The shadow is cast by the sun.
As the earth rotates on it's axis, the sun appears to move across the sky in an arc.
The height and direction of the sun is constantly changing throughout the day and so the shadow will also change. When the sun is high the shadow is short. When the sun is low, the shadow will be long.
What else can I help you with?
Why does the size of the shadow change in a day?
Because the sun's change in apparent motion across the sky results in a change in the angle of the shadow that is cast.
How does measuring shadows help us determine what time of day it is?
Measuring shadows is useful for determining time of day because the length and direction of a shadow change based on the position of the sun in the sky. By measuring the length and direction of a shadow cast by an object, we can estimate the angle of the sun and roughly determine the time of day. This method is commonly used with tools like sundials.
Why your shadow changes during the day?
The position and length of your shadow change throughout the day due to the angle of the sun in the sky. In the morning and evening when the sun is lower in the sky, your shadow will be longer. At midday when the sun is directly overhead, your shadow will be shorter.
What changes during the day but always points away from the sun?
A shadow is what changes during the day but always points away from the sun. The position of a shadow shifts as the sun moves across the sky, causing the direction of the shadow to also change throughout the day.
What time of the day do you think it is when your shadow is the tallest?
The lower the sun is in the sky, the longer your shadow will appear on the ground before you. Therefore, a sunny dawn or just before sunset is the time of day for long shadows.
