What characteristic of the depositional environment influence

Geography
1 answer:
madam [21]3 years ago
7 0

Answer:

The characteristic of the depositional environment affects the properties of sedimentary rocks are as follows-

(1) <u>Lithology-</u> It describes the constituent mineral and the type of texture these crystals have, which forms a sedimentary rock. These minerals occur in a certain depositional environment. When the weathered materials are derived and transported to some other place, then it forms a stable one in a fixed environment as the rocks are subjected to compaction and lithification, The environment in which these minerals have led to the formation of these rocks can be determined.

(2) <u>Structure-</u> There are various structures that occur in rock, such as ripple marks, cross-bedding that highlights the flow direction of water and wind. Many structures like slickensides, folding, faulting occurs in the sedimentary rocks that are formed due to tectonic activities. These structures can easily be identified and their environment of deposition can also be determined.

(3) <u>Fossil content-</u> Fossils are found to be embedded in the sedimentary rocks. The shells of organisms after death are accumulated at the bottom of the ocean. As a result of this, these shells are covered with the sediments and after millions of years, turn into fossils. For example, Sandstone, Limestone, and shale comprised of various types of shells. These fossils are found to be deposited in a shallow marine environment.

Why are Earth's continental plates continually in motion?
Ainat [17]

Answer:

C: Plates float on the liquid mantle located below the crust.

Explanation:

Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.

Scientists once thought that Earth’s plates just surfed on top of the mantle’s giant convection cells, but now scientists believe that plates help themselves move instead of just surfing along. Just like convection cells, plates have warmer, thinner parts that are more likely to rise, and colder, denser parts that are more likely to sink.

A decision matrix chart is a useful tool for
Wewaii [24]
Step 1

List all of your options as the row labels on the table, and list the factors that you need to consider as the column headings. For example, if you were buying a new laptop, factors to consider might be cost, dimensions, and hard disk size.

Step 2

Next, work your way down the columns of your table, scoring each option for each of the factors in your decision. Score each option from 0 (poor) to 5 (very good). Note that you do not have to have a different score for each option – if none of them are good for a particular factor in your decision, then all options should score 0.

Step 3

The next step is to work out the relative importance of the factors in your decision. Show these as numbers from, say, 0 to 5, where 0 means that the factor is absolutely unimportant in the final decision, and 5 means that it is very important. (It's perfectly acceptable to have factors with the same importance.)

Tip:

These values may be obvious. If they are not, then use a technique such as Paired Comparison Analysis  to estimate them.

Step 4

Now multiply each of your scores from step 2 by the values for relative importance of the factor that you calculated in step 3. This will give you weighted scores for each option/factor combination.

Step 5

Finally, add up these weighted scores for each of your options. The option that scores the highest wins!
