Igneous rock


Where do sediments settle in layers?

Sediments settle in layers at the bottom of bodies of water, such as lakes, rivers, and oceans. Over time, as more sediments accumulate, they become compacted and cemented together to form sedimentary rock.


Why are sedimentary rocks formed in layers?

Sedimentation of transported weathered and eroded material is continuous, cyclical, or event based. New sediments are deposited on top of existing sediments, forming layers that may be visible in a sedimentary rock body.

What are Solid particles that form layers at the bottom of ocean or lake?

These are sediment particles, such as sand, silt, and clay, that settle down due to gravity. Over time, these sediments accumulate to form layers called sedimentary deposits.


What is the process of pressing sediments called?

The process of pressing sediments together to form solid rock is called compaction. It occurs when layers of sediment accumulate on top of each other, with the weight of the overlying layers causing the sediments to be pressed tightly together.


How do sediments lay when they deposit in lakes or oceans?

When sediments deposit in lakes or oceans, they typically settle in layers on the bottom of the body of water. Over time, these layers can build up and form sedimentary rock.


When sediments are disturbed the oldest layers are found at the?

In disturbed sediments without layers, the relative age of the sediments would be unknown.


How were coal deposits formed in western Canada during mesozoic era?

Layers of sediments compressed the layers of vegetation to form the coal deposits.


Evaporation and precipitation of sediments forms what?

Evaporation and precipitation of sediments can form sedimentary rocks over time through the process of lithification. This involves the compaction and cementation of sediments, creating layers of sedimentary rock.


What is it called when the rock layers form parallel to each other?

When rock layers form parallel to each other, it is called stratification. This process occurs when sediments settle and accumulate in horizontal layers over time, resulting in distinct bands or layers of rock.
