The answer is B It must be testable.
False, hearing is caused by the eardrum picking up sound frequencies made by Jil. So its not the air molecules, its the sound waves.
What are the two primary sources of energy for the earth
Trenches are geological feature is most common at oceanic-continental convergent boundaries.
Explanation:
Usually, the oceanic plate, because it is denser, becomes subducted underneath the continental plate. The enormous stress of the two colliding plates causes the plates to warp abit downwards along the boundary causing a trench to form that stretches the boundary.
As the oceanic plate gets subducted and ‘dives’ into the mantle, it begins to melt into magma. Usually, due to the enormous stress along the boundary, fissures develop on teh continental plate along teh boundary. The magma rises through these fissures and erupts at the surface. Several mountains form long the boundary forming another signature geological feature of convergent boundary which is volcanic arc mountains.
