The document discusses the solid part of the Earth, known as rocks and minerals. It defines minerals as naturally occurring inorganic solids with definite compositions and structures, while rocks are solid masses composed of minerals. The document outlines different types of rocks, including sedimentary rocks formed from compacted sediments, igneous rocks formed from cooled magma either underground or above ground, and metamorphic rocks formed from other rocks exposed to heat and pressure. It also briefly explains the Earth's internal structure and the rock cycle by which rocks are continuously changed over geological time.

3. Minerals and Rocks
●
Mineral: A mineral is a naturally occurring
inorganic solid that has a definite chemical
composition and crystalline structure.
Rock: A rock is a solid mass formed by
●
natural mineral.
4. The properties of a mineral
●
Properties: Are hardness, lustre,
colour, streak, transparency, cleavage,
magnetims.
5. Types of rocks
Types of rocks: there are
sedimentary rocks, igneous rocks,
plutunic rocks.
7. Igneous rocks
Igneous rocks: Are formed when
magma cools down. It is divided in
two parts: intrusive (plutonic):The
magma cools slowly inside the
earth,and the second part is
extrusive (volcanic) rocks are when
the magma cools down quickly on the
surface.
