Answer:
Ice cores can tell scientists about temperature, precipitation, atmospheric composition, volcanic activity, and even wind patterns.
The thickness of each layer allows scientists to determine how much snow fell in the area during a particular year.
Answer:
North America will be wetter in winter, but drier in summer.
Explanation:
What do computer models predict about how precipitation patterns will change in North America for the period 2090-2099, relative to the years 1980-1999? North America will be wetter in winter, but drier in summer.

A granite can be transformed from an igneous rock to a sedimentary rock and then to a metamorphic rock or the sedimentary rock can be transformed back into granite again by metamorphism. First of all, a granite often occurs in mountains and is susceptible to weathering and erosion.. Weathering such as argillic weathering can help break t he rock down to its constituent minerals which are mostly quartz, orthoclase feldspar and biotite mica. This then gets washed down into the rivers and thence to the coast and gets deposited in a marine environment as part of a delta or alluvial fan, in the form of sand, silt, clay and gravel. As this sediment becomes compacted, it turns into rocks like sandstone, siltstone etc. With deeper burial and the addition of heat and pressure these rocks get converted into such metamorphic rocks as quartzites, slates and phyllites, etc. I have seen a meta sandstone grade into a granite in the Canadian Shield so granite can then form from metamorphic processes as well as igneous processes.
The Pacific Ocean is. Its area is about 63.8 million square miles.
That's about 46 percent of all the water area on Earth, and about
one third of the total area of the whole Earth ... land OR water.
