Contiental Drift
What is lava?
Lava is magma that flows out onto Earth's surface.
What are magma chambers?
Magma chambers are reservoirs from which volcanic materials erupt.
What is the strongest evidence for Pangea? Why?
fossil evidence, because it shows literal bones of fossils that match DNA etc.
Explain geology evidence
Rocks, minerals and natural resources on separate continents are consistent with each other and are found in locations that suggest the continents were once joined together.
what is a vent? where is it located?
Openings through which volcanic materials erupt are called vents. They are located near the peak of the mountain.
What is happening during seafloor spreading?
magma from the Earth's mantle rises at mid-ocean ridges, erupts, and cools to form new oceanic crust.
Explain landform evidence
Mountains and other landforms on separate continents seem to be continuous. The only way the landforms could be continuous is if the continents were once combined together as Pangaea.
What are craters?
Craters are bowl-shaped depressions. Forceful explosions may blow out the tops of mountains to form craters.
What is the difference between magma and lava?
Magma is inside the earth and lava is outside of the earth
Explain fossil evidence
There are similar fossils dating to the same time period found on separate continents.
What is a hot spot?
A region of volcanic activity in the middle of a tectonic plate.
Describe the story of Pompeii and how does it relate to volcanoes?
The story of Pompeii is a historical story of a prosperous Roman city that was destroyed in a single day by the eruption of Mount Vesuvius, which buried the city under ash and debris, preserving it for centuries
