Which statement explains how mantle plumes produce hotspot volcanoes? a
Mantle plumes push through weak zones of the crust, emerging at Earth’s surface in a plume-shape in areas that are not necessarily the boundaries of tectonic plates.
b
Mantle plumes consist of a molten mix of rock that is much hotter and less dense than surrounding rock and so rises through the mantle.
c
Mantle plumes are formed when tectonic plates move over hotspots in the mantle.
d
Mantle plumes originate near the mantle core boundary, where there is a sharp thermal gradient.

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

ill try to . no promises tho.
