Describe how plates create mountains.
Two plates move toward each other and when they come touch, they push against each other. Because of the force, the edges of the plates then get pushed upwards, creating mountains.
Explain how fossils from ocean organisms might appear at the top of a mountain.
The organisms lived and died in the ocean. Their bodies or shells fell to the ocean floor and became fossils in sedimentary rock. Then, the ocean floor was pushed up when two plates came together and made a mountain. When the floor was pushed up, it carried the fossils with it.
