Although sedimentary rocks form in a variety of processes, the first process that would occur in the formation of the most common sedimentary rocks would be that of weathering, which is the breakdown of rocks into smaller pieces through chemical or mechanical means by nature.

What is the process by which layers of sedimentary rock are formed?
Sedimentary rocks are formed through the accumulation, compaction, and cementation of sediment particles over time. First, sediments such as sand, silt, and clay are deposited in layers by water, wind, or ice. Over time, the weight of overlying layers compacts the sediments, squeezing out water and air. Cementation then occurs when minerals precipitate to fill in the gaps between sediment grains, binding them together to form solid rock.
What is water vapor turning directly to ice crystals?
The process of water vapor turning directly into ice crystals is called deposition. This occurs when water vapor in the air changes directly into solid ice without first becoming a liquid. This process is often seen in the formation of frost or snowflakes.
What is the first step to the lithification process?
The first step is compaction
What is the first step in making sedimentary rock?
The first step in making sedimentary rock is the deposition of sediments. This occurs when particles like sand, silt, and clay settle and accumulate in layers, usually in areas such as riverbeds, lakes, or ocean floors. Over time, these sediments are compacted and cemented together to form sedimentary rock.
What are two major processes that form sedimentary rock?
Sedimentary rocks require two processes to be formed. The first is weathering. Weathering is the disintegration/decomposition of rocks. Erosion is the process by which the weathered material is moved from one place to another. Erosion occurs when, for instance, a moving stream picks up a weathered pebble and moves it miles downstream to the mouth of a river. Erosion can also take place with ice, wind, etc.
Does weathering go with metamorphic or igneas or sedimentary?
Weathering can happen to any rock. It is the first stage in the process that leads to the formation of sedimentary rock.
What is the steps of the formation of the sedimentary rock?
The first step is weathering.
what is the first step for formation in. sedimentary rocks?
Weathering
What occurs first labor cleavage implantation gastrulation or formation of placenta?
cleavage->gastrulation->implantation->formation of placenta->first labor
What disease occurs when the rate of bone resorption exceeds the rate of bone formation?
Osteopenia (little bone) will occur first. If the process continues, then osteoporosis (thin bone) will occur.
Which process is the first step in the formation of urine in the nephrons?
filtration
Which process occurs first in the cell cycle: mitosis or meiosis?
Mitosis occurs first in the cell cycle before meiosis.
What is the formation of sedimentary rock?
the formation of a sedimentary rock is first weathering. Weathering breaks into smaller piece's. Next is erosion. Erosion is when it moves the sediment to different places. Deposition after that and what deposition do is forming a sedimentary rock when it rains, snow ect. It slows the rock formation down and less energy and sediment will be on the sedimentary rock. Last it is compaction. and that squeezs the sedimentary rock together
Define cementation and compaction?
Sediments are in sedimentary rocks. Everyday, more and more sediment is layed on top of the first batch of sediment(first layer). As the layers build up, they begin to press down on that first layer of sediment, pushing most of the air and water out of it, pushing the particles closer together. This is the process of compaction. This process occurs underground or above and is part of the way that sedimentary rocks are formed.Cementation is the next step in the recipe for making sedimentary rocks. In this step, loose sediments are glued together naturally glues like calcite and silica.
What comes first gastrula or blastula?
The blastula is the developmental stage that forms before the gastrula. During embryonic development, the blastula undergoes a process called gastrulation, which results in the formation of the gastrula.

Which typically occurs first in birthing process?
The baby is pushed out of the uterus
