Answer:
Plate tectonics is like a giant puzzle with pieces that slowly move around on Earth's surface. When two of these pieces, called tectonic plates, bump into each other, they can push the ground up to form mountains. This is how the Himalayas were made! On the other hand, when plates move apart, they create gaps that can fill with water, forming ocean basins like the Atlantic Ocean. So, the slow but powerful movement of tectonic plates is what shapes many of the mountains and oceans we see on our planet.
