Age Of Ocean Floor Kmz

Molten rock pushes up from the asthenosphere and pushes the plates apart at the mid ocean ridge.

Age of ocean floor kmz.

For that geologists date and study continental crust. This is a mid ocean ridge. Because of this correlation between age and subduction potential very little ocean floor is older than 125 million years and almost none of it is older than 200 million years. This creates new ocean crust.

Ages for ocean floor between the oldest identified magnetic anomalies and continental crust are interpolated by geological estimates of the ages of passive continental margin segments. What major seafloor feature is located at this. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Open the ageofoceanfloor kmz file in google earth.

The scripps sea floor map has also been used to discover a new microplate in the indian ocean. Sea floor spreading answer key. It is an underwater mountain range that forms when magma pushes up on the crust at a divergent boundary. Does the age of seafloor features change with time.

Seafloor spreading is happening at b. In this investigation we will be exploring the age of the ocean floor through using google earth. The file contains 2 separated overlays contours and rainbow isochrons that can be displayed independently. The google earth data right is clearly higher resolution than that version of the scripps map left.

Age kmz google earth file. This kmz file displays the age of the ocean floor in google earth. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. Aug14 14 last modified.

Seafloor age 10my isochrons google earth kmz file of seafloor age with 10my isochrons. How old is the ocean floor. The age uncertainties for grid cells coinciding with marine magnetic anomaly identifications observed or rotated to their. Earth continental geology by era and sea floor physiography for google earth the earth continental geology by era kmz file 802kb references a set of tiled gif imagery representing earths continental geology colored by geological era and grayshade sea floor imagery compiled by the us geological survey.

Therefore seafloor dating isn t that useful for studying plate motions beyond the cretaceous. It was built to help understand the evolution of the earth s modern oceans across geological time.
