Which property best describes a rock which has formed from sediments?
The property that best describes a rock which has formed from sediments is that it is usually graded. It has fossils which are in form of rounded particles.
Where do many of these sediments end up?
sediments are carried by different means of travel and are usually end up in basins
Why are the rocks and stones found on pebble beaches usually rounded and smooth?
Because the tides act as a rock tumbler, it slowly smooths them out.More Information:Rocks found on beaches can be smooth for various reasons. The most common is that the washing motion of the waves erodes the sharp corners off over time by knocking little bits of sand and clay into them.Rocks along beaches can also be smooth if they happened to be deposited by glaciers. Rocks brought to a location because of the moving of glaciers long ago are rounded by tumbling around in front of the glaciers.
Why do sediments have angular or rounded fragments?
Angular sediments are usually young or "immature" sediments which have only recently been weathered from a source rock. They have not been exposed to corrosive fources long enough to become worn down. These sort of sediments are common in glacial areas or areas high in a river catchment near their original location.Rounded grains suggest extended periods of transport and mechanical weathering, which chip away the sharper edges of the immature sediments leaving them worn dow. a common example of this is a desert sand, which has been exposed to errosive forces for a long time, being blown around the desert, giving them a rounded appearance.Think of a broken piece of glass. In its "immature form, it has sharp edges and smooth faces. If you throw it in the ocean on a beach, and give it time, the surf and sand will weather it smooth, leaving you with nice smoth beach glass, a mature sediment.
Transported sediments are usually deposited at what location?
a decrease in the speed of the agent of erosion occurs

The property that best describes a rock which has formed from sediments is that it is usually graded. It has fossils which are in form of rounded particles.
Where does the final deposition of sediment usually ocur?
The final deposition of sediments usually occur in their final resting place called the deposition environment. These sediments are buried by other sediments.
Where do many of these sediments end up?
sediments are carried by different means of travel and are usually end up in basins
What sediments make up limestone?
It is usually quartz
Why are sediments usually found in layers?
because they are sedimentary rock
Are there beaches located in Sao paolo?
No. If there are, they are not very known. The best beaches in Brazil are usually in Copacobana and Rio.

What presses sediments together?
Usually weight from above, whether from a body of water or from additional sediments.
If a rock has ripples pointing down what does that mean?
If a rock has ripples pointing downward, it suggests that the rock was formed in a depositional environment where sediments settled or were deposited horizontally or at a slight angle downward. This can occur in environments like riverbeds, deltas, or beaches where sediments are being deposited and compacted over time.
Where does the dirt that covers or forms over the fossils in the strata of the earth come from?
The sediments are usually carried by water or are particles that settle out of water, but the sediments could be windblown.
Where can you usually find rocky beaches?
most rocky beaches are usually found in California (Sandiego area) sometimes not very comfortable for the feet depends how far long the beach is in the breaking down process of a rocky beach turning into a sandy beach, The tide is a another difference of Sandy and Rocky Beaches, rocky beaches usually have a higher tide than a sandy beach does.
