What is a result of a seasonal change?
What is a result of a seasonal change?
Explanation: Seasonal changes in precipitation and temperature affect soil moisture, evaporation rates, river flows, lake levels, and snow cover. Leaves fall and plants wither as cold and dry seasons approach;these changes in vegetation affect the type and amount of food available for humans and other organisms.
What does seasonal change mean?
: the change from winter to spring, spring to summer, etc.
What is an example of a seasonal change for fall?
For example, in the fall, when the days start to get shorter, the trees sense that there is less sunlight. The plant is stimulated, and it sends messages telling the leaves to change colors and fall. This is an example of photoperiodism, the reaction of organisms, such as plants, to the length of day or night.
How do seasons affect our lives explain with examples?
Seasons affect many parts of daily life. Climate, weather and the change of the seasons affect much of what we do each day. The change of seasons allows for many different types of work, food, celebrations and recreation. Plants and animals also change their ways with the seasons.
What is the importance of seasons?
Learning about the seasons helps children understand the passage of time and teaches them about change. While some seasonal changes are more obvious (like changes in the weather), there are many important subtle differences related to each season, like changes in the type of food that is available.
How does the weather affect human activities?
Weather has a profound effect on human health and well-being. It has been demonstrated that weather is associated with changes in birth rates, and sperm counts, with outbreaks of pneumonia, influenza and bronchitis, and is related to other morbi dity effects linked to pollen concentrations and high pollution levels.
How does fog impact human activities?
Fog occurrence impacts a wide variety of human activities worldwide. Reduced visibility in fog quickly impacts our ability to drive, move over water, fly, and transit land by train. In each case the inability to see well, or to see an adequate distance ahead, is compromised by both fog and the speed of motion.
How does rainfall affect human activities?
However, too much precipitation can also have a negative impact on human activities, business and industry, agriculture, and the environment. For example, too much rain or snowmelt (water from melted snow) at one time can lead to flooding. Living organisms, including crops, can drown in floodwaters.
Do you live longer in warm climates?
In addition, warmer climates might allow people to live longer, according to some studies. Stanford University researchers found that warmer conditions over a period of time in the United States lowered the mortality rates, compared to the winter months, when the death rates peaked.
What is the healthiest place to live in the world?
Spain
Which country has worst weather?
Countries With the Worst Weather
- United Kingdom The United Kingdom of Great Britain and Northern Ireland, commonly shortened to United Kingdom, UK or Britain is a Sovereign State located of the Northwestern coast of Europe.
- Russia Russia, known as the “Russian Federation”, was formed on Dec 25, 1991.
Where is the most dry place on earth?
The driest place on earth officially is in the Atacama Desert in Northern Chile and southern Peru, in western South America (Figure SM4.
Is there any place on earth where it has never rained?
The driest place on Earth is in Antarctica in an area called the Dry Valleys, which have seen no rain for nearly 2 million years. There is absolutely no precipitation in this region and it makes up a 4800 square kilometer region of almost no water, ice or snow.
What is the driest city in the world?

What country has the worst humidity?
When weather fronts come in off the warm waters, it gets very hot, and very sweaty. The highest ever recorded was Dhahran in Saudi Arabia in 2003, when the ultra-high humidity made 42 degrees Celsius feel like 81 degrees.
What is the lowest humidity on Earth?
The world’s lowest recorded relative humidity value occurred at Coober Pedy in the South Australia desert when the temperature was 93 degrees and the dew point was minus 21 degrees producing a relative humidity of 1 percent.
Is 0% humidity possible?
The concept of zero percent relative humidity — air completely devoid of water vapor — is intriguing, but given Earth’s climate and weather conditions, it’s an impossibility. Water vapor is always present in the air, even if only in trace amounts.
Can 100 humidity kill you?
No. The humidity in air, even if “extremely humid” at room temperature is still lower than the humidity inside the lungs, which is saturated at body temperature.
What happens when humidity is 100%?
A reading of 100 percent relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the possibility of rain. If the air is at 100 percent relative humidity, sweat will not evaporate into the air.
Is humid air good for lungs?
Breathing in humid air activates nerves in your lungs that narrow and tighten your airways. Humidity also makes the air stagnant enough to trap pollutants and allergens like pollen, dust, mold, dust mites, and smoke. These can set off your asthma symptoms.
Can you have 100% humidity?
Surprisingly, yes, the condition is known as supersaturation. At any given temperature and air pressure, a specific maximum amount of water vapor in the air will produce a relative humidity (RH) of 100 percent. Supersaturated air literally contains more water vapor than is needed to cause saturation.
What is a good humidity level?
30-50%
