Something we observe to be similar over and over again.
Particles that are cooled are..
Slow.
Examples of conduction.
Ironing clothes, warming up you hands, bare feet on snow.
Why did Wagner think the continents were connected?
Fossils of animals who couldn't swim across oceans were found on different continents.
How fast do the plates move each year?
Depends where you are.
The place two plates meet.
Plate boundry.
Particles that are hot are.....
Fast.
Conduction happens due to..
Heat transfer through matter, substances need to touch.
Why couldn't the plant fossil survive in
Antarctica?
They were tropical plates and needed warm weather to survive.
Why do volcanoes form at oceanic plates.
Water melts the magma.
Sudden shaking of Earth's surface.
Earthquake.
Hot particles are farther apart and less...
Convection makes things move upperward or spin, why?
The hooter it is it rises up, when it cools it falls. This is due to density.
The mountains matched up like...
Puzzle pieces and made up from the same type of rock.
Oceanic and continental plates form what landform.
Volcanoes.
Why are earthquakes from.
Built up tension from plates not sliding smoothly.
Cold particles are closer together an more...
Dense.
Radiation happens when......
Energy travels in waves.
What happened when the plates and mantle between South America and Africa make them spread?
Convection currents rise up due to heat (less dense), turn at the surface and cool (more dense) when they drop. This pulls the plates and mantle apart.
Continental plates form what landmass?
Mountain ranges.
What is the earth's crust made of?
Hard solid rock.
Particles move due to different..
Density.
Example of convection.
Air ballon.
Why did they know the fossils and the Mesosaurus and the Lystrosaurus couldn't swim across oceans?
The Lystrosaurus didn't have webbed feet and long tails. The Mesosaurus was a good simmer in lakes and small fresh water areas, but still couldn't swim across super large bodies of water.
What happens when the plates and mantle collide?
One goes under (more denser one) And the other forms a landmass.
