Ocean Floor Features Model

Mid ocean ridge group of underwater mountain chains criss crossing the oceans.

Ocean floor features model.

Creating a model. Features rising up from the ocean floor include seamounts volcanic islands and the mid oceanic ridges and rises. It is used as a reference to define coastal features and calculate the elevation of topographical elements. Together they contain the overwhelming majority of all water on the planet and have an average depth of almost 4 km about 2 5 miles.

Below the ocean floor there are a few small deeper areas called ocean trenches. Dec 4 2015 explore r naah s board ocean floor followed by 336 people on pinterest. In this ocean characteristics lesson 5th graders complete a kwl chart about the ocean floor use the ocean depth data sheet to create a graph and create a 3 d model of the ocean floor. What are three.

The ocean floor is called the abyssal plain. Most of these features remained unknown to bathymetrists scientists who study the form of the ocean floor until the advent of sonar and satellites. Spreading rates determine if the ridge is fast intermediate or slow. Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet.

Fifth graders make a model of the ocean floor. Mean water level observed for a given duration day month year. The rate at which new oceanic lithosphere is added to each tectonic plate on either side of a mid ocean ridge is the spreading half rate and is equal to half of the spreading rate. A number of major features of the basins depart.

Stability and change clarification statement. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. See more ideas about ocean projects science projects ocean. Ocean basin any of several vast submarine regions that collectively cover nearly three quarters of earth s surface.

Feb 13 2013 oceans cover over 70 percent of the earth s surface. At the bottom the ocean floor features tall mountains expansive plains and deep trenches. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Spreading rate is the rate at which an ocean basin widens due to seafloor spreading.

Develop a model to illustrate how earth s internal and surface processes operate at different spatial and temporal scales to form continental and ocean floor features.
