Which Describes the Composition of the Ocean Floor

A- elevation B- relief C- slope. It began as an eruption on the floor of the Pacific Ocean.

Ocean Basin Earth Feature Britannica

Magma Consists of Three Components Liquid portion the melt The liquid is a silicate melt not water based Composed of mostly Si and O.

. Solids if any are crystals of silicate minerals Volatiles - dissolved gases in the melt that volatilize from the magma at low near-surface pressures Most common volatiles in magma. English Grammar Composition. B hot mantle material rises upward creating volcanic islands.

The Atlantic Ocean occupies an elongated S-shaped basin extending longitudinally between. Ridges in the middle of the ocean are places where A one plate slides under another returning older crust to the mantle. Remember me on this computer.

Composition refers to the rocks specific mineralogy and chemical composition. 22 A to Fig. Spiteful definition full of spite or malice.

The Atlantic Ocean is the second-largest of the worlds five oceans with an area of about 106460000 km 2 41100000 sq mi. A- erosion B- abrasion C- chemical. Cooling history is also related to changes that can occur to the composition of igneous rocks.

The volcanic cone grew as recurrent eruptions built up layer after layer of basalt flows. Texture describes the physical characteristics of the minerals such as grain size. The island that we know today as Hawaii is thought to be between 300000 and 600000 years old.

It covers approximately 20 of Earths surface and about 29 of its water surface area. This relates to the cooling history of the molten magma from which it came. Which process is responsible for changing the composition of rock.

The structure of the seabed of the global ocean is governed by plate tectonicsMost of the ocean is very deep where the seabed is known as the abyssal plainSeafloor spreading creates mid-ocean ridges along the center line. This is represented by the addition of red spheres and blue cubes to the box from Fig. Which word describes this 250-meter measurement.

The seabed also known as the seafloor sea floor ocean floor and ocean bottom is the bottom of the oceanAll floors of the ocean are known as seabeds. About 100000 years ago it is thought to have grown tall enough to emerge from the ocean as an island. Close Log In.

Change to the height of sea level both globally and locally relative sea level change at seasonal annual or longer time scales due to 1 a change in ocean volume as a result of a change in the mass of water in the ocean eg due to melt of glaciers and ice sheets 2 changes in ocean volume as a result of changes in ocean water density eg expansion under warmer. Enter the email address you signed up with and well email you a reset link. The gently sloping submerged surface that extends from the shoreline toward the ocean basin floor is the continental a.

MS-PS1-1 Develop models to describe the atomic composition of simple molecules and extended. Plastics in the marine environment are of increasing concern because of their persistence and effects on the oceans wildlife and potentially humans Plastic debris occurs on coastlines in Arctic sea ice at the sea surface and on the sea floor 7 8Weathering of plastic debris causes fragmentation into particles that even small marine invertebrates may ingest. Salinity describes how much salt is dissolved in a sample of.

Introduction to the Ocean Floor. C hot mantle material rises upward and spreads sideways pushing the plates apart.
