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.

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
