Earth's Pizza Crust

Cheese is the oceanic crust 

sauce is the asthenosphere 

Meat- lithosphere 

crust - the Earth 

mushrooms = continents

Plate Tectonics

Transform fault - plates slide past one another with no creation or destruction of lithosphere.


Divergent boundary - two plates diverge, or move apart and new crust or lithosphere is formed. 

Convergent boundary  - plates converge, or come together. If a plate of oceanic lithosphere collides with thicker and less dense continental lithosphere, the denser oceanic plate will dive beneath the continent in a subduction zon. 

Project Wet and $100

The Project Wet Foundation envisions a world in which action-oriented education enables every child to understand and value water, ensuring a sustainable future. The mission is to reach children, parents, teachers and community members of the world with water education that promotes awareness of water and empowers community action to solve complex water issues. We achieve our mission. WET provides educational resources, training workshops, and events for educators.


If water was worth 100 dollars:
Oceans - $96.50    had $96
Glaciers/ Ice caps- $1.74  has $2
ground water- $1.69    had $1.60
permafrost - $0.022
fresh water lakes - $0.007
salt water lakes ans seas - $0.006
soil mister $0.001
Atmosphere - $0.001    had $0.40

Rocks Rock!

We are using three different types of candy: Cocoa Krispies, a Butterfinger, and a piece of Peanut Brittle.

Cocoa Krispies -  is an example of an igneous rock


Butterfinger - is an example of metamorphic rock.

Peanut Brittle - is an example of a sedimentary rock.

Salt Crystal Garden

Today in MSED we started the process of making a crystal garden. The supplies we needed were: a plate, 3 sponges, a piece of charcoal, 2 pipe cleaners, 2 tablespoons of water, 2 tablespoons of salt, and 2 tablespoons of Mrs. Stewart's Bluing solution. 

After you need to smash the charcoal into small pieces. Arrange the sponges and charcoal on the plate. Next you need to intertwine the pipe cleaners into the pile.

Next mix the 2 tablespoons of water, 2 tablespoons of salt, and 2 tablespoons of Mrs. Stewart's Bluing solution in a beaker. After the solution is properly mixed, pour it onto the pile (of sponges, charcoal, and pipe cleaners). Lastly, place the plate in the window and let settle.

Marquette Field Trip

Today, MSED 252 took a flied trip around Marquette. Our last spot was at Black Rocks. Black Rocks' are about 3 billion years old. Making it the oldest rock formation in the area. The picture to the left was taken at Black Rocks, on a personal trip. While at Presque Isle, where we saw Jacobsville Sandstone. It is a peridotite composed of serpentine. It has the mottled brown iron characteristic and was deposited in an arid climate.


 The first stop we made on the trip, was to the rock cliffs right across from the Welcome Center. The rocks here were part of the Chocolay  group, ehich is the lowest of the three groups in the Paleoproterozoic-aged Marquette Range Supergroup. Isotopic dating puts these rocks between 2.2 and 3 billion years old. These rocks have characteristics that indicate that they were once part of the ocean. Other features visible are dessication structures, ripple marks, and rip-up beds probably produced by tidal waves.
The middle two pictures are of this rock formation. The third picture was taken in the middle of the hike up the rock.


 The middle stop of the trip was at Tourist Park. The rocks at Tourist Park were interesting because you were able to see where glaciers had cut into the rock. There were also two types of rock present and we were able to determine the lighter rock was around before the darker rock. That is because the lighter rock kept poking through the dark rock.
