Oceanic Relief Overview

The submerged extension of a continent, sloping gently from the shoreline to a depth of about 200 meters. It's a rich ecosystem for marine life.

A steep incline that marks the transition between the continental shelf and the deep ocean floor. It can have depths ranging from 3,000 to 4,000 meters.

A gently sloped area at the base of the continental slope, formed by sediments deposited over time. It acts as a transition zone between the continental margin and the abyssal plain.

The collective term for the continental shelf, slope, and rise. These underwater features represent the submerged edges of continents.

Large depressions in the ocean floor, often filled with water. They encompass a range of underwater landforms.

Vast, flat regions on the ocean floor, formed by sediment deposits from continents. They are generally devoid of major relief features.

Long, narrow depressions in the ocean floor, where tectonic plates collide and one plate dives beneath the other (subduction).

Areas where new oceanic crust is created as tectonic plates diverge. They form underwater mountain ranges with a ridge running down the center.

Volcanic hills that rise from the ocean floor, often reaching up to 1,000 meters in height.

Regions where the Earth's tectonic plates move apart, allowing magma to rise and form new crust. This process happens at oceanic ridges.

The process where one tectonic plate slides beneath another, often leading to the formation of ocean trenches and volcanic arcs.

Areas where the Earth's tectonic plates collide, resulting in either the formation of mountains or subduction zones.

Areas where the Earth's tectonic plates move apart, causing magma to rise and form new crust. This process creates oceanic ridges and spreading centers.

Areas where the Earth's tectonic plates slide past each other horizontally, leading to earthquakes and transform faults.

The theory that explains the movement of the Earth's tectonic plates and the formation of various geological features.

A type of rock formed from the cooling and solidification of magma or lava.

A type of rock formed by the accumulation and cementation of sediment particles.

A type of rock formed when existing rocks are transformed by heat, pressure, or chemical reactions.

The process by which rocks are broken down into smaller pieces by physical or chemical weathering.

The process by which rocks are broken down into smaller pieces by physical or chemical means.

The process by which sediment particles are transported by wind, water, or ice.

The process by which sediments are deposited in a new location.

A type of rock formed from the accumulation and cementation of organic matter.

The process by which living organisms break down rocks and minerals, releasing nutrients.

The layer of unconsolidated material that covers the Earth's surface.

The process by which the Earth's surface is shaped by wind, water, ice, and gravity.

A low-lying plain along a river, formed by deposition of sediment.

A type of rock formed by the accumulation and cementation of sediment particles.

A type of rock formed from the precipitation of minerals from a solution.

A type of rock formed from the accumulation and cementation of organic matter.
