Final answer:
The reason why fossils of rocks that were made out of the same magma can be found in different parts of the world, oceans away from each other, is due to plate tectonics.
Step-by-step explanation:
The reason why fossils of rocks that were made out of the same magma can be found in different parts of the world, oceans away from each other, is due to plate tectonics.
Plate tectonics is the theory that explains the movement of the Earth's lithosphere, which is divided into several large plates. These plates can move apart or collide with each other. When two plates collide, one can be subducted, or pushed beneath the other, into the mantle. As a result, rocks from the subducted plate can be carried deep into the Earth and eventually brought back to the surface through volcanic activity in a different location. This is how rocks made from the same magma can be found in different parts of the world.
For example, the Himalayan mountains were formed by the collision of the Indian and Eurasian plates. Rocks that were once part of the Indian plate can now be found in the Himalayas.
