What are the two main levels in the relief of the earth?

THE LITHOSPHERE AND ASTHENOSPHERE The major relief features of the Earth—its continents and ocean basins—were created by the movements of plates on the surface of the Earth..

What are the major relief features?

 The physical shape or surface of the Earth is referred to as relief features or landforms of the Earth. Depending up on their elevation and shape they are called mountains, plateaus, or plains.  Major landforms are formed by Earth movements associated with the movements of crustal plates.

How are landforms useful to us?

Landforms, particularly volcanoes, are key sources of geothermal energy and so landforms, and the areas surrounding them, are often harnessed for electricity and hot water production. Another renewable energy source, wind power, can be harnessed using farms built in elevated areas.

Is a volcano an internal or external force?

DEFINING INTERNAL & EXTERNAL FORCES • Internal processes take place within/inside the earth’s surface. For example: plate tectonics, volcanic formations, earthquakes, etc. External processes take place outside the earth’s surface. For example: floods, avalanches, tornadoes, etc.

Relief or orographic rain is formed when air is forced to cool when it rises over relief features in the landscape such as hills or mountains. As it rises it cools, condenses and forms rain. The highest rainfall totals of over 1,600 mm per year occur in the mountain areas along the west coast.

How physical features are formed?

Constructive forces cause physical features on Earth’s surface known as landforms to grow. Crustal deformation—when crust compresses, pulls apart, or slides past other crust—results in hills, valleys, and other landforms. … Sediments are deposited to form landforms, such as deltas.

What is Earth’s relief?

The Earth’s crust is not flat. It forms the mountains, valleys, basins and plains that make up the Earth’s relief. • The Earth’s relief is always changing because of the action of internal and external forces.
