Answer:
Between 2000 and 2012, the Aral Sea has experienced less water income, increased salinity, significant loss of water, the formation of separate parts, and huge loss of biodiversity.
Explanation:
The Aral Sea, once one of the largest in the world, has experienced a tragic story since 2000. Once a great and vibrant lake, it came on the verge of drying out and dissapearing from the map. The reasons for this have been the smaller water income, loss of water, increased salinity, formation of smaller separated lakes, and loss of biodiversity.
Because of agriculture, namely, cotton farming, the water supply to the lake has been significantly lowered, leading to larger evaporation than water income. The lake started to lose its water rapidly, and by becoming shallower its temperature rose, so the evaporation became even larger, the salinity increased, and from one large lake, few smaller ones have formed because a large portion of it dried out. Because of all of the aforementioned things the biodiversity suffered badly.
The western and eastern sierra nevada have substantially different species of plants and animals, because the east lies in the rain shadow of the crest. the plants and animals in the east are thus adapted to much drier conditions.

Answer:
The answer is B
Explanation:
Tree rings form because during each growth season new water and food conducting cells (tracheids) are added around the perimeter of the tree trunk. Cells in the spring growth tend to be larger with thinner walls than the previous set of cells produced at the end of the previous summer. Over the course of the growing season, successive rings of cells become smaller with increasingly thick walls. In winter, growth ceases and no new cells are laid down. Then when the new growing season begins, thin-walled large cells form again producing a clear line between the old wood and the new wood because of the difference in texture.
Tree rings provide a record of past climate because their width is determined by tree growth rate, which in turn is determined by environmental conditions. Since one ring is produced every year (usually) the ages of the climatic events can be worked out very precisely by counting back. Records from young trees, old trees, house and ship timbers and fossil trees can be tied together by identifying sections with the same sequence of climatic event, the records overlap in time where the climatic patterns they record match up.
