Continental Drift
German geophysicist and meteorologist who first theorized continental drift
Who is Alfred Wegner?
Topographic maps are
What is 2d maps that represent 3d landforms
The 4 layers that make up the earth
What is The Crust, The Mantle, and The Inner and Outer Cores.
The percentage of water on earth that the ocean contains
What is 97%?
The 4th most plentiful element in existence
What is carbon?
The continents that look like they fit together
What is South America and Africa?
Elevation is indicated by
What is a contour line?
The mantle is mainly comprised of
Molten Rock
The percentage of oxygen in the atmosphere created by life in the ocean
What is 70%?
The water cycle is driven by
What is the Sun?
A key part of continental drift theory was the presence of what on multiple separate continents
What is identical fossils?
What does it mean when contour lines are closer together
What is that the slope is steeper?
The outer and inner core are made up of
What is Heavy metals, like Iron, Nickle and Cobalt?
Percentage of species on earth found in the ocean
What is 15%
The place where the most carbon is stored
What is the crust?
The mainstream explanation for fossils of the same kind being found on different continents before continental drift theory
What is that there were once great land bridges connecting all continents?
A contour interval is
What is the vertical distance between 2 lines?
The inner core is roughly the sized of
What is Pluto
The most common cause of islands in the middle of the ocean
What is undersea volcanoes or mountains whose tips stick above water?
Recent global warming is a result of
What is Human activity releasing carbon into the atmosphere at an unnatural rate?
The reason continental drift occurs
What is the tectonic plates being pushed along currents of magma on the surface of the mantle?
To find the distance of the contour interval you must
What is finding the two known elevations subtracting one from the other, and dividing by the number of spaces in-between them?
The reason the inner core remains solid while the outer core and mantle are liquid
What is extreme pressure?
The reason ocean currents exist
What is changing temperatures of the waters, causing them to become more or less dense?
The difference between fast and slow moving carbon
What is fast moving carbon is stored as sugar in plants and slow moving carbon is the carbon that shifts between the atmosphere, crust, and deep ocean.
