13) Patch Conditions the sample was subjected to
Results
Patch 1 Watered occasionally, soil was sandy Seeds did not germinate
Patch 2 Watered regularly, soil had lumps of clay A majority of seeds germinated
Juan and Melissa were planning to grow some plants for a science experiment. They started with seeds, 100 seeds each. Juan
planted his seeds in sandy soil. Melissa planted her seeds in soil that had more clay and less sand. They tracked the seed sproutin
also called germination, in both plots. Juan concluded that seeds germinated best in clay soil, not sandy soil.
What is another explanation of their results, based on their recorded data?

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
