CANYONS
Canyons can be found on land, underwater, and even on other planets. The largest known canyon, the Valles Mariners, is found on Mars. That's an amazing landform! Canyons's take millions of years to form.
Canyons have three main characteristics: a narrow valley, steep sides, and are formed by erosion. Most of the time, canyons are eroded by a water source such as a river or stream. The force of the water tears away at the land and carries layers of rock with it. Eventually it transforms into a canyon. Erosion can occur by wind rain, gravity, or tectonic plate movements.

Australia has some large canyons like Kings Canyon, south west of Alice Springs, NT. The walls of the canyon are over 100 m high, with Kings Creek at the bottom. It is part of the Luritja people's traditional country. Before the arrival of your Europeans in the region, the damp climate at the bottom of the canyon was an important refuge for the Luritja people during droughts.
VALLEYS
A Valley is a common landform. They are found all over the earth, along the ocean floor, and even on other planets! Valleys are formed through a process called erosion. During erosion rock and soil wear down over a long period of time. There are three main types of valleys: river valleys, glacial valleys, and flat-floored valleys.
A river valley is formed by a river. They are the v-shaped and have taller areas of land on either side of the river. A glacial valley is formed by glaciers. They are U-shaped, wide, and deep. These valleys are created by huge sheets of ice that flow down a mountain and carve the sides and floor away. Flat-floored valleys are the most common type of valley. They have eroded the ground for so long they are flat on the bottom.
Valleys are known for fertile soil, animal life, and vegetation. Many ancient civilisations settled in valleys because of its resources. Some well-known valleys are the Nile River Valley in Africa and Valley of the Ten Peaks in Canada.
