mass wasting changes the surface of the earth quickly
A shiny surface reflects 'more' light than a matt surface.
False
if they didn't you couldn't see them
True, that is a source of friction.
A variable does and must change, but you can only have one variable, otherwise the experiment becomes biased and unfair
false
False. Boiling occurs when a liquid changes to a gas at its surface due to the presence of sufficient heat. Heating below the surface does not lead to boiling; it only increases the temperature of the liquid.
False. Acceleration is a measure of how quickly an object's velocity is changing, which includes changes in speed, direction, or both. So, acceleration can occur even if the speed of an object remains constant but its direction changes.

False. Igneous rocks can form both beneath the Earth's surface, where they are called intrusive or plutonic rocks, and on the surface from volcanic activity, known as extrusive or volcanic rocks. Intrusive rocks crystallize slowly from magma deep within the Earth, while extrusive rocks solidify quickly from lava that erupts onto the surface.
