One of the factors that affects the rate of weathering is exposure to the atmosphere. ... Another factor that affects the rate of weathering is the composition of rock. Rocks are composed of minerals, which are solid substances found within rocks that have their own distinct chemical composition.
Answer:
Number of bacteria required 
Explanation:
Given -
Size of each bacterium
micrometers long
These bacteria are arranged end to end.
The size of chain to be formed is equal to
centimetres
Let us say that in forming a chain of
centimetres nearly X number of individual bacterium are required.
hence, number of bacterium required to form
centimetres chain can be represented as

Number of bacteria required

The wild salmon has the capability of reproducing quickly, which makes wild salmon a renewable resource.
<h3>What do you mean by Renewable resources?</h3>
Renewable resources may be defined as those resources that are not exhausted and deliver endless energy.
Wild salmon can be taken as one of the chief sources of food that provides energy. This form of energy may lead to renewable energy because it is endless, as the reproduction rate of wild salmon is fast with large clutch size.
Therefore, the wild salmon has the capability of reproducing quickly, which makes wild salmon a renewable resource.

In mid-ocean ridge areas, ocean water is cycled through the crust because of the high heat flow in the area. Water in the rock is heated over the magmas, rising up and drawing in cold water from the sides. This process is occurring all over the world, and is the primary means for maintaining ocean salinity in a relatively constant range over the long term, as elements in the sea water when it is heated react with the rocks. There is so much water flow, cumulatively over the entire world, that this process basically buffers ocean chemistry.
Obviously large increases or decreases in salinity can and do occur in isolated basins that do not have free exchange with the open oceans.
