<span>These are the three most common types of stresses that occur at different types of plate boundaries.
Compression- convergent boundaries
Tension- divergent boundaries
Shear- transform boundaries
Therefore, Compression, or compressing stress, is the major type of stress that occurs at convergent plate boundaries.</span>
Answer:
The exchange of heat when heat is transferred to a fluid, such as air or water.
Answer:
Option (3)
Explanation:
Unconformity is defined as the gaps in the sequence of geological rocks. It is a geological contact that marks the boundary between the different types of rocks. In simple words, they are also known as the time of non-deposition. These unconformities have great significance in the field of geology. They are of 4 types, namely-
(1) Angular unconformity- The sedimentary rocks are initially formed and deposited in an area, after that the area is tilted and erosion takes place. Now, the new sediments are deposited forming an angle, which is commonly known as an angular unconformity.
(2) Non-conformity- When the sedimentary rocks are deposited over the igneous or metamorphic rocks, then it is known as the non-conformity.
(3) Para conformity- When the sedimentary rocks are deposited parallel to the ground surface, and absence of erosion activity, then these surface appears to be a normal (simple) bedding plane. This is known as the para conformity.
(4) Disconformity- When the sedimentary rocks are formed and undergoes erosion, then new sedimentary rocks are deposited over this and diminishes the unconformity. This forms a discontinuity.
Thus, the unconformity arises due to both erosion and lack of rock deposition.
Hence, the correct answer is option (3).
Answer:
it means that something does not allow fluids to pass through
Calcitonin, secreted from the thyroid, and parathyroid hormone. Calcitonin lowers the blood calcium levels, PTH increases it.
