Answer:
A rock's exposure to the weathering elements and its surface area can affect its rate of weathering. Rocks that are constantly bombarded by running water, wind, and other erosion agents, will weather more quickly. Rocks that have a large surface area exposed to these agents will also weather more quickly.
Explanation:
Properties of the Parent Rock ;
- The mineralogy and structure of a rock affects it’s susceptibility to weathering.
- Different minerals weather at different rates. Mafic silicates like olivine and pyroxene tend to weather much faster than felsic minerals like quartz and feldspar. Different minerals show different degrees of solubility in water in that some minerals dissolve much more readily than others. Water dissolves calcite more readily than it does feldspar, so calcite is considered to be more soluble than feldspar.
-
A rock’s structure also affects its susceptibility to weathering. Massive rocks like granite generally to not contain planes of weakness whereas layered sedimentary rocks have bedding planes that can be easily pulled apart and infiltrated by water. Weathering therefore occurs more slowly in granite than in layered sedimentary rocks.

Answer:
The cells in a population die at a constant rate
Explanation:
Microbial death is the loss of the ability of microbes to reproduce and survive in an environment. When a given microbial population is given a treatment, the microbial cells die at a constant rate. Microbial death rate is not dependent on the specie and nor on the antimicrobial agent.
Therefore, the microbial cells in a population does not die at once but die at a constant logarithmic rate; the cells decreases exponentially as nutrients decreases and waste product increases.
For example, if 500,000 microbes are treated or in a nutrient depleted environment and 50,000 microbes is left after 1 minute, by the next minute under the same condition 5,000 microbial cells will be left and this pattern will continue, this explains exponential decrease
