Answer:Please find answers below.
Explanation:
1. Since the rock had different sediments with some of its layers containing marine fossils, then it is a Sedimentary rock which can be either shale, limestone or sandstone.
2.We can say the rock was formed the same way a sedimentary roc is formed . This happens when agents of erosion and weathering ( air, water) disintegrate a rock and carries the sediments from the source area ( in this case from the marine area)to another area usually referred to as area of deposition which over time accumulates and solidify to form a layered rock with marine fossils.
3. A sedimentary rock can either transform to an igneous rock or a metamorphic rock
From Sedimentary to Metamorphic--------> Metamorphic rocks are formed when rocks change their form which is due to pressure and temperature build up in the rocks. Now, when a sedimentary rock exerts pressure and heat within its structured layer, it can lead to a change in its structure forming a metamorphic rock.
From Sedimentary to Igneous Rock----->Igneous rocks are formed from molten magma. Now when there is a volcanic eruption around an area with sedimentary rocks, it melts the rocks and changes thier form and on cooling the rocks transforms to Igneous rock.
