When direct sunlight heats the sidewalk, the concrete material of the sidewalk absorbs the heat energy and warms up. This causes the molecules within the concrete to move faster, increasing the overall temperature of the sidewalk. The sidewalk then radiates this heat back into the environment, contributing to urban heat island effect.

What is happening when direct sunlight heats the sidewalk?
When direct sunlight heats the sidewalk, the concrete absorbs the sun's energy. This energy increases the temperature of the sidewalk by causing its particles to vibrate more rapidly, resulting in the sidewalk feeling hot to touch.
Is direct sunlight heats the sidewalk an example of radiation Yes or no answer?
Yes.
What is the effect of direct and slanted sunlight on temperature?
Direct sunlight tends to raise temperatures rapidly due to its high intensity, while slanted sunlight has a less intense effect, leading to more gradual warming. Direct sunlight heats surfaces directly below it, whereas slanted sunlight covers a wider area and may result in more uniform warming.
What transfer of heat is a burner on a stove heats the bottom of a pan?
This is an example of conduction, where heat is transferred through direct contact between the burner and the pan. The burner heats the bottom of the pan, which in turn heats the food inside.
Why water in pond feels warmer at its surface but cooler from below in summer?
During summer, the sun heats the surface of the pond more quickly than the deeper layers due to direct sunlight exposure. This results in the surface water feeling warmer. Conversely, the deeper layers of the pond remain cooler as they are not in direct contact with the sun's heat, creating a temperature difference between the surface and the bottom.

Why is temperature high in day than at night?
This is simply due to there being more sunlight in the daytime. The sunlight heats up the land and the air and also passes heat energy into our bodies. The temperature increases when there is more direct sunlight which is why it is hottest at 12:00 (midday).
Does cheese mold faster in the dark or sunlight?
Cheese molds faster in sunlight, if that heats it.
How does sunlight melt snow?
it heats it up and it makes it melt
How does the sunlight affect the atmosphere?
It heats it up by about 30 degrees C.
What makes the equator hot?
The equator receives more direct sunlight compared to other parts of the Earth because of its location where the Earth's curvature is widest, resulting in more concentrated solar energy. This concentrated sunlight heats up the surface area near the equator, making it hot. Additionally, the equatorial region has a consistently high angle of incidence of sunlight throughout the year, leading to warmer temperatures.
Is sunshine warming the sidewalk a chemical change?
No. The sidewalk is still a sidewalk. All of the same molecules are still there in the same arrangement.
How does the sun's energy change as it heats the earth and the atmosphere causing the Greenhouse effect?
By feeling the concrete on the road or sidewalk and feel how hot it is on the beach sand.
How does sunlight heat the air?
Sunlight heats the air by first warming the Earth's surface. The warm ground then heats the air directly above it through conduction. This warm air rises, creating pockets of warmer air that ultimately heat up the surrounding atmosphere.
What transfer of heat is a burner on a stove heats the bottom of a pan?
This is an example of conduction, where heat is transferred through direct contact between the burner and the pan. The burner heats the bottom of the pan, which in turn heats the food inside.
