VIII. Read the text.

Scientists describe the Earth’s composition as follows. The Earth we live on is a rocky slightly bulged at the poles Globe with the radius of 6372 km. The outer shell called the crust comprises only 0.6% of the planet’s volume. The crust with the thickness ranging form 5 to 35 km, is separated from the mantle by a sharp boundary, known as the Moho surface. This layer occurs at the depth of 2900 km and occupies up to 82% of the Earth’s volume. Apparently, the mantle consists of three zones: the upper layer with the depth of about 370 km, the intermediate layer with the depth of approximately 600 km and the lower one, it’s thickness being 1900 km. The innermost layer, the core, is composed mainly of liquid iron and nickel. It is the core that generates magnetic filed of the Earth.

Are the following statements true or false?

1. The mantle occupies up to 0.6% of the Earth’s volume.

2. The Earth consists of three layers.

3. The uppermost layer of the Earth is called the mantle.

4. The crust generates magnetic field of the Earth.
