Fjord
Deep waterways that were forged by glaciers and extend inland from the sea. Fjords have steep cliffs on the sides and are located near the arctic circles.
Fjords were created by glaciers. In the Earth's last ice age, glaciers covered just about everything. Glaciers move very slowly over time, and can greatly alter the landscape once they have moved through an area. This process is called glaciation. Glaciation carves deep valleys. This is why fjords can be thousands of meters deep. Fjords are usually deepest farther inland, where the glacial force was strongest.
