Answer:
Oceanic, Seafloor Spreading, Submarine Volcanic, Rift Valleys, Great african
Explanation:
DIVERGENT PLATE MARGIN (Also known as a constructive boundary or an extensional boundary)
Here two plates moves __away__________from each other. Molten rock, or magma, immediately rises to fill any possible gap and forms new <u>oceanic</u> crust. When this happens underwater, it is described as <u>seafloor spreading</u>. Huge underwater <u>submarine volcanic</u> ranges are formed from magma coming up from the mantle. Over time these submarine volcanoes may become large enough to reach the surface .eg. Iceland in the North Atlantic Ocean.
Where plates move apart on land, <u>rift valleys</u> are formed. An example of this is the <u>Great African</u> Rift Valley.
Extrusive igneous rocks are formed by cooling lava. Since
the temperature gradient between lava and Earth’s atmosphere is very big,
cooling is very rapid. The second option is deemed true, which also means the
third option is false. Foliations occur only in metamorphic rocks, deeming the
forth option false. Since extrusive igneous rocks are formed at the surface of
the Earth, there would be no confining pressure, which means the first option
is false.
Answer:
Rising glaciation in the northern hemisphere which accounted for most of the rise in sea level, ice sheets that covered masses of water, and climate change.
