Earth climate has a lot to do with weathering of rocks. When the temperature is high, there is more weathering of rocks, when the temperature is low, weathering of rocks is less.
<u>Explanation:</u>
Studying the rocks which is the field of Geology is done to study about the minerals, and other useful substances which tells a lot about the climate of the planet Earth.
The increase in the weathering of the rocks tells about the high temperature of the planet Earth. In the previous times, when there was less of carbon dioxide in the atmosphere, the temperature used to be low, there was less weathering of the rocks.

Answer:
Antibiotics inhibit enzymes specific to bacteria and have no effect on virally encoded enzymes
Explanation:
The specificity of the antibiotics to inhibits some bacterial enzymes is one of the major reasons why antibiotic do not affect viruses.In addition antibiotics are designed to have a significant destructive effects on the mechanisms of biochemical reactions in bacteria and its physiology, e,g on the cells walls,( inhibiting the formation of peptydoglycans) on certain organelles e,g ribisomes (inhibiting protein synthesis) and on the DNA(disrupting replication). The virus physiology is different from bacteria, therefore the design of antibiotics will nor affect these same mechanisms in viruses, thus no specificity for the antibiotic to act on in virus
