Bedding planes in sedimentary rocks indicate what?
They indicate a depositional event.
What are facies changes in sedimentary rocks?
a rock specimen of a particular depositional enviroment
What is the depositional environment of conglomerate rock?
Conglomerate rocks can sometimes have spaces between the rocks and other times be filled in with a matrix cement, like concrete. A common place to find conglomerate is near a river. Rivers, because they move at different velocities, are able to transport and deposit rocks of all different sizes.
What feature of sedimentary rocks forms inclined grains as layers move forward?
Cross-bedding refers to inclined layers in sedimentary rock that were formed as a result of wind or water driven ripples or dunes in the original depositional environment.
Do sedimentary rocks have bands of minerals?
Yes, sedimentary rocks can contain bands or layers of minerals. These bands are often formed through various processes such as sediment deposition, compaction, and cementation. The minerals within these bands can vary in composition and can provide valuable information about the depositional environment and the history of the rock.
What is meant by a 'high energy' depositional environment?
a high energy depositional environment is one in which enough energy was present to transport large materials such as rocks and boulders. a low energy depositional environment like a stream is only able to transport materials such as fine sands.
What is the sliding rocks of racetrack playa?
A Sliding Rocks of Racet
Bedding planes in sedimentary rocks indicate what?
They indicate a depositional event.
Why do some rocks have different minerals?
the reason is because rocks can have different depositional environments and diagenesis history.
What is a Sedimentary depositional environment?
An sedimentary enviorment is when all the rain rains in a puddle and all the rocks settle and a sedimentary enviorment develops/forms. This is my thinking/opinion.
What are facies changes in sedimentary rocks?
a rock specimen of a particular depositional enviroment
In which environment might you expect a deposit of rocks Salt or rock gypsum to have formed?
shallow sea

Were can the sliding rocks of racetrack playa be found?
They can be found in Death Valley National Park.
What is the difference between depositional contact and fault contact?
depositional contacts occur between rocks that formed when sediments were deposited on other sediments.fault contacts are usually shown as thick black lines on geologic maps
How was the Racetrack Playa formed?
rocks big and small glide across a mirror flat landscape.
