What was the name of the single continent that comprised all of today’s continents, according to tectonic plate theory?
Due to the presence of fossils common to
different continents.
Cracks or fissures in a plate, caused by motion inside the lithosphere.
It states that the surface of the geosphere consists of a rigid layer called the lithosphere, which in turn is
fragmented into plates.
Pangea

How do fossils lead us to believe that the continents used to be joined together?
Due to the presence of fossils common to
different continents.

Describe how these geological features move: oceanic ridges
Tectonic plates meet and collide. One of them sinks below the other, creating deep trenches.
The magma that creates the lithosphere bursts out of them and the plates separate,
creating mountains on the ocean bottom.
Fissures are created in a plate, and this causes earth tremors.
Describe how these geological features move: subduction zones
Tectonic plates meet and collide. One of them sinks below the other, creating deep trenches.
The magma that creates the lithosphere bursts out of them and the plates separate,
creating mountains on the ocean bottom.
Fissures are created in a plate, and this causes earth tremors.

Earthquakes can be predicted and prevented.
True
False
Earthquake damage can be reduced if an emergency action plan is developed.
True
False
Before an earthquake, we should all pay attention to the weather forecast.
True
False
All volcanoes erupt in the same way.
True
False
Explain how each type of rock is produced: Igneous rock
They are produced by erosion caused by agents such as wind and water.
They are produced when igneous or sedimentary rock changes after it has been
formed.
They are produced when lava cools down.
Explain how each type of rock is produced: Sedimentary rock
They are produced by erosion caused by agents such as wind and water.
They are produced when igneous or sedimentary rock changes after it has been
formed.
They are produced when lava cools down.
Explain how each type of rock is produced: Metamorphic rock
They are produced by erosion caused by agents such as wind and water.
They are produced when igneous or sedimentary rock changes after it has been
formed.
They are produced when lava cools down.
