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).
Answer:
True.
Explanation:
Igneous rocks are formed by the solidification of the magma and can be called in different ways, depending on the composition and the location where the magma has cooled and solidified to form them. In that case, igneous rocks can be intrusive or extrusive.
They are considered intrusive when the magma cools and solidifies inside the earth, like granite, for example.
They are considered extrusive when the magma cools and solidifies on the earth's surface, such as basalt, for example.
Answer:
When weathering breaks down solid rocks into smaller pieces it creates soil.
