Answer: Option A and D can best describe conglomerate sedimentary rock.
Explanation: Conglomerate sedimentary rock is a clastic sedimentary rock that contains large round clasts. The round shape is as a result of several turning from some distance by running water or waves during weathering. From the explanation of the conglomerate sedimentary rock we can say option "A" is true because the rock has large clasts coming together to form the rock, option "D" is also true because of the round edge characteristics / properties of the clast.
Answer: Option (A) and (C)
Explanation: In case of slow sea floor spreading, the magma within the crust doesn't get proper way to exert the force upward because of its slower rate of spreading. Due to this, rifting occurs along the mid oceanic ridge.
Due to continuous rifting, it forms a valley known as the rift valley. This rift valley lacks in ridge and is comparatively smooth compared to a fast spreading sea floor, in which the topography appears to be rough and ridges are formed.
Thus, the statements that are true are option (A) and (C).
