Earth Science Chapter 13

the cycling of nitrogen compounds through the atmosphere

perpetually dark and cold

deep, flat zones of the ocean basins

occupied by animals living between the high and low tide marks

Mean Sea Level (MSL) is slowly rising around the globe

Suitable for drinking

The higher the salinity of the water the higher the freezing point

Seamounts are submerged volcanoes and hills

consist of tiny single celled animals and plants and other microscopic particles

Seawater contains about 300 g of salt per kg of seawater

beginning of the deep ocean basin

the mathematical model of the earth that approximates the average surface elevation

The oceans are divided into 5 different ocean basins

Carbon cycle refers to the cycling of Nitrogen compounds through the atmosphere

area where only the highest tides or storm waves reach

smooth transition from slope to the floor

Oceans near the equator are warmer than those nearest to the poles

The speed of sound waves in water is much faster than their speed in air

a coral reef that is separated from the mainland by a lagoon

Lightning is a natural source of nitrogen that does not involve nitrogen fixing organisms

vast bodies of salt water that separate the continents

Coral reefs are found in shallow water due to their need for light

Pelagic organisms do not live on the bottom of the ocean (squid)

What day did God create land and arranged the supercontinent

Marine scientist and engineers

Refers to anything having to do with oceans

Coral reefs are often referred to as...

the Pacific Ocean atoll could have formed when a volcanic island collapsed into a caldera or a shallow seamount sank

ever changing place that extends underwater beyond the shore

submerged edges of of continental plates

Varies from place to place

Surface water is typically much richer in oxygen than the deeper zones

The deepest part of the ocean is approximately 11,000 meters

Guyots- underwater volcanic vents

Island arcs line the lip of trenches and subduction plates

bright and clear zone of the open ocean

A large section of ocean surrounded by land or islands

is not penetrated by light

occupied by animals between the low tide mark and the edge of the continental shelf
