States might choose to cooperate at the regional or global level for all of the following reasons EXCEPT (2 points)A.) to gain regional political influence

B.) to engage in dispute resolution

C.) to assure basic human rights

D.) to encourage economic interaction

E.) to increase national sovereignty

Answers

The correct answer is - E.) to increase national sovereignty.

By cooperation on regional or global level the states do not, and can not really do anything about increasing the national sovereignty. The reason for that is that the national sovereignty is the matter of the state itself, its politics, policies, and handling of the situations in the country. The other countries with whom the state cooperates have nothing to do with it, nor it is their place to interfere in the national sovereignty of the other states, be it friendly states or not.

Explanation: answer e increase national sovereignty

1) Earth's crust is made up of relatively rigid plates that ride atop Earth's hot, semiliquid mantle. (2) The plates are called tectonic because they're in constant motion. (3) They can move because Earth's mantle is a very hot and semiliquid fluid called magma. (4) Volcanoes are a result of magma rising up or erupting through a plate, particularly where plate boundaries are moving against each other. (5) Also, when plates slide against each other, causing friction along adjacent plate boundaries, earthquakes frequently occur. (6) Therefore, we often find volcanoes and earthquakes along plate boundaries. (7) Plates may also collide. (8) When that happens, mountain ranges are formed. (9) For example, the collision of the plate carrying the Indian subcontinent created the Himalayan Mountains when it collided with the Asian plate.2.

Describe where you can find a meteor

Answers

atoms are what you can find in meteor if you go to a science lab and take tests
A meteoroid is a small rock or particle of debris in our solar system. They range in size from dust to around 10 metres in diameter (larger objects are usually referred to as asteroids).

A meteoroid that burns up as it passes through the Earth’s atmosphere is known as a meteor. If you’ve ever looked up at the sky at night and seen a streak of light or ‘shooting star’ what you are actually seeing is a meteor.

A meteoroid that survives falling through the Earth’s atmosphere and colliding with the Earth’s surface is known as a meteorite.

The fastest meteoroids travel through the solar system at a speed of around 42 kilometres per second (26 miles per second).

The Earth’s atmosphere experiences millions of meteors every day.

Meteors are easier to see during the lower light conditions of night.

A small percentage of meteoroids fly on a path that goes into the Earth’s atmosphere and then back out again, they are known as Earth grazing fireballs.

When many meteors occur in a close time frame in the same part of the sky it is called a meteor shower.

Around 500 meteorites reach the Earth’s surface every year but of those only around 5 ever make it to scientists for study.

Meteorites that are observed as they fall through the Earth’s atmosphere and later recovered are called ‘falls’, all others are called ‘finds’. To this date there have been around 1000 collected ‘falls’ and 40000 ‘finds’.
