Earth's Layers
What is the Earth’s outermost layer called?
Crust
What type of rock is made from layers of sediment?
Sedimentary Rock
What is a Force?
A Push or pull
What process turns magma into igneous rock?
Cooling and solidifying
If Earth were a sandwich, what would the crust be?
The crunchy bread on the outside – the Earth’s crust!)
Which layer of the Earth is the thickest?
What is a fossil?
Preserved remains or traces of plants/animals
Name a force that pulls everything toward the Earth.
Gravity
What rock can form from sediment over time?
Sedimentary Rock
Which rock type would a volcano serve for dinner?
Igneous – because it’s made fresh from magma!
Which layer is made of solid metal and is very hot?
Inner Core
Name one type of rock formed by heat and pressure.
Metamorphic Rock
What kind of force resists motion between two surfaces?
Friction
What do heat and pressure turn sedimentary rock into?
Metamorphic rock
Why don’t fossils have bad breath?
Because they’re millions of years old and don’t talk!)
Name the three main layers of the Earth from outside to inside.
Crust, Mantle, Core
Which type of rock forms from cooled magma or lava?
Igneous
Give two ways a force can affect an object.
Change direction, speed, or shape
What happens to rocks during weathering and erosion?
They break down into sediment
What would happen if you tried to rollerblade on frictionless ground?
You’d slide forever – no friction to stop you!
Why is the inner core solid even though it's extremely hot?
Because of the immense pressure
Explain how fossils are formed in sedimentary rock.
Organism is buried by sediment, pressure builds, remains are preserved in the rock
Which force acts without touching objects and is responsible for things falling?
Gravitation Force (non-contact)
Describe the full cycle of a rock starting from magma.
Magma → Igneous → Sediment → Sedimentary → Metamorphic → Melts → Magma again
You stretch a rubber chicken until it snaps back. What force was at work?
Elastic force
