Yes. The length of a shadow is determined by the altitude of the Sun. Therefore shadows shorten then lengthen as each day progresses and, between days, shorten and lengthen as summer comes and passes.
Shadows change throughout the day due to the movement of the sun across the sky. As the sun rises and sets, the angle at which light hits objects changes, causing shadows to lengthen and shorten. The position of the sun also affects the direction and shape of shadows.
Your question isn't very clear but what this describes is the sun rising over the hills and as it does, so the shadows cast by the hills shorten or get driven back.
The altitude of the sun, or its angle in the sky, directly influences the length of shadows. When the sun is low on the horizon, its rays strike objects at a shallow angle, resulting in longer shadows. Conversely, when the sun is high in the sky, the rays hit objects more directly, producing shorter shadows. Thus, as the sun moves throughout the day, the altitude changes, causing the shadows to lengthen or shorten accordingly.
The length of your shadow at 6 am depends on the time of year and your geographic location. Generally, when the sun is low on the horizon in the morning, shadows are longer. As the sun rises, shadows shorten throughout the morning. For a precise measurement, you'd need to consider the sun's position based on the date and your latitude.
Shadows change length and position on Earth primarily due to the movement of the Sun across the sky as the Earth rotates on its axis. As the Sun rises and sets, the angle of sunlight striking objects changes, causing shadows to elongate or shorten throughout the day. Additionally, the tilt of the Earth's axis affects the position of the Sun in different seasons, further influencing shadow characteristics.
