Explain seafloor spreading. Check all of the following that applies: occurs at boundary between the North American plate and the Eurasian plate
forming a raised mid-oceanic ridge.
The magma also spreads outward, forming new ocean floor and new oceanic crust made of basalt
As plates made of oceanic crust pull apart, a crack in the ocean floor appears.
Magma then oozes up from the mantle to fill in the space between the plates
created the Hawaiian Island chain
at a convergent boundary
O convection currents are falling in the mantle below this location.

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
