Imagine that the Earth's plates have stopped moving. Predict what Earth's surface will look like a few million years in the future.
There will be no new mountain ranges, and eventually, everything will become flat because of weathering and erosion.
How do you think the volcanoes in the Ring of Fire formed?
The plates moving towards each other result in the edges of one plate being pushed down into the mantle, which causes the plate above it to melt. Magma rises through vents all around the edges of the Pacific Plate, forming volcanoes.
Palm trees are usually found in warm climates. However, scientists have found fossils of palm trees in Wyoming. What can scientist infer from this fossil record?
Scientist might infer that Wyoming's climate must have been much warmer long ago.
