• a. They are formed from the cooling of magma.

• b. They are often formed in layers or beds.

• c. They are primarily composed of minerals like quartz and feldspar.

• d. They undergo changes due to heat and pressure.

What type of rock forms from the cooling and solidification of magma or lava?

• a. Sedimentary

• b. Metamorphic

• c. Igneous

• d. Fossiliferous

What type of rock is a marble rock?

• a. Sedimentary

• b. Metamorphic

• c. Igneous

• d. None of the above

What is the type of rock that are formed from pre-existing rocks or pieces of once-living organisms ?

• Igneous Rock

• Sedimentary rock

• Molten rock

• Metamorphic rock

What are the three main types of rocks?

• Sedimentary, volcanic, and crystalline

• Metamorphic, volcanic, and sedimentary

• Igneous, sedimentary, and metamorphic

• Igneous, volcanic, and sedimentary

How are igneous rocks formed?

• Through the solidification and cooling of magma or lava.

• Through the evaporation of water.

• Through erosion and weathering of existing rocks.

• By the compression of sedimentary rocks.

Explain the concept of rock cycle.

• The rock cycle involves only one type of rock

• The rock cycle is a continuous process of rock formation, breakdown, and reformation involving igneous, sedimentary, and metamorphic rocks.

• The rock cycle is a linear process with no recycling of rocks

• The rock cycle does not involve any natural processes

How are metamorphic rocks formed?

• By volcanic activity

• By erosion and weathering

• Heat and pressure acting on existing rocks

• By sedimentation and compaction

Water erosion are caused by water usually common in the sea, rivers. That caused an island separated like picture in the left. What is the name of the partial rocks or land that is shown?

• a. Sea rocks

• b. Sea stacks

• c. Small island

• d. Sea cliffs
