What is an object that forms when sediment fills a mold and becomes a rock?
It is a cast fossil.
Which type of fossil forms when an organisms hard parts dissolve and leave a cavity that laters fills with sediment?
Cast
What must form first for a cast to be made?
📷 Organisms buried in sediment slowly decompose, leaving a cavity that contains an exact imprint of the organisms' shape and size. When this hollow space fills with material, this material takes the shape of the mold, forming a cast.
During the rock cycle rocks get broken apart by weathering carried along by erosion and eventually deposited in a body of water What happens next?
It depends on where the sediment is deposited. Not all sediment is deposited in a body of water. If the transport mechanism is a stream then the sediment can be deposited on the flood plain of the river or in a lake. If the sediment is deposited on the flood plain it will do two things. 1) The sediment of the flood plain will eventually lithify and 2) The river will continue to down cut and after X number of years the flood plain will no longer be subject to the flood waters of the river. At this point it is classified as a terrace (a flood plain of the past that is no longer inundated by flood water). The cycle basically starts over at this point with weathering and erosion processes breaking down and transporting the terrace sediment back into the river. If the sediment is transported to a lake, a delta will form. As the sediment is deposited in the lake the main channel of the river will extend out into the lake, this lowers the gradient of the main channel which slows the flow of water through the channel and allows for the deposition of sediment in the channel. When the main channel fills with sediment and no longer has the ability to channel all of the water from the river, dis-tributary channels will form these dis- tributary channels migrate across the delta transporting sediment as they go. Lithification takes place in the lower layers of the delta but this lithified sediment is only subjected to erosion during very high flows that are capable of transporting the sediment that covers the lithified layers.Basically, no matter where the sediment is deposited, it is subject to the processes which weathered and transported it to its current location.Wow really? these guys are just looking for a basic answer not an essay
How is a cast fossil different from a mold fossil?
if the original organism dissolves or decays, leaving a hollow in the rock, that is a mold. If the mold fills up with sediment which gradually hardens into the shape of the original organism, then that is a cast. Casts are copies of fossilized plants or animals. Molds are hollow impressions of the fossil.
When sediment fills a mold and becomes rock a blank is created?
cast
What process happens when sediment fills a mold and becomes rock?
Lithification.
What is an object that forms when sediment fills a mold and becomes a rock?
It is a cast fossil.
Which type of fossil forms when an organisms hard parts dissolve and leave a cavity that laters fills with sediment?
Cast
What is a mold and cast fossil?
A mold and cast fossil is and exact stone replica of an organism but it is formed like this. The first layer of sediment hardens and forms a mold. then a new layer of sediment fills in the mold and hardens. That is the cast.
Which forms first a fossil mold or a fossil cast?
First, a thin layer of sediment hardens and forms a mold. Then, what is known as a cast is when a new layer of sediment fills in the mold breaking down the creature/ animal/fossil.
What is mold and cast fossils?
A mold and cast fossil is and exact stone replica of an organism but it is formed like this. The first layer of sediment hardens and forms a mold. then a new layer of sediment fills in the mold and hardens. That is the cast.
The function of the fluid that fills the pericardial sac is to decrease what?
Friction around the heart and possible damage.
Cavity in rock made when an organism decayed?
A cavity in the ground where organisms can be buried is called a hole. If sediment fills this hole the organism may become fossilized.

The answer varies... It won't be possible to find an answer unless every woman in the world fills in a poll. A lot!!
