Savannah and Sam explore the fascinating world of rocks, focusing on how different types of rocks, such as sedimentary, igneous, and metamorphic, form and transform. They discuss the rock cycle, the role of heat and pressure in metamorphic rock formation, and the influence of tectonic plates. The video also highlights the unique characteristics of rocks like gneiss and marble, and encourages viewers to engage with the topic by exploring their own rock collections.

What is the main characteristic of gneiss that suggests it was once a different type of rock?

• Its color

• Its wavy stripes

• Its shiny surface

• Its round shape

What are sedimentary rocks primarily made from?

• Crystallized minerals

• Compressed sediment

• Molten lava

• Solidified magma

How do igneous rocks form?

• By crystallization of minerals

• By cooling of liquid rock

• By compression of sediment

• By evaporation of water

What does the term 'metamorphic' suggest about these rocks?

• They are formed from sediment

• They are formed from lava

• They have undergone a transformation

• They are formed from water

What can cause a rock to become metamorphic?

• High heat and pressure

• Exposure to sunlight

• Erosion by wind

• Freezing temperatures

What are tectonic plates?

• Layers of sediment

• Pieces of Earth's crust that move

• Types of metamorphic rocks

• Large rocks in the ocean

What is foliation in metamorphic rocks?

• Layering due to pressure

• A process of erosion

• A type of igneous rock

• A type of mineral

Which rock can limestone transform into under heat and pressure?

• Granite

• Marble

• Slate

• Schist

What is the rock cycle?

• The cooling of magma into rocks

• The erosion of rocks by wind

• The transformation of rocks from one type to another

• The process of rocks forming from water

Can metamorphic rocks transform into other types of rocks?

• Only into igneous rocks

• Yes, they can become any other type

• Only into sedimentary rocks

• No, they remain the same
