Weathering of fractured granite and massive sandstone?
cut
Spheroidal weathering is the result of chemical weathering of systematically jointed, massive rocks, including granite, dolerite, basalt and sedimentary rocks such as silicified sandstone. It occurs as the result of the chemical alteration of such rocks along intersecting joints.
23
How does co2 cause sea level rise?
“ocean inertia”: As the world warms due to greenhouse gases — carbon dioxide included — waters heat up and expand, causing sea levels to rise
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

Canada balsam is also used as a food additive, in manufacturing, and in dentistry. so called Canada turpentine or balsam of fir, is the oleoresin of the balsam fir tree (Abies balsamea) of boreal North America. The resin, dissolved in essential oils, is a viscous, sticky, colourless or yellowish liquid that turns to a transparent yellowish mass when the essential oils have been allowed to evaporate.
Canada balsam is amorphous when dried. It has poor thermal and solvent resistance.[1]

What is the difference between a chinook and a foehn?
The wind off of the Rocky Mountains in North America is a foehn wind that is called a Chinook wind. A foehn wind is a warm, dry wind that descends on the eastern slopes of most mountains. A warm wind like this can bring relief from cold winter weather.
Fohn is a cold and dry wind flowing in tundra regions which decreases the temperature of these areas to below freezing point. 2. Chinook is a warm dry wind which blow along the eastern slope of the Rocky mountains and is also known as snow eater.

Sinkholes are common where the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by groundwater circulating through them. As the rock dissolves, spaces and caverns develop underground.
