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.

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
