2. Your project should include descriptions of each as well as two examples.

3.You should present your research in a creative and detailed project. You may choose one of the following formats, or have another format approved by your instructor:

Slide-show presentation
Website
4. Be sure that your project:

is your own work and all text is written in your own words
includes citations of all resources used for your research
is presented in a way that is neat, organized, and clear
complete sentences should be used in all written descriptions and explanations

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.

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.
