What is earth
structure ?
The structure of the earth is divided into four
major components. Each layer has a unique
chemical composition, physical state, and can
impact life on Earth's surface.
Parts of earth that
forms the centre
The core is the centre of the
earth and is made up of two
parts: the liquid outer core and
solid inner core.
What is earth crust
made of?
From mud and clay to diamonds and coal, Earth's
crust is composed of igneous, metamorphic, and
sedimentary rocks. The most abundant rocks in the
crust are igneous, which are formed by the cooling
of magma. Earth's crust is rich in igneous rocks
such as granite and basalt.
What is continental
drift?
Continental drift is the hypothesis that the
Earth's continents have moved over geologic
time relative to each other, thus appearing to
have "drifted" across the ocean bed
