Some scientists say it is because of global warming. global warming is caused by what is believed to be us polluting the atmosphere. When we pollute the atmosphere with smoke, and gas, and other harmful things, it traps the heat from the sun which makes it feel hotter. Imagine it like the Earth covered up with a blanket. When you get hot, you would want to take the blanket off. Well, the Earth cannot take off that blanket when it gets hot. It just keeps getting hotter and hotter. Have you ever been in a greenhouse? If you have, you would know it is very hot. The Earth's atmosphere is like a greenhouse. It takes in the sun heat and traps it inside. Of course our atmosphere releases some heat to make the atmosphere at a moderate temperature and not boiling hot. Global warming is making the Earth much warmer and when the air gets more heated up, the atmosphere doesn't release enough to keep it at that normal temperature.
The sand has a higher conductivity.
At higher altitudes, the air is less dense and contains fewer molecules to trap heat, so it can feel colder rather than hotter. However, the sun's rays can still feel more intense due to less atmosphere to scatter them, making it feel warmer in direct sunlight.
20°C is hotter than 20°F. 20°C is equivalent to 68°F.
The evaporation of your perspiration is lessened when there is high humidity, making it more difficult for the body to cool itself off. It is not the act of sweating that cools you off, but the evaporation of the sweat.
20 degrees Celsius is hotter than 10 degrees Celsius.
because intensity of rays is more in afternoon
The sun's corona has a temperature of 1,799,540 to 5,399540 Fahrenheit, which is significantly hotter than solar rays - the Sun's solar radiation is said to have a temperature of about 9980 Fahrenheit.
Gamma rays are typically hotter than plasma. Gamma rays are high-energy electromagnetic radiation, while plasma is a state of matter where atoms have been stripped of their electrons. Gamma rays can have temperatures reaching billions of degrees, while plasma temperatures are typically in the millions of degrees.
"The solar rays are hotter on the equator than in the northern hemisphere."
The sand has a higher conductivity.
The answer to the brain teaser "What is the day before today if two days from now will be the second day this week that will be hotter than today" is Friday. This is because if today is Friday, the day before today, which is Thursday, will be hotter than today (Friday), and two days from Friday is Sunday, which will be the second day that is hotter than Friday.
It is likely hotter in April than in December t is because the rays of sunlight that hit the ground in April is at the angle of 90 degrees while in December the angle of the sunlight is at 52 degrees.
At higher altitudes, the air is less dense and contains fewer molecules to trap heat, so it can feel colder rather than hotter. However, the sun's rays can still feel more intense due to less atmosphere to scatter them, making it feel warmer in direct sunlight.
The sand feels hotter to touch than the towel because sand has a lower heat capacity than the towel, which means it heats up faster when exposed to the sun. This is why the sand can feel hotter even when they are both under the same sun.
Everything hotter than a red giant produces some UV radiation.
Obviously the angle of incidence is different. The oblique rays spread their energy over a larger area of the surface than vertical (also called perpendicular or normal rays)
