Question 1

Formed through the cooling and solidification og magma/lava

Answer 1

Igneous rocks or magmatic rocks

Question 2

What are the 2 types of Igneous rocks? Differentiate.

Answer 2

Intrusive - Formed from solidification of magma below the earth’s surface

Chemical - formed when dissolved materials precipitate from solution
Organic - build-up of plant or animal debris

Question 5

Subjected to heat and pressure and from existing parent rock in the process called metamorphism

Answer 5

Metamorphic rocks

Question 6

2 types of metamorphic rocks

Answer 6

Foliated - through pressure due to compression of rocks that create bonds called foliation
Non foliated - has no foliation or bands
