Structure Of Ocean Floor Various Landforms

This study is extensive and it has been established that the ocean floor has similar features of mountains and valleys as on the earth.

Structure of ocean floor various landforms. We tend to picture the ocean floor as being as flat and sandy as the beaches with which we are familiar. Most of the oceans have a common structure created by common physical phenomena mainly from tectonic movement and sediment from various sources. This video examines the different types of features in the ocean primarily on the ocean floor. The under water topography maps have been developed by the study of ocean floor topography.

Various features which are generally smaller parts of second order landforms or which form on the second order landforms are known as landforms of third order. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. Trench systems occur for both continent ocean and ocean ocean boundaries the worlds deepest parts of the ocean are found along trenches. In certain portion of the deep sea floor there lies very deep trench or canyons.

This is not the deepest part of the ocean though. Presentation of geologic landform features of the ocean floor as aligned to south carolina state standards. The mariana trench is 11 km deep. Different major landforms on earth major types of landforms on earth include mountains valleys plateaus glaciers hills loess plains and desserts.

Reline features such as bays peninsulas and seas including submerged features such as mid ocean ridges volcanoes and the great ocean basins. The structure of the oceans starting with the continents begins usually with a continental shelf continues to the continental slope which is a steep descent into the ocean until reaching the. Continental slope the steep slope where the contintental shelf drops to the bottom of the ocean floor. Deep depression in the ocean floor called a trench.

When we speak of the topography of the ocean floor we mean the various shapes that the bottom of the ocean can take. The study of landforms is the science of topography. Landform of third order. Mid ocean ridge on the bottom of the ocean there is a central ridge or mountain range that divides the ocean floor into two.

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Trenches are generally 5500 10000 metres deep. This is where the water in the ocean starts to get really deep. 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.
