Which type of material does biogenous sediment form?
Two types of biogenous sediments are calcareous ooze and siliceous ooze.
Which kind of sedimentary rock is formed by cemented shells of marine organisms?
Limestone
What is an organic sedimentary rock composed of cemented shells?
Coquina is an organic sedimentary rock composed primarily of cemented shells of marine organisms.
Cemented shells of marine organisms form which kind of sedimentary rock?
Bioclastic sedimentary rock--coquina.
How did condensation of water vapour form oceans?
The Formation of OceansThe volcanoes on early Earth pumped more and more water vapour into the atmosphere. This caused the atmosphere to change.As the water vapour increased and the temperature of the Earth and its atmosphere continued to fall. This caused water droplets to form in the atmosphere through a process called condensation.As the water droplets increased in size, they eventually fell to the surface of the Earth and accumulated. This was the beginning of the first oceans.The carbon dioxide gas reacted with the accumulated water (dissolution) and the amount of carbon dioxide in the atmosphere decreased. Eventually, living organisms appeared in the oceans. The organisms that evolved used the carbon dioxide available in the oceans in different ways. Some of the marine organisms incorporated the carbon dioxide into their shells. When those organisms died their shells accumulated on the floor of the oceans and became carbonate rocks.Other marine organisms began to use carbon dioxide in chemical reactions to produce sugars that they could store for energy and release oxygen into the atmosphere. This process is called photosynthesis. These organisms were the first primitive plants.Thanks!
Can shells become limestone?
They can, and do. Chalk and coquina are examples of limestone formed from skeletal or shell remains of marine organisms.
What are shells of marine organisms composed of?
The bulk of marine skeletal remains are composed of the mineral calcite. Some marine organisms also have shells of aragonite or silica.
Which of these rocks formed in a marine environment?
Limestone is made by the accumulation of shells and marine organisms.
Which type of material does biogenous sediment form?
Two types of biogenous sediments are calcareous ooze and siliceous ooze.
Which kind of sedimentary rock is formed by cemented shells of marine organisms?
Limestone
What is an organic sedimentary rock composed of cemented shells?
Coquina is an organic sedimentary rock composed primarily of cemented shells of marine organisms.
Cemented shells of marine organisms form which kind of sedimentary rock?
Bioclastic sedimentary rock--coquina.
In dead organisms what change would you expect over time?
Dead organisms (unless specially preserved) will decay, and the soft tissue will rot and eventually disappear, leaving behind only bones or shells (for those organisms that have bones or shells).
Is the ocean floor a good place for fossils to form?
A lot of shells of marine organisms wind up on the ocean floor. Bones do not last on the ocean floor, they get eaten. But shells can last.
Is limestone made up of fragments of granitic and andesitic rocks?
No. Limestone is formed from precipitated calcite or from the shells or skeletal remains of marine organisms.
Many caves in the eastern US were formed with what kind of sedimentary rock that contained remains of ancient marine life?
I believe it is Bioclastic sedimentary rock--coquina although it was formed by shells of marine organisms.
What is one example of evidence from darwins travels that supports an ancient earth?
He found fossil shells of marine organisms high up in the Andes mountains.
