mantle
crust
Name the structure of planet Earth at D:
inner core
mantle
crust

The Earth's crust is:
molten rock churning beneath the surface
cold, rocky hard outer layer of the Earth
the metal centre of the Earth
What is magma?
explosive gases erupting from a volcano
hot liquid rock beneath the surface of the Earth
where water and lava meet
The mantle is...
the molten rock churning beneath the Earth's crust
rocky, cold, hard outer layer of the Earth
the metal centre of the Earth
The Earth's outer core is...
the molten rock churning beneath the crust
the rocky, cold, hard outer layer of the Earth
the metal centre of the Earth
the liquid layer of metals that flow around the inner core, made of iron and nickel
What are the six major tectonic plates called?
United Kingdom, African, Venezuelan, North American, Australian, Icelandic
African, North American, Australian, Pacific, Eurasian, South American
South American, Eurasian, Pacific, Icelandic, Venezuelan, United Kingdom
North American, Eurasian, Pacific, Icelandic, Venezuelan, United Kingdom
How do tectonic plates move?
...by the force of gravity
...by being pulled by the attraction of the moon
...from the liquid rock churning beneath them
What happens around the ring of fire?
fires rage on the Pacific Ocean
most of the Earth's volcanic eruptions and earthquakes occur here
magma seeps through the fissures (deep cracks) to cause an eruption
What happens when tectonic plates meet?
Nothing
One plate will bend and slide under another; both plates buckle and push the rocky crust upwards; they grind and scrape against each other
One plate will bend and slide under another; both plates buckle and push the rocky crust upwards; they pull apart
One plate will bend and slide under another; they pull apart; they grind and scrape against each other
What is the epicentre of an earthquake?
the part that causes the earthquake
the point on the earth's surface, vertically above the centre of the earthquake
where cracks appear in the land
What is the focus of an earthquake?
It is the location in the Earth where the earthquake starts
where the fissures and faults appear around the epicentre
where cracks appear in the land
What two events are the result of tectonic plates pulling apart?
water floes into the gap and fills it up; volcanic eruptions occur as magma flows out of the fissure
volcanic eruptions occur as magma flows out of the fissure; new rock is formed as the lava cools
new rock is formed as the lava cools; rocks and boulders fall into the fissure and full it up
rocks and boulders fall into the fissure and full it up; water flows into the gap and fills it up
(a) is the highest mountain in the world.
