Answer:

Sample Response: First, I wrote each ratio as a fraction. Then I found a common denominator of 20. The fraction 4/10 is 8/20. Comparing numerators, 8 is less than 12, so the ratio 4:10 is smaller.

The given information is expressed in ratio. However, a ratio is basically a fraction. So, 4:10 is just equal to 4/10 or 2/5 in simplified terms. Similarly, 12:20 is just equal to 12/20 or 6/5 in simplified terms. The smaller ratio is 2/5 because the numerator is less than the denominator. So, it follows that the answer is less than 1. The other ratio has a much greater numerator. So, we would expect that that would be greater than 1.

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.

What mountain range is between the black and caspian seas

mihalych1998 [28]

Answer:

Caucasus Mountain Range or Caucasus Mountains is between the black and caspian seas.

Explanation:

This mountain is a great barrier that extends for 750 miles and its tops exceed 4500 meters. It is located between the Black Sea and the Caspian Sea.

It has two mountain ranges: the Great Caucasus, which is the largest mountain range and extends for 1200 km, and the Lesser Caucasus which is 600 km long.

This great mountain range was created by the clash between the Arab plate and the Eurasian plate approximately 28 million years ago. Due to the constant movement of plates, it is a region prone to continuous strong earthquakes although it does not have volcanic activity despite the existence of some stratovolcanoes.

Can someone pls help!!! this test is important!!

I am Lyosha [343]

Answer:

Mountain, Canyon, Delta

Explanation:

The uppermost box would be mountain.

The box below that one would be canyon.

And the farthermost box to the right would be delta.

If you thought about it, changing those circles to make them 3D is like stacking layers on top as they get smaller, this would form something that looks like a mountain.

Water typically runs through a canyon and the lines appear to be separating for the water.

Deltas are wetlands that form from rivers emptying their water into another body of water. If you were to look up an image of a delta that would make it easier to understand, it also looks like what the image provided is trying to demonstrate.
