If a volcano erupts many times over a period of years which of the following landforms is most likely a result of volcano eruptions a valley, a mountain or a canyon explain

If a volcano were to erupt many times, the hot lava quickly cools forming layers of igneous rock which ultimately form mountains due to repeated added pressure of rocks.

Hope this helps!! :D

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
