Plate Tectonics Project Blog 3/30/18

Summary:              This week in science we completed our Plate Tectonic Projects. What we had to do for this project is choose what our presentation was going to be about (I chose to do mine on earthquakes and fault lines in Northern California) then create a written report and 3 minute ignite presentation on active fault lines in Northern California. What I learned through doing this project is all about active fault lines, and more specifically in Northern California. What I now know about faults in general is what a fault is, what an active fault is, why an active fault is a hazard, how to prepare for an active fault, and more. What I now know about faults in Northern California is the most dangerous faults in Northern California, the history of faults in Northern California, why Northern California has earthquakes and faults, and more.. A fault is a fracture in the earth's crust that is created through a transform boundary where earthqu...

Earthquakes & Fault Lines in Northern California 3/24/18

San Andreas Fault Link Summary:        This week in science I learned about earthquakes and fault lines and more specifically in northern california. What I now know about this topic is what a fault is, what an active fault is, why an active fault is a hazard, certain active faults in northern california, and recommendations for people who are living near active faults. A fault is a fracture in earth's crust created by a transform plate boundary. An active fault is a fault that has moved in the past 120,000 years, though it isn't insanely dangerous. A fault that has moved in the past 5,000 years is also considered an active fault, just a much more dangerous fault. Active faults are a hazard because active faults are what create an earthquake. An earthquake can ruin someone's life, or even do worse such as take a life. An active fault can simply affect your life for the worse with just an instant movement., which is why active faults are so hazardous. There are ...

Plate Tectonics Quiz Corrections 3/12/18

Question 2:  This answer is correct because of the fact that Alfred Wegener did not have enough evidence to convince scientists. This would make much more sense for the reason that the scientists didn't believe him rather than my answer. Question 10: This answer is correct due to the fact that plate tectonics is about the plates of the earth that get moved by convection currents. Question 16: This answer is correct because of the fact that the image is showing two plates spreading apart, which is the exact movement of divergent boundaries. Question 20:  This answer is correct because of the fact that divergent boundaries form oceanic trenches when they spread apart. When the two plates spread apart, it creates a trench on the ocean floor. Question 29: This answer is correct because when two plates create a subduction zone lava can spill through the hole that is created from the subduction zone. This will allow the magma to dry and create...

Plate Tectonics 3/10/18

Summary:        This week in science we learned about Plate Tectonics. Plates have been on Earth for thousands of years and are consistently moving (very slowly). Through this the Earth can recycle our land, by destroying the old land, and creating new land. These plates are made of rock and are in the lithosphere layer of the Earth. Another thing I know is that there are 3 different type of plate boundaries. Those three types of plate boundaries are convergent boundaries, divergent boundaries, and transform boundaries. Convergent boundaries are when two plates collide and their are two different types of convergent boundaries. The two types of convergent boundaries are collisional boundaries and subduction zones. A collisional boundary is when two plates with the same density collide. Because they are the same density the plates buckle and warp. The land then pushes up into jagged peaks forming a mountain. Subduction zones are when one dense ocean plate converges...

The Different Layers of the Earth 3/4/18

Summary: Link        This week in science we learned about the different layers of the Earth. I now know that there are two ways that scientists label the layers of the earth. Those two ways are labeling the Earth's layers by its Compositional Layers and by labeling the Earth's layers by its Physical Layers. What I know about the Compositional layers are that there are three different layers that make up the Compositional Layers. Those three layers are The Crust, The Mantle, and The Inner and Outer Core. What I know about these three different layers are their thickness, what they are made of (composition), and their state of matter. For example, The Mantle is roughly 2900 km thick, it is made up of hot semisolid silicate rocks, iron, nickel, and magnesium, and its state of matter is semisolid. What I know about the Physical Layers of Earth are what the Physical Layers are based off of. The Physical Layers of the Earth are base on how the layer looks or acts. ...
