Answer:

Ture

Explanation:

The pressure gradient is the force that is produced due to the rotation of earth pressure cells that creates lighter air to move upwards and heavier to move downwards due to the difference in densities of air.

As the air above consists of lighter elements the oceanic air mostly consist of diatomic molecules of oxygen and nitrogen thus containing a large amount of water vapor, all these molecules have a mass that are pulled down by the gravity and this pull of gravity on columns of gas applies a force what we see an atmospheric pressure.

The gas particles and molecules of heavy and denser matter get stuck at the ground, similarly, as the air cools is descends and warm air rises. Thus upwards and downward motion of air causes convergence and divergence of molecules.

I don’t understand how you do f and g

sveticcg [70]

Answer:

144 degrees

27 degrees

Explanation:

f) So angle EBD is angle 5, which is 36 degrees. Angle DBC is angle 1 and is 108 degrees. We need to find angle EBC or 5 + 1.

So we know that EBC is angle 5 + 1, we can do angle 5 plus angle 1 or:

36 degrees + 108 degrees = 144 degrees.

Angle EBC is 144 degrees.

g) So we know angle EBF or angle 4 + 3 is 117 degrees. We need to find angle ABE or angle 4. We know that angle 3 is 90 degrees because of BF is perpendicular to AC. So now we can find angle ABE or 4:

117 degrees minus 90 degrees = 27 degrees

Angle ABE is 27 degrees.

Explain why the town in canada is colder than the amazon village

tigry1 [53]

Answer:

Canada is colder because it is up North. It isn't as humid as it is in the south so it makes the air more dry and thin, making it colder. Where in the Amazon, it is warm and moist because it is by the equator and is near the tropics.

Explanation:

I hope this can help... I just answered with what I learned in science...

The movement of a tectonic plate away from a mid-ocean ridge can be measured by the orientation of the _______ field.

Crazy boy [7]

Answer:

geomagnetic field.

Explanation:

The earth magnetic field can be likened to a bar magnet with a North and South pole. It originates from the movement of molten iron and nickel in the outer core.

At every point in time, the magnetic field orientation can change. We must note that the magnetic north lies close to that of geographic north axis of the earth.

Around the mid-oceanic ridges, new materials are brought to the surface. These new materials can contain magnetic minerals such as haematite which are capable of being magnetized as a result of the prevalent magnetic field of the earth. As different materials are brought up, the magnetic minerals preserves the details of the magnetic field at that point in time. Using this information can know the orientation of the magnetic field at any point in time if the magnetic history chart of the earth is constructed. Oceanic ridges becomes older as they move away from the divergent margins.

The region labeled with the number 3 on the map above is best known for being what type of landform? A. a plain B. a plateau C.

Lorico [155]

The correct answer is a plateau. A plateau is a flat, elevated land form that rises sharply above the surrounding area on at least one side. It occurs on every continent and take up a third of the Earth's land. Many plateaus form as magma deep inside the Earth pushes toward the surface but fails to break through the crust. Instead, the magma lifts up the large, flat, impenetrable rock above it.
