Rock Cycle
What are the three different types of rocks?
Sedimentary, Igneous, Metamorphic
What did we learn about in the convection lab?
In the convection lab we observed that when the hot bottle is on top nothing happens but when the hot bottle is on the bottom it gradually goes back to the top. So the heat always rises to the top.
What are fossils made of?
Fossils are made from bones, shells, teeth, and plant leaves.
How does the first car connect to rock cycle?
The connection between the first car and rock cycle is in the materials and process used to create the car. The first cars were built with iron and steel. These metals are extracted from the Earth's crust. The metals form from geological processes within the rock cycle like cooling of magma, sedimentation, and metamorphism. The first car also ran off of gasoline which comes from crude oil which forms from organic matter buried under layers of sedimentary rock. This matter is heated over tons of years as part of the rock cycle.
How do the three types of rocks form?
A sedimentary rock forms from deposits from old living things or rocks. Igneous rocks form from cooling magma, it cools fast to make small crystals and it cools slowly to make big crystals. And then metamorphic rock forms from existing rocks are put under heat and pressure to form the rocks.
What are the three types of plate Boundires?
Divergent, Convergent, Transform
What are the steps in how fossils are made?
The fossil usually starts by an animal or a living organism dying. Then over time sediment like sand or mud covers up the remains of the organism. This usually builds layers upon the organism creating pressure. Then water gets into those layers or dust or mud, which gets on to the organism replacing the matter with minerals. Then over a long period of time the organism turns into stone creating a fossil.
How do cars from the 2000's connect to plate tectonics?
Cars in the 2000s relate to plate tectonics by the resources used to power them, which are made from tectonic processes. Plate tectonics cause formations of sedimentary processes where oil and gas get formed formed from matter and organic matter. Cars in the 2000's used gas to power them and oil to help the engine. These cars also drove on bridges and highways. Plate tectonics can cause earthquakes which affect road designs that the cars drive on.
What are examples of rocks that are the three types of rocks?
Examples of sedimentary rocks are limestone, sandstone, and shale. Examples of igneous rocks are obsidian and granite. And examples of metamorphic rocks are marble and gneiss.
How does convection relate to plate tectonics?
This applies to tectonic plates because of the magma in the middle of the core. This gets really hot which hits the crust that is cold. This creates currents because the cold and heat circle together. This is a flowing current, the current will then reach up or suck in tectonic plates which pulls them out or together creating mountains, canyons, and faults.
What are three types of relative dating?
Stratigraphy, Principle of Original superposition, Fault, Principle of cross cutting relationships, Principle of superposition, and Principle of faunal succession
How do the new cars connect to Rock ages?
New cars and more evolved cars are electric and use batteries. Electric cars use lithium battery which depend on the minerals like lithium and nickel. These different minerals form over geological time. The minerals get extracted from the earth. This happens when volcanoes erupt and other big erosions. New cars also use glass windows that are made from silica glass. This product also forms from sedimentary processes.
What are the three types of rocks environments?
One environment that sedimentary rocks come from are rivers. The flowing water moves sand and mud down the river. Then when the river slows those clumps get turned into sediment. An environment that igneous rocks come from are volcanoes. The lava erupts and then it hits the rock where it gets cooled on the surface. Metamorphic rocks can be found in large mountain ranges. The pressure and heat are very high in these ranges which squeezes the rocks changing them.
What do the three types of Plate boundaries mean?
Convergent plate boundaries happen when two tectonic plates move toward each other and collide into each other. Divergent plate boundaries occur when two tectonic plates move away from each other. Transform plate boundaries happen when two tectonic plates slide past each other horizontally
How do stratigraphy, Principle of superposition, and fault techniques work?
Stratigraphy, this strategy uses the study of the sequence and conditions of the different layers in a rock. Principle of superposition, this technique is the idea that the oldest layers are on the bottom and the younger layers are on the top. A fault is an event that changes the existing rock.
How do the three type of rocks change?
One way a sedimentary rock changes is weathering. Weathering breaks down the rock into sediment by chemical, biological, and mechanical weathering. A way that an igneous rock breaks down is cooling. The cooling has two ways extrusive and intrusive. And then metamorphic rocks break down by heat and pressure and melting.
How do we know about continental drift?
We know this because Alfred Wegner had a theory of continental drift. His theory was that he had seen coastlines and noticed that they matched up and looked like they used to be together. People didn't believe this theory because he was a meteorologist and not a geologist. He had also found animal fossils that had lined up along the continents.
What is one type of absolute dating, and how does it work?
Radioactivity. Radioactivity can tell time by measuring how much of the element carbon -14 was in the living organism. This element decays at a steady rate as its elements start to die. Scientists are able to work out how much carbon -14 was left in the dead organism and get a good idea on its age. Carbon -14 decays over 5,600 years and that's known as its half life. So scientists can see what the organisms half life is at and see what the age of the organism is.
