Asked in Geology, Scientists
How do scientists determine the age of Earth's structures?
The lowest layer of rock or of a structure would be known as the oldest. The highest layer is then known as the newest/youngest. Scientists can't exactly determine the age of a rock but they can determine which layer is oldest and youngest, and then try to determine the age of the ones in the middle off of the basic observation.
Asked in Fossils
Why would you find the oldest fossils at the bottom of a cliff and the youngest fossils at the top of a cliff?

What do you know about a rock layer found on a mountain if you find a seashell fossil in the layer?
If you find a seashell fossil in a rock layer on a mountain, than you know that the rock layer was formed at a time when that area was submerged under water. This is because the seashell lived and died underwater, so it would have been fossilized there as the rock layer formed. Millions of years later, the water drained away, and forces within the Earth's crust pushed the rock layer and the layers above it upward, forming mountains. Of course, the rock layer would have been buried deep within the Earth by that point, but as the mountains formed, weathering and erosion would have worn away the newer layers, exposing the ancient rock layer with the seashell.
