Why do you think we see the Sun moves across the sky?

From Earth, the Sun looks like it moves across the sky in the daytime and appears to disappear at night. This is because the Earth is spinning towards the east. The Earth spins about its axis, an imaginary line that runs through the middle of the Earth between the North and South poles.

How does the phenomenon atmospheric refraction play a role in the visibility of the Sun from the Earth?

Due to the atmospheric refraction, we can see the sun 2 minutes before and after actual sunrise and sunset. This results in making the sun appear slightly raised above the horizon and hence the sun is visible 2 minutes before and after actual sunrise and sunset.

What is the relationship of the seasons with the position of the Sun in the sky?

As Earth orbits our Sun, the position of its axis relative to the Sun changes. This results in a change in the observed height of our Sun above the horizon. For any given location on Earth, our Sun is observed to trace a higher path above the horizon in the summer, and a lower path in the winter.

What causes sunrise and sunset?

But it appears to rise and set because of the Earth’s rotation on its axis. It makes one complete turn every 24 hours. As the Earth rotates toward the east, it looks like the sun is moving west. As the Earth rotates, different locations on Earth pass through the sun’s light.

Why does the sunset in different places?

Instead of a perfectly-circular orbit, Earth’s orbit around the Sun is slightly elliptical. The combination of Earth’s elliptical orbit and the tilt of its axis results in the Sun taking different paths across the sky at slightly different speeds each day. This gives us different sunrise and sunset times each day.

Why does the sunset in different places throughout the year?

How is the position of the Sun at noon different in the summer than in the winter?

On the summer solstice, the Earth’s north pole is tipped toward the Sun. In the northern hemisphere, this means the Sun gets high in the sky at noon. But in the winter, when the Earth is on the other side of its orbit, the Earth’s north pole is tipped away from the Sun, so at noon the Sun doesn’t get as high.

How does atmospheric affect sunrise and sunset?

Sunrise and sunset are two instants when the upper edge of the sun appears and disappears over the horizon respectively which is the result of Earth’s rotation. This results, when sunlight passes through the atmosphere there will be successive refraction occurs and this results in a bend of sunlight towards the ground.

Why do season change in the Philippines?

Due to high temperature and the surrounding bodies of water, the Philippines has a high relative humidity. … Using temperature and rainfall as bases, the climate of the country can be divided into two major seasons: (1) the rainy season, from June to November; and (2) the dry season, from December to May.

Why does the sun appear larger at sunset?

During sunrise/sunset we are seeing the sun at an angle that passes through the greatest amount of atmospheric gasses (i.e. more “glass”) and therefore looks larger than when the sun is passing directly above us at noon (i.e. less “glass”).

Why are there no stars in the background of space photos?

But, pictures of celestial bodies taken from space by astronauts aboard satellites do not have any stars in the background because stars are very, very far away. Therefore, they are incredibly dim in contrast to other natural or man-made objects present in the foreground of the captured photographs.

What can photos of the Earth tell us about it?

Photographs and other images of the Earth taken from the air and from space show a great deal about the planet’s landforms, vegetation, and resources. Aerial and satellite images, known as remotely sensed images, permit accurate mapping of land cover and make landscape features understandable on regional, continental, and even global scales.

Why do I need to change the exposure setting during sunset photography?

Sunsets are a lot more than that! Shooting only these few minutes can prevent you from getting some pretty amazing and unique sunset shots. Sunsets are continuous light and color-changing events. Applying an exposure setting and leaving it without changing may result in overexposed or underexposed photos.

Why do my sunset photos look bad?

(In this photo the focus on the sun, the camera underexposes the scene) It’s easy to take a bad sunset photo and want to adjust it in a photo editing software to try to fix the exposure and other elements in the image. This can result in unnatural looking photographs that look exaggerated and over edited.
