Answer:
a rise in temperature causes a rock to expand and a decrease in temperature causes a rock to contract.
Explanation:
a rise in temperature causes a rock to expand and a decrease in temperature causes a rock to contract. Also known as frost wedging can cause rocks to physically break apart. Cracks in rocks expand as water seeps in and freezes. water expands as it freezes to become ice
Frequent changes in temperature can cause cracks to form in the rock formation. So the statement is true.
Temperature is an important factor that can affect various geochemical phenomena, including Rock formation. It has been observed that the rocks which are exposed to high temperatures developed increased strength and decreased plasticity.
In the field of geoengineering, various studies are being carried out to study the effect of temperature on Rocks. It is important to study the thermal properties of rocks to understand the phenomenon going on in the crust of the earth.
In high temperatures, the thermal stress of the rocks increases giving rise to multiple cracks on the rock. This weakens the strength of the rock. Similarly, a decrease in temperature would result in the contraction of the rocks and a decrease in the strength of the rock.
Therefore the statement that said that change in temperature causes cracks in a rock formation is true.
