Why do the islands have moderate temperatures?
because of high specific heat capacity.
What factors contribute to an urban heat island?
Increased precipitation downwind of the city.
What conclusion might you make about summer temperatures in a large city compared with those in a surrounding countryside?
Large cities are often called "heat islands" The large amount of activities and energy expenditure, such as from cars, factories, lighting etc, can cause the temperatures in large cities to be slightly higher than the surrounding countryside. Localised air pollution also has a insulating effect, which also causes the temperature in the city to be slightly higher. See below. http://en.wikipedia.org/wiki/Urban_heat_island (If this was helpful, please recommend me.)
What factors contribute to metamorphism?
Intense Heat and Pressure.
What does heat do to a rock?
At high temperatures, the minerals in a rock can change to other minerals. And, of course, rock can melt.
Why do the islands have moderate temperatures?
because of high specific heat capacity.
What is urban heat islands?
In a city, air temperatures are often as much as 3-4 °C higher than over open country. These higher temperatures are generated by the combustion of fuels in factory, heating, and transport systems, and, more importantly, the release at night of heat which has accumulated during the day in the fabric of the city, for the bricks and concrete of the buildings act as enormous storage heaters. This effect is compounded by air pollution, which reduces night-time terrestrial radiation, and by the low humidity which results from the lack of vegetation. A urban heat island is developed during calm conditions; winds disperse heat.
What is energy that flows from higher temperatures to lower temperatures?
Heat.
Which direction does heat flow from when both temperatures are the same?
When both temperatures are the same, heat does NOT flow between objects.
What are the effects of concrete jungles on rising temperatures?
Concrete jungles, or Urban Heat Islands, as they are known, hold the heat better. Cities, especially cities with few parks and green belts, are usually warmer than the countryside. This, however, does not affect global warming. Globally temperatures are averaged, and the cooler countryside balances out the warmer cities. Scientists measuring the temperature are always careful to make sure urban heat islands do not influence the temperature trends, which are increasing at the same rate in cities and countryside.
What causes heat islands?
Is where the climate is warmer the in surrounding rural areasone factor could be the specific heat capacity of the material of say a city (concrete) or the ocean (water)
Thermal energy that flows from higher temperatures to lower temperatures?
heat
What is it called when heat can go from cooler to warmer temperatures?
"heat" can not go from colder to warmer temperatures. Heat is not an object, it's energy. Temperature is simply a measurement of how much heat an object possess.
When temperatures are too high?
When temperatures are high it causes the environment to heat up.
Does heat move from areas of high temperatures to areas of low temperatures?
Yes
Why would increased levels of greenhouse gases contribute to higher temperatures?
Greenhouse gases trap the heat rising fom the earth. Increased levels of greenhouse gases mean that global warming will get worse.
What factors contribute to an urban heat island?
Increased precipitation downwind of the city.
