Streamlike movements of water that occur at or near the surface are called surface currents. So logically, a deep current are streamlike movements of water that flow very slowly along the ocean floor.

As you go deeper and deeper the layers will start to get hotter and thicker.

sounds like erosionA2. This describes freeze-thaw spalling of rocks.
New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition.

The further down, the older the rock. The law of superposition.
