Anything that is rounded has a convex shape. A convex lens is used to bend light inward. When people cannot easily see things that are close, convex lenses help to bend the light so they can see more clearly.Some mirrors on the outside of cars and trucks are convex mirrors. If a mirror on the outside of a car or truck is convex, you will see a message at the bottom of the mirror that reads "Objects in the mirror are closer than they appear." When a mirror is convex, objects appear further away because of the way the convex shape of the mirror bends light.Perhaps you have even seen large convex mirrors in parking garages and inside of elevators. These mirrors allow you to see all around so that you know that it is safe to enter.???? ???? ????? ??????. ?? ??? ????? ?? ??? ????. ?????? ??????? ??????? ???? ????? ??????. ????? ?? ??? ????? ????? ?????? ??????? ??? ??????? ??????? ????? ?? ??? ????? ???? ?????? ?? ??????? ????? ????.??? ??????? ???? ???????? ????????? ??? ????? ?????. ??? ???? ?????? ??? ???? ??????? ?? ??????? ?????? ???? ??? ??? ????? ???? ?????? ?????

It is important to make sure that a ladder is stable before you climb up it, otherwise it may tip over.Things in nature can also be stable or unstable. After a long winter with snow and rain, rocks and dirt on a hillside or mountain can become unstable and can break loose. Trees growing on hillsides and mountains help to make the rocks and dirt more stable.The word stable is also often used to describe the populations of plant and animal species.

Plants and animals take advantage of the food and shelter in their surroundings, as well as the weather and climate. For example, many people live near oceans to take advantage of the pleasant climate and abundant sources of food near the ocean. Many plants grow best where they can take advantage of sunshine and water. That is why there are many plants in tropical areas where it is warm and it rains a lot.People often consider advantages and disadvantages when they decide where to live. This population map of Massachusetts from the year 2000 shows that most people have chosen to live where they have access to the major water ports and distribution hubs on the east coast of that state. Water ports are important for transportation of goods and services both in and out of the state. That means jobs for many people. ??????? ?? ???? ?????? ?????? ?? ????? ?????. ???????? ?????????? ?????? ?? ?????? ??????? ?? ??????? ????? ??? ????? ???????. ??? ???? ??????? ???? ?? ??????? ???????? ????? ???????? ???????? ?? ????? ??????? ????? ????? ?????? ????? ??????. ???? ?? ???????? ???? ???? ????? ?????? ?? ????? ??????. ????? ???? ?????? ?? ???????? ?? ??????? ?????????? ??? ????? ?????? ??????.????? ??????? ????????? ?????? ??????? ???????? ????? ?????? ??? ??????. ???? ??????? ???????? ?????? ?????????? ??? ????? 2000 ? ???? ?? ???? ??????? ??????? ????? ?? ?????? ???? ???????? ?? ?????? ??????? ??????? ?????? ??????? ?? ?????? ??????? ?? ??? ???????. ??????? ??????? ???? ???? ??????? ???????? ?? ???? ???????. ???? ???? ????? ????? ?? ???????.

The air does not have to be blowing to produce air resistance.Air resistance is very important in some sports. Athletes may decide what to wear based on air resistance. In sports where speed is important, athletes wear clothes that produce very little air resistance. Runners and bikers sometimes even shave their legs and heads so that their hair will not slow them down. With less hair on their body, there is less air resistance.For some activities, people need to find ways to increase air resistance. People who sky dive or hang glide use large pieces of material to create greater air resistance so that they can float to the ground safely. ?????? ?????? ?? ??? ?????? ???? ????? ?? ??? ????? ?? ??????. ?????? ??? ????? ????? ?????? ????? ?????? ????.?????? ?????? ???? ???? ???? ????????. ?????????? ?????? ???? ?????? ???????? ??? ?????? ??????. ??? ???????? ???? ???? ?????? ???? ???? ??? ????????? ?????? ????? ???? ?????? ???? ????? ????. ???????? ????????? ??????? ?????? ??????? ??????? ????? ??? ????? ?? ???????. ???? ??? ?? ?????? ????? ???? ?????? ???? ???.???? ????????? ????? ??????? ?????? ????? ???? ???? ?????? ??????. ??????? ????? ?????? ?? ?????? ?? ??????? ??????? ???????? ???????? ????? ????? ??????? ?????? ???? ???? ????? ?????? ??????? ??? ????? ?????.
