Similaire à Here are possible answers to the evaluation questions:1. Which feature forms most of the ocean floor? - The continental shelf forms most of the ocean floor.2. Where would you find the best fishing zone according to the features of the ocean makeup? - The continental shelf would be one of the best fishing zones as it is relatively shallow and productive.3. Where is new ocean floor created? How old is the ocean floor? Explain. - New ocean floor is created at mid-ocean ridges through the process of seafloor spreading. The age of the ocean floor gets older the further you move away from the mid-ocean ridge, with the oldest ocean floors being about 180 million years old located

- 1. How to make an ocean floor model
- 2. EXAMPLE 1 The Ocean Floor - Plan: Find the definitions for continental slope, trench, basin, . continental shelf, and range. These definitions are the required background knowledge. Materials: Draw a quick plan of an ocean floor as seen from the side; including the edge of a continent, a continental shoebox with a lid - 1 per group of shelf, a continental slope, a basin, a trench, and a range. 2-3 They require their definitions to do this. When the plan is checked and they can properly identify paper mach, materials (flour, water, each part, the groups set out to create the ocean floor in their shoebox with paper mach. glue mixed in a bowl) strips of newspaper or newsprint pencil scissors Craft paper
- 3. When the paper mach is dry (or close), the groups cut or punch about 8 holes spaced evenly apart down the centre of the shoebox lid. The lid is then put on the box, hiding the ocean floor. Once the graph is set up properly, The students take their graph the students put the dowel in paper and create a graph with the hole #1 until it hits "bottom". numbers one to eight along the They record the measurement on bottom (number of holes) and the graph with a simple dot. This about 1-25 (measurement in cm) continues for holes #2-8. up the other side. When all of the holes have been measured, the students should join their dots using a ruler in order. When this is done, they should turn their graph upside down and label the parts of the ocean floor appropriately. They should see a representation of the floor they created in the shoebox.
