Where are most river sediments deposited?
Most of it is trapped at the dam at Lake Nasser. After that it would be deposited when the flow of the river is too slow to carry it and ultimately what is left is deposited in the delta.
What has to happen before a rock layer can be deposited?
The Rock Layer has to harden first of all before it can be deposited.
The top of a sedimentary layer was deposited before the bottom?
Incorrect. The bottom of a sedimentary layer was deposited before the top. Imagine pouring different colors of sand in a clear vial one layer at a time and alternating colors. The color (or layer) on the bottom of the vial was deposited by you very first and the layer on top was last to be deposited.
What does the discovery of a fossil of an ancient fish atop a mountain indicate about Earth's past?
It indicates that the sediments that contained the fossil were deposited in a low area such as a lake, sea or ocean and that the rock formed from that sediment was later uplifted by plate tectonics as part of a mountain range.
Which step in the rock cycle occurs before sediments are laid down?
The step right before is when erosion breaks down rock.
Most river sediments are deposited?
They are deposited at the river mouth, before it finally empties its water into the ocean.
What must sediments that are eroded and deposited go through before becoming a sedimentary rock?
cementation

What is the difference between old alluvium and new alluvium?
Alluvium refers to clay, silt, sand, gravel, or similar detrital material deposited by running water. New alluvium are these sediments that are being deposited right now and older alluvium refers to sediments that were deposited a short while before the new alluvium. For example, a 500 years ago some sediments were deposited in a stream bed and last year more sediments were deposited in that same stream bed. The 500 year old sediment would be older alluvium and the 1 year old sediment would be the younger alluvium.
Where does the slowly running river drop there sediments?
Heavier sediments are more easily pulled down by gravity in slower waters. But they also have the chance to clump together with other sediments and become heavy enough to be pulled down. In faster waters, it pulls the grains and material apart before it can settle and has a stronger force than the pull of gravity.
Farmers on the Nile did not necessarily benefit from the Aswan High Dam Because Of?
Before the building of the Aswan High Dam the river Nile flooded yearly and deposited nutrient rich sediments on the surrounding farmland.
What has to happen before a rock layer can be deposited?
The Rock Layer has to harden first of all before it can be deposited.
Can a post-dated check be deposited before the post date?
yes it can be deposited since checks can be posted before their maturity date
What is when material is carried before being deposited?
bearem
What can form fossils before sediments harden into rock?
Coral reef.

What word is when materials are carried before being deposited?
