Continent jig-saw shapes when puzzled and combined together, formed one big continent - Pangea, and was separated by drifts. Fossil comparisons of different species were discovered into two different, separated continents in which when you combine them, they were one in the past. Seismic, volcanic, and geothermal activity are found along imagined plate boundaries. Plates were actually rubbing against each other as evidence is seen on the formed mountain ranges. Paleomagnetism, magnetic field placement in the layers of the rock are present. <span> </span>

To determine a change of elevation on a topographic map what type of math would you use?

Artemon [7]

Answer:

-subtraction

Explanation:

Elevation is the altitude of a place above a reference frame.

To find the difference between the elevation between two or places on a map, we perform a subtraction operation.

The differences in elevation is the subtraction of the two elevation values from one another.

For example if point A on a map is at 60m above sea level and point B is at 100m, the change in elevation is;

Change in elevation = Elevation of B - Elevation of A = 100m - 60m = 40m

Which natural event periodically weakens western surface ocean currents in the equatorial pacific ocean, resulting in a change i

densk [106]

El Niño is a natural event that periodically weakens the western surface of ocean currents in the equatorial pacific ocean. In an El Niño, the wind that pushes water around (which keeps the east warm and west cold) gets weaker making the ocean warmer, changing the air temperature and precipitation patterns in the United States.

Most of the time in the atmosphere, the upward-directed pressure gradient force is exceeded by the downward pull of gravity.

Lisa [10]

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.
