Design Decisions: False Alarms My proposed design had (insert #) false alarms. My goal was to have 0 or 1
false alarms; therefore, that goal. However, I knew false
alarms might be acceptable over 50 years. Based on my research, I knew that
(type of) sensors give alarms for any earthavake over
7.0, but the data from this type of sensor was less reliable, so we only used
(insert #). We also learned that type of) sensors give false
alarms for local tsunamis, but we found that they broke easily. Therefore, I kept
the false alarms low by placing some shallow sensors further away from local . We also used (insert #) deep sensor(s). Since the deep sensor(s)
was/were far enough from local
or other plate
it/they
was/were not involved in any false alarm cases?

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.
