How would you describe the lines of longitude on a map

1 answer:

3 0

Longitude on a map is like vertical mapping lines on Earth which are well known as "meridians". One way to visualize this would be to think of splitting hula-hoops in half, then vertically, up and down, assembling them, with one positioned at the North Pole and one the South. Longitude lines show a numerical way to measure or show how far a location is east or west of the vertical line known as the Prime Meridian. The Prime Meridian runs vertically, north and south, over the British Royal Observatory, located in Greenwich England, from the North Pole to the South Pole.

What happens during the entire fusion process in the Sun? Two hydrogen nuclei come together to produce one helium nucleus and tw

Hoochie [10]

Answer: Two hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released.

Explanation:

All stars (including the Sun) at birth begin to fuse two hydrogen nuclei to form helium through nuclear fusion.

In this sense, nuclear fusion is the union of two light atoms, releasing energy in the process, which is the cause of the great luminosity of a star. Especifically, the hydrogen nuclei will begin to fuse, generating helium nuclei in the process and releasing huge amounts of energy.

To unerstand it better:

To shine, the stars transform their hydrogen into helium by means of nuclear fusion. When at half of its life a star is without hydrogen, the nucleus becomes entirely helium and the star declines, becoming colder and brighter due to the energy generated by the nuclear reactions, then the star begins to contract.

Nevertheless, if the star is bigger, this helium will be also consumed and the nucleus transformed in Carbon, then in Oxigen, and so on. Being the last transformation Iron until the star delivers all its energy.

KatRina [158]

Answer:

This is because of isostatic adjustment.

Explanation:

The mountains of the Himalayas keep growing because of the isostatic adjustment. it allows for a gravitational balance in the Himalayan mountain region, which causes tectonic plates to float below these mountains. This fluctuation occurs in the densest part of the asthenosphere. This density, together with the force of gravity, causes an increase in the height of the tectonic plate that sinks more and more. As the tectonic plate sinks, inversely, this plate rises, when its weight decreases, and it is this rise that causes the mountain to grow.

Many times a map scale will show distances in both miles and

fiasKO [112]

The correct answer is - kilometers.

Very often, the map scale is showing distances in both miles and kilometers. The reason for this that the majority of the countries in the world use the metric system, thus the kilometers are a must, but also there countries that do not use this system, thus they include the miles. In this way, the map scale can be used by people that both use and not use the metric system in their daily lives.

The map scale is a very important element on the maps. Its purpose is to enable the reader of the map to be able to measure the distance from one place to another, thus to be aware of the real distance in the real space.

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.
