraping away a material, by rubbing against a rough surface or causing friction. This type of mechanical weathering can be brought about by a variety of things, including wind, water, snow, and human action. Rock, metal, plastic and wood are some of the materials that may be subject to abrasion.
This may result in material loss and modification of the appearance and texture of the surface. Natural features such as the smoothness of river boulders or the roundness of pebbles on a beach can also be the result of friction. Sandblasting, grinding and polishing are some examples of industrial abrasive applications.
Therefore, Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.

Explain why the accidental and intentional introduction of new pests is likely to be an ongoing problem for future agriculture, and include possible approaches to solving the problem.
The introduction of pests in a new geographic region may have devastating consequences on crop yields. Invasive pest species often don't have natural predators or exhibit higher adaptive fitness.
Invasive species represent an important subject of concern in agriculture because they have the potential to drastically reduce crop yields.
Generally, invasive pest species don't have natural predators or exhibit higher adaptive fitness compared to well-established natural pest species.
In consequence, these species (invasive species) may cause considerable harm to crops.
