Answer:
The amount of rainfall from 1997 to 2006 changed through spiking.
Explanation:
In 1997-1998, the El nino years were happening, and there was a lot of rainfall. Then, the El nino event came back later in 2006, this time a bit stronger. So that is the reason why the rainfall had big spikes over these years.
hope this helps!
Answer: from 1997-1999 the rain was up then dropped to 4 inches then up to 5 inches and spiked up to 8 inches in 2000 and 2001. 2002 and 2003 it was 6 inches then 7, it spiked up again in 2004 to 10 inches and dropped in 2005-2006. almost every 2 years the rain spiked up for a year by 3 inches then dropped 2 inches

Answer:
1. Main sequence stars have different masses. The common characteristic they have is their source of energy. They burn fuel in their core through the process of fusing hydrogen atoms into helium.
2. Supergiants are among the most massive and most luminous stars. Supergiant stars occupy the top region of the Hertzsprung–Russell diagram with absolute visual magnitudes between about −3 and −8. The temperature range of supergiant stars spans from about 3,400 K to over 20,000 K.
3. Supergiants develop when massive main-sequence stars run out of hydrogen in their cores.
4. a supernova occur When the pressure drops low enough in a massive star, gravity suddenly takes over and the star collapses in just seconds. This collapse produces the explosion.
5. when a star has reached the end of its life and explodes in a brilliant burst of light

How might it benefit forensic scientists to smaller subcategories for fingerprints?
Answer: Once the fingerprints are captured and described, judicial physicists use a categorization structure to label the ruling class. The three elementary mark on finger patterns is Whorl, Arch, and Loop. There are more intricate categorization methods that further decay the pattern to plain arches or make camp arches. Loops grant permission be branching or ulnar.

Why are power plants so expensive?
(Please give an easy but whole explanation)
Answer:
Power plants are very expensive as their system is quite complex and must satisfy strict licensing and design requirements. To create a nuclear power plant, a team of highly qualified specialist must work together and the construction may take many years. Although power plants are expensive to build, they are cheap to run.

In conclusion, the amount of rainfall in 2004 was higher than the rest of the amounts in the years later and earlier than 2004. This shows that the amount of rainfall was high in 2004.
Dew point is the temperature at which water vapor in the air begins to condense into liquid water. The higher the dew point, the more moisture there is in the air. From the starting sounding in the simulation, change the temperature for each point between 800 hPa and 1,000 hPa to 40°C. Then, test how changing the two dew points closest to Earth’s surface (while keeping the temperature constant) affects whether a cloud forms and how big the cloud is if it does form. Describe what you observe, and explain why it occurs.
Answer:
Dew points indicate the amount moisture in the air. The higher the dew points, the higher the moisture content of the air at a given temperature. Dew point temperature is defined as the temperature to which the air would have to cool (at constant pressure and constant water vapor content) in order to reach saturation. A state of saturation exists when the air is holding the maximum amount of water vapor possible at the existing temperature and pressure.
When the dew point temperature and air temperature are equal, the air is said to be saturated. Dew point temperature is NEVER GREATER than the air temperature. Therefore, if the air cools, moisture must be removed from the air and this is accomplished through condensation. This process results in the formation of tiny water droplets that can lead to the development of fog, frost, clouds, or even precipitation.
Relative Humidity can be inferred from dew point values. When air temperature and dew point temperatures are very close, the air has a high relative humidity. The opposite is true when there is a large difference between air and dew point temperatures, which indicates air with lower relaitve humidity. Locations with high relative humidities indicate that the air is nearly saturated with moisture; clouds and precipitation are therefore quite possible. Weather conditions at locations with high dew point temperatures (65 or greater) are likely to be uncomfortably humid.

Locations with high relative humidities indicate that the air is nearly saturated with moisture; clouds and precipitation are therefore quite possible. Weather conditions at locations with high dew point temperatures (65 or greater) are likely to be uncomfortably humid.
As per the given scenario, the temperature for each point between 800 hPa and 1,000 hPa is changed to 40°C. This means that the temperature of the air at all those altitudes is the same.
What are dew points?Dew point is the temperature at which the air becomes saturated with water vapor, leading to the formation of dew, fog, or clouds when the temperature drops further.
Now, the two dew points closest to Earth’s surface are changed while keeping the temperature constant. Dew point is the temperature at which water vapor begins to condense into liquid water. Therefore, changing the dew point changes the amount of moisture in the air.
When the dew point is close to the air temperature, the relative humidity is high, and the air is almost saturated with water vapor. In such a case, if the dew point is raised even slightly, the air becomes saturated, and the water vapor condenses into liquid water.
On the other hand, if the dew point is lowered, the relative humidity decreases, and the air becomes drier. In such a case, the chances of cloud formation are reduced.
Therefore, if the dew point is raised close to the air temperature, a cloud forms. The size of the cloud will depend on the amount of moisture present in the air. The higher the dew point, the more moisture there is in the air, and the bigger the cloud will be.
