The Earth’s crust is not made
up of one piece. It is made from
different pieces or plates. The
plates can move very slowly. The
plates move slowly over the hot
rock below them. This is a map of
Earth’s plates.
Mountains are made by moving
moving plates. The moving crust
slowly pushes the ground up into
tall mountains. A mountain range
is a long line of mountains. The
mountains in a mountain range
were all made at the same time
and in the same way. Many of the
world’s mountain ranges are near
the edges of plates. For example, the Andes is Earth’s longest mountain
range. It is along the edge of the South American Plate. The Himalayas is
Earth’s highest mountain range. It is along the edge of the Indian Plate.
A deep ocean trench is a deep
valley under the ocean. They are
made when one of Earth’s plates
goes under another plate. This
picture shows the Mariana Trench.
This is the deepest ocean trench
on Earth.
