B)solid ground found in the tundra
C)all of the above
D)small pieces of ice and snow

Answers

Answer:

A)a mixture of solid particles of liquid droplets found in the air

Explanation:

Particulate matter is a mixture of solid particles or liquid droplets found in the air. They are usually quite harmful and cause pollution to the environment.

These particles remain suspended for a long period of time in the air. Examples are dust, fine ash,  and water droplets. Particulate matter is usually a product of human activities. At times,  they could result from natural causes such as volcanic activities. Most of these particles are the common causes of lung cancer and some respiratory diseases.

  Solid ground found in the tundra is called permafrost.

  Small pieces of ice and snow are known as sleets.

 

So, a mixture of solid particles or liquid droplets found in the air is known as particulate matter.

In general, what is true of the alpha star in a constellation?
Group of answer choices

It is the westernmost star in the constellation.

It is the easternmost star in the constellation.

It is the star that is closest to Earth.

It is the brightest star in the constellation.

It is the reddest star in the constellation.

Answers

Answer:

An alpha star is the brightest star in the constellation.

Explanation:

The first option is not correct because this type of star is not identified as such because of its location in the constellation.

The second option, as the first one, is not correct because the location of this type of star has nothing to do with its identification as such.

The third option is not correct because the distance from Earth is not taken into account when a star like this is identified.

The fourth option is correct because an alpha star is a star that is brightest in the constellation, and it can be located anywhere in it, and it can be of any color a star can be.

The fifth option is not correct because the color of the star can be of any type, but what matters the most is how bright it is compared to the other stars in the constellation.

If a ship is sailing on an ocean and it is 2:00 pm at the prime meridian and 10:00
am on the ship, what is the longitudinal location of the ship? [Hint:longitude can be only E or W]

Answers

Answer:

The longitude of the location of the ship is W

Explanation:

Here we have the time at the prime meridian as 2 pm while the time at the ship is 10 am

What this means is that the prime meridian is 4 hours ahead of the time of the location of the ship.

Geographically, whenever a location is east of the prime meridian, it is ahead of the prime

meridian on time

If however a location is west of the prime meridian, the prime meridian is ahead of it on time

In this question, we can see that the prime meridian is ahead in time, so automatically the location is west of the prime

meridian

So therefore, its longitude is W

To determine, if a ship is sailing on an ocean and it is 2:00 pm at the prime meridian and 10:00 am on the ship, what is the longitudinal location of the ship, the following logical reasoning must be performed:

The time zones move across the world map from left to right, that is, from west to east. Thus, the west will always be a smaller time zone than the east.

Therefore, if it is 2 PM (14:00) at the prime meridian and 10 AM on the ship, the ship is west of the prime meridian.

How volcanoes are formed?

-When rock from the mantle melts, moves to the surface through the crust, and releases pent-up gases, volcanoes erupt. Extremely high temperature and pressure cause the rock to melt and become liquid rock or magma. When a large body of magma has formed, it rises thorugh the denser rock layers toward Earth's surface.
