Tectonic Plates
What kind of activity can happen at tectonic plate boundaries?
Volcanoes erupting, mountains forming, earthquakes
The gases from cars contribute to this effect.
What is Global warming / the greenhouse effect?
An imprint in the rocks of something that existed long ago
What is a fossil?
Three sections of the Earth
What are the Core, Mantle, Crust?
Comes up through a volcano
What is lava or magma?
Two plates colliding to cause mountains
What is Converging?
This is in the drinking water, even at some school, and is toxic when consumed
What is Lead?
What can scientists learn from Fossils?
How life has changed
True or false: the amount of rock on earth is changing
A circle on Earth with lots of volcanoes
What is the ring of fire?
Two plates going away from one another and causing magma to come up and make young sea floor
What is Diverging?
A material that will never decompose. Maryland banned restaurants from using this October 1st.
What is styrofoam?
How are rocks containing fossils formed?
The material that makes up the mantle layer of the Earth. It is solid but gets so hot it cycles like a liquid as it heats and cools.
What is magma?
Something in the ocean that volcanoes can form
What are islands?
Two plates rubbing together to cause an earthquake
What is a transform plate boundary?
Organizations like bikemore are pushing for this in Baltimore
What is the complete street ordinance?
Would rock layers closer to the surface or farther down contain fossils of organisms that evolved more recetnly?
Are the oldest rock layers farther down or closer to the surface?
Farther down
One plate going underneath another to cause a volcano
What is Subduction?
The cycling (heating and cooling) of magma that cause tectonic plates to move
What is convection?
An area, like places in Baltimore, where people don't have access to fresh, healthy food
What is a Food Desert
What is superposition?
The idea that younger rock layers form on top of older layers
The reason that the magma in the mantle layer rises and sinks as it is heated and cooled
What is density? (warm things are less dense than cool things)
A place on the earth that is so warm it can cause a volcano even when it's not at a tectonic plate boundary
What is a Hot Spot?
