Why are autumn trees described as deciduous?
Trees that lose their leaves once a year are called "deciduous." In cooler climates this is usually in Autumn. In some climates plants lose their leaves in the Dry season these are also called deciduous. Losing all the leaves is the important part. Trees that stay green all year round are called "evergreen"
Can we get burnt paper back to its original form?
No it can't, because it would have undergone a chemical change, which is not easily reversible. so it is highly unlikely that it would. In addition, if burnt paper is touched, it would only crumple and turn to ash. Thus, your brilliant answer.
How do you maximize the good effects of physical change?
To stop being dumb and throw my trash in the proper garbage can,plant more trees,,and to avoid burning
Names of trees that do not lose their leaves in winter?
Evergreen, or coniferous.http://www.elmcare.com/trees/types_of_trees.htmTrees can also be divided into deciduous and coniferous categories.Deciduous trees are also known as broadleaf trees because the leaves are generally larger and wider than those of conifers. The larger leaf size means a greater surface area for photosynthesis, but it also mean the leaf is too fragile to withstand winter conditions. Therefore, most deciduous trees drop their leaves in autumn.Coniferous trees keep their leaves throughout the year, shedding only the oldest leaves. Usually these leaves are lower down on the tree and do not receive as much sunlight as newly developed leaves higher up. Some of the best-known members of the conifer family are pines, spruces, firs, and hemlocks. The cones of the conifers are its flowers.The coniferous trees mentioned above do not have leaves. Their foliage is needles. A sample of a tree that does not lose it's leaves in the fall is the Arbutus tree. This tree sheds it's bark which is used to make pharmaceuticals for the medical field.
What about deciduous trees in winter is not true?
Deciduous tress do go into dormancy during winter months. Deciduous trees will start to lose their leaves in autumn. This process is called abscission.

Is cutting of tree a chemical change?
No. Trees' leaves change colors beacuase when winter comes around, they will not have the energy to keep leaves, so they seal off the leaves from the rest of the tree. When the leaves are cut off from the rest of the tree, the chlorophyll in them dies, and turns brown.

Why do tree's leaves change color in fall?
Certain types of trees, known as deciduous trees, have leaves which will not survive the cold of winter, and therefore, the tree withdraws useful minerals from the leaves in the fall, so that those minerals will not be lost when the leaves die and fall off the tree. It is a process of nutritional conservation. The change in the chemical composition of the leaves causes a corresponding change in color.

Is the cutting of trees a physical or chemical change?
The act of cutting the tree is a physical change. However, there are chemical changes that take place as a result of cutting the tree. All plants have an ability to "feel" when they are being damaged and the plant cells around the damaged ones stiffen to attempt to prevent further damage.
