What causes air masses to move?

When prevailing westerlies shift directions and move toward the west.
Weather conditions change rapidly to produce storms.
A collision takes place between two natural wind patterns.
Long, narrow bands of wind blow in the upper atmosphere.

Answers

Answer:-The cause of the air masses to move is: The current of air and wind causes the air masses to move. The change in the air masses is the reason for the change in the weather.

Explanation:

Air masses are moved by differences in air pressure, which is caused by uneven heating of the earth's surface by the sun. This creates areas of high and low pressure, and air masses will move from areas of high pressure to areas of low pressure.

What is air mass ?

An air mass is a large body of air in the atmosphere that has similar temperature and humidity characteristics throughout its horizontal extent.

Air masses are classified based on their source region, which can be over land or water and in different latitudes. As air masses move from their source regions, they can bring changes in weather conditions to the areas they move over.

The movement of air masses can also be influenced by the rotation of the earth, which causes the Coriolis effect. This effect causes air masses in the Northern Hemisphere to be deflected to the right, and air masses in the Southern Hemisphere to be deflected to the left.

The collision of two air masses with different properties, such as temperature and humidity, can also cause movement and create weather conditions.

If The DNA Isn’t right whatever it makes would be completely mutated
Error occurrence in the formation of RNA and arrangement of the hydrogen bases will cause changes in the arrangement of amino acids thus an erroneous protein structure which will negatively effect the process or trait it is responsible for. Example, melanin a protein responsible for eye color and skin color,if its structure is inexact it will probably cause disorders in whatever trait is responsible from (that explains why some people have two different eye colors).In conclusion genes or dna must be unchanged and mutations will lead to negative consequences and disabilities.

Which of these organisms is not a chordate? earthworm snake sea squirt human​

Answers

Answer:

Humans

Explanation:

Humans are not chordates because humans do not have a tail. Vertebrates do not have a notochord at any point in their development; instead, they have a vertebral column.

The organism that is not a chordate is the earthworm.

What are chordates?

Chordates are a group of animals that possess four distinctive anatomical features at some point during their life cycle: a notochord, dorsal nerve cord, pharyngeal slits, and a post-tail. These features set chordates apart from other animal groups and have been critical in their evolutionary success.

Chordates include a wide variety of animals, ranging from fish, amphibians, and reptiles to birds and mammals, including humans. Chordates are found in aquatic environments such as oceans, rivers, and lakes, as well as on land, and play a critical role in many ecosystems as both predator and prey.

The needle of the compass is pointing toward the magnetic north pole of Earth. What would cause the needle of the compass to point toward the east? Explain why.

Answers

A compass needle points north because the north pole of the magnet inside it is attracted to the south pole of Earth's built-in magnet.

Compasses always point north. The magnetic pin in the compass aligns with the top of the planet's magnetic field and points in that direction. A broken compass points east.

Why does a broken compass points east?

A strong magnetic field nearby may be the reason a compass points East. A compass may point in that direction if anything has a stronger magnetic attraction than the planet's magnetic field. Power lines, huge batteries, and magnetic metals like iron can cause interference. Their electromagnetic fields decrease quickly with distance.

A compass may point east if the needle's free movement is hindered. Compass needles are free-floating. It can't face North if it's damaged, bent, or blocked by debris. This may explain why the compass needle won't turn.

Identify each wave interaction based on how it changes direction.
The wave changes direction as it bends and scatters.



The wave changes direction as it changes its speed.



The wave changes direction at an angle equal to the angle of incidence.

Answers

The wave changes direction as it bends and scatters. - Refraction because it changes in direction of the waves that occur when waves travel from one medium to another.

The wave changes direction as it changes its speed. - Refraction because the waves change speed when they pass across the boundary between two different substances, such as the light waves refracting when they pass the air to glass.

The wave changes direction at an angle equal to the angle of incidence. -reflection because if a wave hits a mirror at an angel of 36, and it will be reflected at the same angel of 36.

Explanation: Hope this helps, Have a good day!

The wave changes direction as it bends and scatters is known as reflection, the wave changes direction as it changes its speed is known as refraction, and the wave changes direction at an angle equal to the angle of incidence is diffraction.

What are wave interactions?

When waves interact, they can change direction in different ways. Here are the three ways that waves can change direction:

1. Reflection: The wave changes direction at an angle equal to the angle of incidence. This happens when a wave hits a barrier or a surface that it can't pass through. The angle of incidence is the angle between the incoming wave and the normal, which is an imaginary line perpendicular to the surface.

2. Refraction: The wave changes direction as it changes its speed. This happens when a wave passes from one medium to another, and the speed of the wave changes. When this happens, the wave bends towards or away from the normal, depending on the direction of the change in speed.

3. Diffraction: The wave changes direction as it bends and scatters. This happens when a wave encounters an obstacle or a gap in a barrier that is comparable in size to the wavelength of the wave. When this happens, the wave bends around the obstacle or spreads out through the gap.

In 1918, warring nations made peace after four years of "The Great War," now referred to as World War I. The United States retreated somewhat from global politics. Instead, the country focused on its own economic and technologic growth. The 1920s were a prosperous time for many Americans. The economy was booming, and many people made a lot of money. The decade is commonly known as the Roaring Twenties. People focused on having fun, spending time at cinemas and jazz clubs. Consumerism was on the rise. For the first time, factories built new products like cars and telephones for a wide market. With newfound wealth, people were able to buy these luxury items. Though the economy was doing well, mostly managers and business owners profited. Workers were not always so lucky. The gap between the rich and the poor grew. Those who still could not afford fancy new consumer products bought on credit. They took out loans on the promise that they would pay back the money they borrowed. Many people also borrowed money to invest in the stock market. They bought shares of businesses in order to make a profit if the company had success. All this borrowing meant that people saved very little and spent money that they ultimately did not have.
