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.
Respiration, volcanoes, burning fossil fuels, and man made excretion.

Well, they need to live in warmer weather since they have short fur.. The ecosystem in which giraffes live is called the savanna and Savannas are found between desserts and tropical rain forests.. Their climate is a mixture of both, <span>wet enough to keep the trees alive, but too dry for woodlands.</span>
The area surrounding big bear lake accurately described by the statements: Cretaceous or Jurassic quartz monozite is found to the west of the lake, Well-dissected alluvial fan deposits are found to the east of the lake, Many faults are found to the north and east of the lake.
Option: A,B &D
Explanation:
According to the gelogical time period Cretaceous and Jurassic period belong to Mesozoic era. Big bear lake was formed during that time. So the mineral quartz, monozite sand found in the west of the lake.
Alluvial fan is formed by the river in its lower course when velocity goes down and all the transported sediments deposited in the foothill zone forms fan shaped land feature known as alluvial fan.Many faults that created by tensional force on the earth's crust found to the north and east of the lake.
