The video tutorial explains minerals as solid, naturally occurring substances with a fixed chemical structure, providing examples like quartz and gold. It then describes rocks as composed of various compounds and introduces the three major types: igneous, metamorphic, and sedimentary. Igneous rocks form from cooled magma, metamorphic rocks from heat or pressure, and sedimentary rocks from accumulated sediment. The rock cycle is a continuous process where rocks transition between types, influenced by environmental factors.

What characteristic is common to all minerals?

• They are always liquid.

• They are made from animal products.

• They have a fixed chemical structure.

• They are organic.

Which type of rock is formed from cooled magma?

• Limestone

• Sedimentary

• Igneous

• Metamorphic

How are metamorphic rocks typically formed?

• By evaporation of water

• By cooling of lava

• By heat and pressure

• By accumulation of sediment

What process leads to the formation of sedimentary rocks?

• Compaction of sediment

• Cooling of magma

• Crystallization of lava

• Melting of minerals

What is a key feature of the rock cycle?

• It only involves igneous rocks.

• It is a continuous cycle of change.

• It follows a strict order.

• It occurs over a few years.
