(Blank) refers to the mass of all living organisms on earth

Bio mass

A Bay mouth bar is a (blank) feature made of (blank)

Natural; deposited sand

Chesapeake Bay and Delaware Bay are

All of the above; associated with a submergent coast, former river valleys that were flooded by a rise, sea level, excellent examples of large estuaries

Density driven ocean circulation is also called (blank) circulation

Thermohaline

Them Bermuda high is a large persistent, high pressure system centered, roughly on the island of Bermuda and mid Atlantic. Air circulates clockwise around the high-pressure systems because of the Coriolis effect. Is there any connection between Atlantic Ocean currents in this weather feature?

Yes, north Atlantic circulation is approximately the same as the long-term average circulation of the Bermuda high

The daily title range is greatest during what period of the lunar cycle

A and C ; full moon and first quarter

The east and West Coast of the North America are dominated by (blank)) and (blank) current respectively

Warm; cold

The energy that creates surface ocean currents come from

Prevailing winds

The energy that drives surface currents, such as the Gulf stream comes from

Prevailing winds

The height length in period of a wave depend upon

All of these; the length of time the wind has blown, the fetch, and the wind speed

The movement of sand parallel to the shore

All of these; may create spits, is created by waves approaching at an oblique angle, is achieved by Longshore carts

What is the difference between the coastline and Shoreline?

The coast is the landward limit of ocean related landforms, the coastline is the line that separates the coast from the shore, and the shoreline is the ephemeral line that marks the interface between land and C

When Europeans first came to the New World, they were typically sales south and west to Canary Islands, then west to get to the west Indies. On their return, they would go north past the Leawood Islands and Canadian Maritime provinces before turning east towards Europe. Why did they choose this circular route?

This route followed both the prevailing winds and ocean currents speeding the trip along the distance

You’re walking along a rugged coastline in British Columbia Canada. As the tide goes out, you realize there was a beautiful flat surface that is nearly as smooth as a highway, and under lane by a 1 to 2 cm of gravel sitting on solid rock. The tide has exposed a

Wave cut platform

(Blank) our old, uplifted wave, cut platforms

Marine terraces

(Blank) currents are strong currents, perpendicular to the coastline; swimmers can easily avoid them by swimming parallel to the shore to clear the current before then swimming back into shore

Rip

As you go up in elevation, the atmosphere pressure

Decreases

Heat flows

From hot to cold

Important weather phenomenon typically occurs in the

Troposphere

In the outer most layer of the atmosphere, gas molecules can have a temperature of 1000°C because

Temperature defined as the average speed of which molecules move, and the molecules move rapidly there

Layton heat that is the energy source for many storms can be transported by

Water vapor

Ozone is important to humans because it

Absorbs ultraviolet radiation which is harmful to humans

Solar will strike the tropic of Capricorn and an angle of 90° on

The atmosphere requires most of his energy from

The Earth surface

The line separating the dark half of earth from delighted half is called the

Circle of illumination

The most layer of the atmosphere is the
