The topography of the world PPT, the third part: content learning

Plain: It is a vast flat area with low altitude, mostly between 0 and 500 meters above sea level, usually in coastal areas.

Those with an altitude of 0-200 meters are called low plains, and those with an altitude of 200-500 meters are called high plains.

The causes are classified into alluvial plains, marine plains, moraine plains, and glacial plains.

Plateau: The altitude is generally above 1,000 meters. It has a vast area and open terrain. It is bounded by obvious steep slopes. A relatively complete large-area uplifted area is called a plateau.

Mountainous areas: refer to highlands with an altitude of more than 500 meters, with great undulations, steep slopes, deep valleys, and are generally distributed in a vein shape.

A mountainous area is an area where many mountains are located, which is different from a single mountain or range.

Hills: refers to the gently undulating shape of the earth's surface, with an absolute height within 500 meters and a relative height no more than 200 meters, and a slope combination composed of various rock types. The slope is generally gentle, cut and broken, and has no certain direction.

Basin: a basin-shaped terrain surrounded by mountains and plateaus, with plains or hills in the middle;

When a plain is surrounded by mountains, it is a landform type composed of a plain and a hillside facing the plain.
