Continental Drift‚ Plate Tectonics‚ The North American Plate The experts and scientists have theories on how the the world’s plates move and how earthquakes occur. These theories on how the world’s plate move is called continental drift and the theory on how earthquakes occur is called plate tectonics. They also have a lot of information on the North American Plate and in which direction it is moving and information like that. Now let me tell you more about each of these topics. Continental

that will be of use to you throughout your biological work. Procedure 1. Heat the test tubes of sterile agar medium in the water bath until the agar melts. 2. Remove the test tubes from the water bath. Let them cool enough to hold in your hand‚ but not so much that the agar becomes solid again. Perform the following transfer as quickly as possible. You must work rapidly so that the liquid agar will not cool and solidify before the transfer is completed. 3. Hold both a test tube

on bacterial growth. By observing the effects of 5 different inhibitors including alcohol‚ bleach‚ soap solution and distilled water‚ it was determined what antiseptic or disinfectant was able to best inhibit this kind of bacterial growth. Nutrient Agar was poured into a Petri dish with four quadrants and then a pipette was used to place bacterial culture on top. Using forceps‚ a filter disc was dipped into each inhibitor and then into a separate quadrant of the Petri dish. The lid of the Petri dish

The Movement of Plate Tectonics Brandon Womac Plate tectonics have played a major role in the history of the Earth. All seven continents are where they are today due to the movement of plate tectonics. These seven continents were one big supercontinent called “Pangea” about 200 million years ago before breaking apart. The three different types of plate boundaries are convergent‚ divergent‚ and transform. These plate boundaries form due to the earth’s outer shell called the lithosphere having multiple

Clare Worley 6S 4 - 16 - 18 What Surface in OLV has the most Germs? Introduction I have tested several surfaces in Our Lady of Victory to see which surface has the most germs. I tested ten surfaces and let the petri dishes grow for five days. Over the five days I counted the spores each day and took pictures every other day. It is amazing how things can look and feel clean but they are actually filthy. It is also crazy how many surfaces we touch every day and how one

water because without anything to help it‚ water cannot do anything. For example‚ if you wash your hands and you do not use any soap‚ none of the germs on your hand will be cleaned. Materials: The materials we used in this lab were a petri dish with agar‚ forceps‚ water‚ alcohol‚ hydrogen peroxide‚ antibacterial soap‚ filter paper disc‚ tape‚ and a permanent marker. Procedure: We started this lab on May 12‚ 2014. Using a permanent marker on the bottom of the dish‚ we divided it into 4 sections.

How does the plate tectonics theory help explain the existence of fossilized marine life in rocks atop the Ural Mountains? Be sure to include a description of the specific process(es).’ Continental Collisions would be a possibility as this would birth mountain building. It is a theory that Europe and Asia collided millions of years ago. Marine life would have existed in the ocean basin between the land masses. As the continents approached‚ waters would recede from between them through subduction

1. Compare the age of igneous rock found near the mid-ocean ridge with that of igneous rock found farther away from the ridge. The ages of the igneous rock found near the mid-ocean ridge was younger than the igneous rock found farther away from the ridge. This is because of convection currents. Magma rises because it is less dense. It is forced out of the ridge‚ it spreads apart‚ and when it cools‚ it becomes new seafloor. This is why newer seafloor (igneous rock) is younger when it is closer to
