Question

A tectonic plate applies a downward force onto the asthenosphere, which lies beneath the plate. According to Newton's 3rd Law, which can be described as the law of action-reaction,

the asthenosphere applies a force of equal magnitude upward onto the tectonic plate.
the asthenosphere applies a force of double magnitude downward as well.
the asthenosphere applies a force of double magnitude upward onto the tectonic plate.
the asthenosphere applies a force of equal magnitude downward as well.

Answer 1

The correct answer for the question that is being presented above is this one: "the asthenosphere applies a force of equal magnitude upward onto the tectonic plate."According to Newton's 3rd Law, which can be described asthe law of action-reaction, the asthenosphere applies a force of equal magnitude upward onto the tectonic plate.
