What is a divergent boundary?
A region where the rigid plates are moving apart.
100
Why do Earthquakes occur?
When rock underground suddenly breaks along a fault.
100
What is a volcano?
A volcano is a landform where molten rock erupts through the surface of the planet.
100
What are the 3 groups of rocks?
Igneous Sedimentary Metamorphic
200
What is a convergent boundary?
A boundary in which two plates move together.
200
What causes earthquakes?
Earthquakes are vibrations inside the Earth that follow the release of energy that has built up inside rocks.
200
What is the difference between lava and magma?
Magma is liquid rock inside a volcano. Lava is liquid rock that flows out of a volcano.
200
What is an Igneous Rock?
A major group of rocks. All igneous rocks develop when molten rock cools and hardens.
300
What is a transform boundary?
A boundary in which 2 plates slide past each other without creating or destroying lithosphere.
300
Do all earthquakes produce earthquake waves?
Yes
300
What are the 3 layers Earth is made of?
Core Crust Mantle
300
What is Sedimentary Rock?
Form when older rocks weather. The pieces of older rock are carried down stream to form clastic rocks which include shale, mud-stone and siltstone.
400
Mid-ocean ridges usually form where tectonic plates are?
Diverging
400
Where do earthquakes occur?
Earthquake Zones
400
When magma erupts what is it called?
Lava
400
What is Metamorphic Rock?
The third group of rocks. Metamorphic rocks form when igneous, sedimentary and metamorphic rocks recrystallize without melting within the Earth.
500
Most volcanoes occur on ?
Convergent Boundaries
500
How are earthquakes recorded?
Seismographs
500
What is the Ring of Fire?
Over half of the world’s volcanoes arise in a belt around the Pacific Ocean
500
How do rocks in the 3 families change?
Due to tectonic plate movement as crustal plates collide, move apart or slip past each other.
