Why would you expect the crystals in an intrusive rock to be larger than the crystals in an
extrusive rock?
a. the crystals in intrusive and extrusive
rocks are generally the same size.
b. intrusive rocks cool more rapidly, which
produces larger crystals.
c. intrusive rocks cool more slowly, which
produces larger crystals.
d. the chemical composition of intrusive
rocks produces large crystals.

C. Intrusive rocks cool more slowly, which produces larger crystals

Explanation:

Intrusive rocks are igneous rocks that form beneath the surface. Unlike extrusive rocks (rocks that form above the surface), intrusive rocks cool down more slowly, so this allows crystals more time to grow before they completely cool down and solidify.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
