These are the 2 ways geologists learn about Earths interior
What is direct and indirect evidence?
100
This is the scientists that came up with the theory of continental drift
Who is Alfred Wegner?
100
This is heat transfer through empty space
What is radiation
100
This is the amount of matter in an object
What is mass
100
This is what happens to the density of a fluid when it gets hotter
What is its density decreases
200
This is the main indirect evidence used to learn about Earths interior
What are seismic waves?
200
This is the name of the supercontinent that existed 250million years ago
What is Pangaea
200
This is heat transfer within a material or between materials that are touching
What is conduction?
200
This is the amount of space an object occupies
What is volume
200
This is what happens to the density of a fluid when it’s temperature gets colder
What is it gets more dense
300
This is how temperature and pressure change as you travel fromEarths crust towards its interior
What is they increase?
300
This is evidence based on land features. Explain
What is coastlines and mountain ranges on different continents lined up
300
This isn’t heat transfer by the movement of currents within a fluid
What is convection?
300
This is how you can calculate density of an object
What is mass divide by volume
300
Find the volume of a cube that has a side of 5cm. Use correct units!
What is 75cm^3
400
These are 2 difference between the inner and outer core
What is inner is solid and outer is liquid, inner is hotter and under more pressure than outer
400
This is evidence from fossils. Explain
What is fossils of different plants and animals were found on several different continents that could not have traveled between those continents and could not have existed in those climates
400
These are the 2 layers of earth in which convection can occur
What is mantle (asthenosphere) and outer core?
400
Calculate the density of an object that has a mass of 100 grams and a volume of 20 milliliter. Use correct units!
What is 5 g/ml
400
Find the density of an object with a mass of 1000 grams and a volume of 500cm^3
What is 4g/cm^3
500
This is the main difference between the lithosphere and the asthenosphere
What is lithosphere is rigid and asthenosphere is rigid but can flow
500
This is why Wagner’s theory was rejected by most scientists of his time.
What is he could not explain the forces that push or pull the continents?
500
This is what causes convection currents in the mantle
What is heat from the core and mantle itself.
500
This is how you can compare the density of 2 objects with the same volume. The one with more mass is .....
What is more dense.
500
This is what causes a convection current, and without it the convection current will stop
