Answer:
The plates have moved across Earth’s surface for hundreds of millions of years. As the plates move, the continents on them move, too. This movement is called continental drift.
Scientists think that it takes about 500 million years for all the continents to join together into one big continent—or supercontinent—and then break apart again. A number of supercontinents have formed and broken apart on Earth over time. The most recent supercontinent, called Pangea (or Pangaea), had formed by about 270 million years ago. Pangea lay across a plate boundary. Slowly, Pangea broke apart at this boundary. Rising magma filled in the space, which eventually became the floor of the Atlantic Ocean.
One piece of Pangea included parts of what are now North America, Europe, and Asia. This piece, called Laurasia, drifted north. The other piece of Pangea included parts of what are now Antarctica, Africa, South America, and Australia. This part, called Gondwanaland, drifted south. Eventually Laurasia and Gondwanaland broke apart, too. The continents then slowly moved to the places they are now.
The continents continue to move today. Scientists believe that in about 250 million years they will join together again.
Explanation:
The Pinnacle Mountain are west of Little Rock, Arizona.
Both are catastrophic, so I would pick neither, but the beginning may be more enjoyable, because you get to live. At the end of the world you will most likely die.
Answer:
- Interaction with land
- Conctact with colder water
- Strong vertical wind shear
Explanation:
- The interaction with land: a hurricane needs evaporation from the ocean surface to survive, when it touches land the hurricane is separated from its energy source since the air masses over the ocean are drier, less moisture is carried into the storm and air is cooled and then sinks disrupting hurricane's circulation.
- Getting in contact with colder water: when a hurricane moves northward out of the tropical ocean into mid-latitudes, it begins to get in contact with colder water, this makes it lose the warm water source, less moisture is evaporated into the atmosphere to supply clouds and this weakens the storm.
- Strong vertical wind shear: a change in wind direction or speed with height can enhance the mixing of drier environmental air into the storm eyewall leading to a column of cool air that rapidly sinks into the grounds, this inhibits the intensification of the hurricane. This kind of wind shear can be generated by fast upper-tropospheric winds.

Explanation:
Radiation means ‘energy that is transported from one spot to another without the need of direct contact between the two locations’, Light in each carries a different amount of energy, this is what we call electromagnetic radiation or electromagnetic waves. Gamma rays are the most energetic, and radio is the least.
<em>In order from longest to shortes wavelenghts we have:</em>
- Radio waves: they are made by various types of transmitters, given off by stars, sparks, and lightning, they have the lowest frequencies (longest wavelenghts) in the electromagnetic spectrum and are used mainly for communications.
- Microwaves: they are extremely high-frequency radio waves (Their wavelength is usually a couple of centimeters) made by various types of transmitters.
- Infra-red waves: they are just below visible red light in the electromagnetic spectrum, they're given off by hot objects.
- Visible lights is the tiny part of the electromagnetic spectrum our eyes can detect.
- Ultra-Violet: this light is given off by the Sun in large quantities. We call it "UV" for short and can also be used to kill microbes.
- X-rays: they are very high-frequency waves that carry a lot of energy. They will pass through most substances, and this makes them useful in medicine and industry to see inside things.
- Gamma rays: they are given off by stars and by some radioactive substances. They are extremely high-frequency waves (the shortest wavelength) and carry a large amount of energy. They pass through most materials.
In the image, I annexed you can see the electromagnetic spectrum with the type of radiations from the shortest to the longest wavelengths.
