What causes days to be warmer on one part of Earth than on another?
• the angle at which the sun strikes Earth
• the rotation of Earth
• the speed of Earth in its orbit
• the number of cars on the road
The angle at which the sun strikes Earth.
The main factor causing days to be warmer on one part of Earth than on another is the angle at which the sun strikes Earth. The angle at which sunlight hits the Earth's surface affects how concentrated the solar energy is. When the sun is directly overhead (at a 90-degree angle), the sunlight appears more concentrated and the area receives more energy per unit area. This leads to higher temperatures.
The rotation of Earth also plays a role, as it causes the sun to be at different angles at different times of the day. This rotation creates variations in the amount of sunlight received in different regions, leading to differences in temperatures throughout the day.
The speed of Earth in its orbit mainly affects the seasons rather than daily temperature variations. It causes the Earth to be closer to the sun during some parts of the year and farther away during others.
The number of cars on the road does not directly impact the temperature variations on Earth. However, human activities, including the burning of fossil fuels in vehicles, contribute to the emission of greenhouse gases, which can contribute to global warming and climatic changes over the long term.
the angle at which the sun strikes Earth
The main factor that causes days to be warmer on one part of Earth than on another is the angle at which the sun strikes Earth. This concept is known as solar angle, solar elevation, or solar zenith angle.
To understand this, you need to know that the Earth is a sphere, and as it orbits around the sun, it is tilted on its axis by about 23.5 degrees. Because of this tilt, different parts of Earth receive varying amounts of solar energy throughout the year.
When the sun's rays hit the Earth at a more direct angle, the energy is concentrated over a smaller area, resulting in increased heating. In contrast, when the sun's rays hit Earth at a more indirect angle, the energy is spread out over a larger area, leading to less heating.
Additionally, the rotation of Earth plays a role in determining the duration of daylight. As Earth rotates, different parts of the planet experience sunlight or darkness at different times. This variation in daylight hours affects the overall temperature and contributes to the differences in temperatures between regions.
On the other hand, the speed of Earth in its orbit and the number of cars on the road have negligible effects on the temperature differences between different parts of the Earth.
In conclusion, the primary cause of warmer days on one part of Earth compared to another is the angle at which the sun strikes Earth, with the rotation of Earth also playing a role.
