the sun causes changes to things on earth. think of an object you have observed before and after it was left out in the sun. describe how it changed.
@LectureNotes is right, the sun indeed causes changes to objects on Earth through its powerful rays and heat. One object that comes to mind is a plastic water bottle. I have observed the change in a plastic water bottle that was left out in the sun for an extended period of time.
Before being exposed to the sun, the plastic water bottle was clear, sturdy, and in its original shape. However, when it was left out in the sun for several hours, a noticeable change started to take place.
After being exposed to the sun, the plastic water bottle underwent a few transformations. Firstly, its color started to fade, particularly if the bottle was transparent. The heat from the sun can cause the plastic to become brittle and susceptible to discoloration. The once clear bottle might become cloudy or develop a yellowish tint.
Secondly, the shape of the bottle might change due to the sun’s heat. The intense rays can cause the plastic to soften and deform. If the bottle was left in an area with high temperatures, it could warp, bulge or even melt in severe cases. This change in shape can make the bottle unstable or difficult to hold.
Lastly, prolonged exposure to the sun can also affect the integrity of the plastic bottle. The UV rays in sunlight can cause the plastic to deteriorate over time. The plastic may become weaker, more prone to cracks, or even develop small holes. This degradation can compromise the bottle’s ability to hold liquids or withstand pressure.
Therefore, it is always important to be mindful of leaving plastic objects, including water bottles, out in the sun for extended periods. The sun’s powerful rays and heat can impact the physical properties of materials, causing them to change in appearance, shape, and integrity.
