Which state would be the safest if you wanted to avoid death by lightning?

Answers

Washington
The mixture of cold water and dry air fails to produce thunderstorms. With that being said, the West Coast still experiences storms, just significantly less than any other geographical area.

Washington is the safest if you wanted to avoid death by lightning.

What is lightning?

A natural electrostatic discharge called lightning occurs when two electrically charged regions, one on the ground and one in the atmosphere, momentarily neutralize one another. This results in the instantaneous release of an average of one gigajoule of energy.

A vast variety of electromagnetic radiation, including heat from the accelerated migration of electrons and bright bursts of visible light in the form of black-body radiation, may be produced by this discharge. Thunder is a sound produced by a shock wave created by lightning, which is created when the pressure of gases nearby suddenly rises.

Thunderstorms cannot form when dry air and cold water are together. Despite this, storms still occur on the West Coast, albeit far less frequently than in any other region.

Hence, Washington is the safest if you wanted to avoid death by lightning.

Which is an example of climate? a sudden snowstorm resulted in subzero temperatures and 30 inches of new snow. a week of rain caused widespread flooding in seattle. record-breaking low temperatures caused a sudden freeze one day in des moines. in southern california, temperatures are generally mild and rainfall is low?

Answers

Out of those examples, climate: In Southern California, temperatures are generally mild and rainfall is low.

Answer:

B. In southern California, temperatures are generally mild and rainfall is low.

Explanation:

A climate is defined as a long term average weather condition that stays constant for example for 30 years. And the most commonly found climatic variables are the humidity, rainfall, and the pressure and wind belts. These may be in the form of polar, tropical, and temperate climates, etc. Thus they remain stable and have general patterns of variation. The climate of California is generally mild with low rainfall as California has a dry, hot summer and a mild winter as the nearness to the coasts. Thus this shows the climate is for a long period and the season is for a short or temporary period. The high mountain rangers have snow in the northern sides and the southernmost region lack rainfall and have near desertic conditions.

The term fresh water refers to water with low _______.

Answers

The term fresh water refers to water with low salt content. This is because life on Earth has had to adapt different hydrologic conditions and therefore it affected most of our topography. The last ice age had so much glaciers and snowpacks. Now, little of the ice has left in parts of the Atlantic and Antarctic region. Glaciers are the huge storage of freshwater. That is why when you swim in a fresh water, you feel that your movement is slow and heavy compares to the ocean. Also, fresh water has a higher density compared to ocean.

Which is a common first indicator of an approaching thunderstorm?

Answers

The first indicator of an approaching thunder storm is THE BUILD UP OF DARK CLOUDS. A thunder storm is a storm with lighting and thunder; it is usually produced by heavy rain, gusty wind and cumulonimbus cloud. Thunder storm is made up of moisture, unstable air and lift.
Final answer:

The first signs of an approaching thunderstorm can be a change in weather conditions like increase in wind, darkening skies, dropping temperature, and distant thunder or lightning. Also, the formation of a towering cumulonimbus cloud is a significant indicator of a thunderstorm.

Explanation:

A common first indicator of an approaching thunderstorm is a noticeable change in the weather. This could include increasing wind, darkening skies, and a sudden drop in temperature. Additionally, you may observe distant lightning or hear far-off thunder, as these are also known as the precursor signs of a thunderstorm. In some situations, the atmosphere might feel stiflingly hot just before a thunderstorm because of the humid conditions which often precede such storms.

Another significant indicator is the formation of a large, towering cloud, known as a cumulonimbus or thunderhead cloud. These types of clouds are driven by convection and can reach high into the stratosphere, signaling an impending thunderstorm. They are associated with severe weather conditions including heavy rain, lightning, and even tornadoes. Observing the sky carefully and understanding these early signs can help individuals seek shelter and stay safe in the advent of a thunderstorm.
