What type of rock is formed from cooled magma or lava?
Answer: Igneous
Igneous rocks form when molten rock (magma below surface, lava above) cools and solidifies.
Which layer of the Earth is composed of liquid iron and nickel?
Answer: Outer core
The outer core is a liquid layer of iron and nickel that generates Earth's magnetic field.
What drives the movement of tectonic plates?
Answer: Convection currents in the mantle
Heat from Earth's interior creates convection currents in the mantle that push and pull plates.
What is weathering?
Answer: The breakdown of rocks by physical, chemical, or biological processes
Weathering breaks down rocks in place, while erosion transports the broken material.
What is the rock cycle?
Answer: The continuous process of rocks transforming between igneous, sedimentary, and metamorphic types
The rock cycle describes how rocks change from one type to another through geological processes over time.
What geological feature forms at a convergent plate boundary?
Answer: Mountain ranges or deep ocean trenches
When plates collide, they can form mountains (continent-continent) or trenches (oceanic-oceanic or oceanic-continental).
