What do you know about a rock layer found on a mountain if you find a seashell fossil?
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.
Why do rock and not fossils form sedimentary rock and not igneous rock?
Because sedimentery rock is formed under the sea, sediment collects at the bottom of the ocean, and so does a few dead sea creatures, then t gets squashed by other sediment, igneous rock is formed by lava cooling, so there is no fossils in it.
How are shingle beaches formed?
the way a shinge beach is formedthe first thing that happens when a shingle beach is formed is rocks fall from a cliff and end up into the sea. The sea then erodes(rubs) against the rock and it makes the rock smaller . The rock is then moved from the sea to the shore(s).
When waves cut large holes into the fractured or weak rock along the base of a sea cliff. what is formed?
Sea caves.
What type of sedimentary rock formed from the remains of coral and sea shells?
Limestone and chalk.

What are two results of waves along a coast?
Two results are:A sea arch,when waves erode a layer of softer rock that underlies a layer a hard rock.Another one is a sea cave,which is formed when ocean waves hit against a steep and rocky coast lots of times.

In which environment might you expect a deposit of rock salt or rock gypsum to have formed?
shallow sea
What type of rock is formed by weathering and layering?
A rather simplified answer: Weathered rocks are broken down by ice, rain and wind, into smaller rocks, pebbles, sand, and silt. When the lighter sand and silt is carried by rivers, etc. and reaches the sea, it may form a layer on the sea bed. If the layer is placed under tremendous pressure, and is mainly of sand, sandstone is formed (over many eons). If mainly silt, slate is formed.
What rock is formed from the shells of sea creatures?
A sedimentary rock called coquina.

What sedimentary rock formed from the shells of sea creatures?
The rock would be limestone, the mineral would be calcite.
