Plate Tectonics Lab Examining The Ocean Floor Answers

What lies directly beneath the crust.

Plate tectonics lab examining the ocean floor answers.

Paleomagnetism and the ocean floor lab answers sea floor spreading homework modelling the ocean. As upwelling of magma continues the plates continue to diverge a process known as seafloor spreading. When the magma pushes up to the surface and cools it creates new land. Solved lab 2 plate tectonics and ocean geography oce 30.

Of sea floor spreading and plate tectonics the regions that hold the unique record of earths magnetic field lie along the mid ocean ridges where the sea floor is spreading start studying sea floor spreading. Later studies of the oceans provided one of the keys to the plate tectonic theory. Sea floor spreading project answer key lab 4 sea floor spreading lab sea floor spreading project answer key lab 4 seafloor spreading. You will also expand your skills in map reading and interpretation building on what you did in the maps charts lab.

Plate tectonics and earth s interior the age of the crust 10. The slowest spreading rate. Whats people lookup in this blog. Name class date chapter 9 plate tectonics exploration lab paleomagnetism and the ocean floor when wegener proposed his hypothesis of continental drift little was known about the ocean floor.

Plate tectonics sea floor geography lab in this lab you will explore how the movements of the earth s tectonic plates relate to earthquakes volcanoes and the major geographic features of the ocean floor. These age data also allow the rate of seafloor spreading to be. Go further magnetic polarity record pacific ocean ridge crest ocean floor crust south atlantic ocean fed c b a 39 km 2 million years north atlantic ocean 0 20 40 km scale answers to procedure questions 1. This occurs very slowly and creates about 3.

Plate tectonics plate tectonics seafloor spreading. He thought that the continents plowed through the ocean floor like icebreaking ships plowing through ice. What happened to the ocean crust that made up the ocean seafloor 4 000 million 4 billion years ago 9 lab 1. Samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading centre important evidence in favour of this process.

Two students are discussing why rocks are older on continents. They are pushed apart by magma or melted rock frombeneaththeearth ssurfac e rising up and cooling. Where is the fastest spreading rate. How many large plates form the outer shell of the earth.

For other divergent plate boundaries on earth. Seafloor spreading at divergent zoneson the ocean floor plates are moving away from each other. Continental crust is much farther from divergent plate boundaries than is oceanic crust. Plate tectonics the theory that the earth s lithosphere consists of large rigid plates that move horizontally in response to the low of the asthenosphere beneath them and that interactions among the plates at their borders cause most major geologic activity including the creation of oceans continents mountains volcanoes and earthquakes.

Please fill in the missing labels. The upper mantle and crust make up what major tectonic feature of our planet.
