2. What is continental drift?
Continental drift is the movement of the earths continents
which appear to drift across the ocean and pull apart from
each other.
The theory was rejected originally by most because the
idea of continental drift sounded impossible.

3. What is the evidence for
continental drift?
If the continents moved closer then they would fit together like a jigsaw
puzzle and was once called Pangea.
Living animals in largely separated lands have similarities like India and
Madagascar have similar mammals even though they are far apart from
each other.
Fossils have been found on either of an ocean.

4. How do plates move?
Because of the heat in the inner core of our earth, it causes
molten rock in the mantle layer to move.
It moves in a pattern called a conventional cell that forms
when warn material rises, cools, and eventually sink down.
As the cool material sinks down, it is warmed and rises again.

5. What is the structure of the earth?
Earth has an outer solid crust, a mantle, a liquid
outer core and a solid inner core.
The structure of the earth can be defined in two
ways; mechanically, it can be divided into
lithosphere, asthenosphere, mesospheric mantle,
outer core, and inner core.
