How do chemicals affect the climate?
Without chemicals there would BE no climate.
What would a framed signed and numbered print by AB Frost be worth?
Roughly £150
How would California be different if there were no California current?
The climate would be warmer. :)
What is the value of a Turner Wall Accessory of an A B Frost golf print?
The exact value of a Turner Wall Accessory of an A B Frost golf print would actually depend on a couple different things. Some of these things would include the age and condition of the print.
What conditions would be necessary for an earthquake and volcanic eruptions to occur outside these zones?
unreliable
Where would ice wedging occur in Pensacola Florida?
it would occur in the north of pensacola
Would frost wedging be more likely in Butte Montana or Thule Greenland?
== Frost wedging occurs during freeze-thaw cycles. Because Thule is so cold, it would not experience the freeze-thaw cycles in numbers that Butte, Montana would.
Where on earth would physical weathering from temperature changes be least common and why?
In cold regions because ice wedging also known as frost wedging physically breaks apart rocks.Ice wedging causes cracks in rock to expand as water seeps in and freezes. So colder regions is where it is least common for physical weathering to occur from temperature changes.
Would frost wedging me more effective in cool high desert areas or where the subsoil is permanently frozen?
It is the feeze/thaw cycle that makes frost wedging really effective as an erosive force. Desert areas that are warm during the day and freezing at night experience more wedging than permafrost areas.
In whch area would weathering by frost wedging probably be most effective?
in moist, mid-latitude climates
Would ice wedging happen if water did not expand as it froze?
No, it would not. Wedging cannot occur if the solid form (ice) didn't occupy a greater volume than the liquid form.
Examples of Mechanical weathering?
Frost wedging & exfoliation are common terms associated with mechanical weathering.
Does a cold climate help mechanical weathering?
No. mechanical weathering is the breaking and separating of rock or other materials. In order for mechanical weathering to occur you need water or some kind of mass movement. the only erosional agent which works with mechanical weathering are creep and solifluction, but mechanical weathering itself cannot happen because if it is too cold the frost wedging cannot happen becasue the water would freeze in contact and would not expand
In which climate would the chemical weathering of limestone occur most rapidly?
Warm and humid
Would ice wedging be an important cause of mechanical weathering near earth equator?
Ice-wedging could never occur at the equator, for two very simple reasons. The first is that it is almost always far too hot at the equator for ice to form, due to the high insolation. The second is that even at altitudes high enough for frost to form daily at the equator (roughly above 3,000 metres or 9,800 feet) precipitation, despite declining with altitude due to the low effectiveness of convective rainfall in cool temperatures, is always adequate to prevent deep nightly freezing. At the equator, owing to the high precipitation, the snow line is no higher than the altitude of a mean annual temperature of 0˚C or 32˚F (around 4,600 metres) and ice-wedging obviously cannot occur in areas covered by glaciers.It might be noted that in arid tropical mountain (confined today to the Desert Andes) ice-wedging can occur as close to the equator as 18˚S, since the snow line is around 1,500 metres or 4,920 feet higher than it is at the equator and continuous permafrost exists on mountain tops.
What mechanical weathering process results in enlargement of fractures and extension of them deeper into large boulders and bedrock?
Frost wedging would be the primary process. Other mechanical weathering processes resulting in the extension of rock fracturing could include pressure release from uplift, and plant root growth.
What breaks down rocks and other materials at earth's surfaces?
Weathering is the breaking down of rock by physical or chemical means. Examples would be frost wedging, dissolution by acidic rainfall, and abrasion.
