What is one thing that tells a geologist that rock layers have been disurbed?
If rock layers are not horizontal, then some force must have diturbed them after they were fomed.
Scientists believe that the iridium found in some rock layers may originally have come from a?
Meteorite. An asteroid is probably a better description of the thing that hit Earth.
Where are garnet schist rocks commonly found?
Garnet schist-- as well as mica schist--can be found anywhere where clay rock with some calcite content-- such as siltstone or a mudstone, for example-- can be compressed (via metamorphism) and consequently sqeezed into rock-like layers.
What are some of ways geologists study rocks in the field?
some of the ways geologists study rocks in the field are they look for ''outcrop areas'', or ''outcrops'', which are outside places where much rock, mineral, crystal or gem is exposed.
What are wavy features found on some sandstone?
Those are deposition layers influenced by wind or moving water.
What are some places that fossils are most likely to be found?
Rivers,rock outcrops,and slate.
Why can't animals survive on rock platforms?
Firstly, it is hard for animals to have access to sufficient food sources on rock platforms. Also, being in an exposed position makes them more vulnerable to predators such as eagles and hawks. there is no shelter on rock platforms. Some animals do prefer rocky outcrops (such as the rock wallabies of Australia), but these are outcrops and hillsides, not single platforms.
What happens to rock layers along a fault?
Usually along a fault the rock layers are broken and displaced in some manner so that the rock layers are not continuous across the fault.
Does metamorphic rock have layers?
Not exactly. Some metamorphic rocks have foliation, which can appear similar to the layers of sedimentary rock. Foliation develops from mineral grains being oriented by pressure, rather than the deposition of layers.
What are the wavy features found on some sandstones?
The wavy features found on some sandstones are the build up of the different layers of rock the rock has produced over the decades.
What is a Lacolith?
When magma flows between rock layers and spreads upward, it sometimes pushes the overlying rock layers into a dome. The base of the intrusion is parallel to the rock layer beneath it.

How many layers are there in the earth's crust?
The crust alone contains millions of different layers of sedimentary rock. For the layers of the Earth, some of which are rock and some of which are not, see the related link below.

How the relative age of a fossil is determined by studying layers of rock?
It is determined because in layers of rocks the fossils are found so the layers of rocks give information to the scientist about the age of a fossil so like that the relative age of a fossil is determined.
