The correct answer is the crust.
The crust is present above the mantle and is the hard outer shell of the Earth. The crust is 0 to 32 km in thickness. The densest type of crust is oceanic crust with the density of 3.0 g/cm3. The mantle is the layer below the crust and above the core.
The mantle exhibits an average density of 4.5 g/cm3. The density increases with depth as the pressure increases. The outer core exhibits a density between the range of 10 g/cm3 to 12.3 g per cm3 and the density of the inner core is about 12 g/cm3. Showing that the inner core exhibits the highest pressure.
Answer:Several theories have been proposed for the formation of desert pavements. A common theory suggests they form through the gradual removal of sand, dust and other fine-grained material by the wind and intermittent rain, leaving the larger fragments behind.
Explanation: scientists have had sever theories as stated in my answer above
Answer:
correct sequence:
make an observation
ask questions
construct a hypothesis
test the hypothesis
analyze the results and make conclusions
communicate the results
Explanation:
Scientific method is a set of steps made in order to perform a proper and valid scientific investigation.
Everything starts with an observation, finding something unusual or interesting that we want to test. After choosing our field of interest, we continue to ask a question; why is something the way it is and what is the reason for that?
Every question needs an answer so we propose a possible answer or a hypothesis. Of course, this doesn't have to be correct or final explanation, but it will be the answer which will we put to the test.
After constructing a hypothesis, we need to test it through researching or experimenting in which we will obtain some date.
Results of our experiment in the form of data must be analyzed and used to confirm or denied.
These results, whatever they may be, will help us to make a conclusion which we'll finally communicate, showing it to the other researchers.
Answer:
DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are. Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Explanation:
Answer:
hydrogen
Explanation:
the more hydrogen ions then lower the ph and the fewer hydrogen lions the higher the ph.
