Answer:
The answer choices to this question are:
A) She releases cement particles into a random number of the coral samples.
B) She uses three different types of coral to establish her dependent variables.
C) She treats the coral samples identically with varying levels of carbonic acid.
D) She obtains her coral samples from coral reefs surrounding different continents.
Best Answer is:
A) She releases cement particles into a random number of the coral samples.
Theory:
It has been researched that ocean acidification caused by carbon dioxide emissions causes a decrement in the coral reef growth and this will keep slowing down unless steep and rapid reductions in greenhouse gas emissions are made. And the Coral reefs offered economic opportunities would advantage the surrounding communities from fishing and tourism.
i did this question so thats why i know the answer choices
hope this helpsss
Answer:
D. hotter rock rises and cooler rock sinks.
Explanation:
We know that as we move <u>towards Earth's center</u>, the <u>temperature rises</u>. This rise in temperature causes rocks to melt (magma). The high temperature and melting of rocks <u>decrease the density of material </u>which makes it <u>move upward</u>. By <u>moving upward</u>, the molten rock <u>starts turning solid</u> and becomes <u>denser again</u>. Here, it <u>sinks back due to gravity</u>. This upward and downward movement of rocks due to density and temperature makes a convection cell.
PS: The formation of convection cells in Earth's interior is also the reason for plate tectonics.
