Urban Heat Islands Effect Guided Viewing
1: What is the difference between regional climate and microclimate?
Regional climate describes the general climatic conditions, and the microclimate is the climate of a small area.
2: Why is vegetation important in climate?
Vegetation is important in climate because plants respond to their minor variations.
3: What are impervious surfaces? How can impervious surface affect local climates?
Impervious surfaces is a hard surface area that either prevents or retards the entry of water into the soil.
4: What is an urban environment?
An urban environment is a city or land occupied by buildings.
5: What is a suburban environment?
A suburban environment are areas on the outskirts of cities.
6: What is a rural environment?
A rural environment is a large amount of land with low population.
7: What is an urban heat island? Explain.
An urban heat island is a developing urban area that causes regions to become warmer.
8: Why do we care about urban heat islands? What do they do to urban environments?
We care about urban heat islands because heat islands affect communities by increasing summertime peak energy demand.
9: What can be done about the urban heat island effect?
We can plant more trees and try to prevent urban sprawl.
10: What are green roofs and what are their advantages?
Green roofs are buildings that are partially covered with vegetation.
11: What is a cool pavement?
A cool pavement is chosen materials chosen to reduce pavement temperatures.
12: What is a pervious pavement? What is the advantage?
Pervious pavements are made of concrete. Their advantage is that they allow air and water to pass through.
FRQ
A: Describe how the temperature of urban areas like Atlanta, Philadelphia, and Chicago differs
from that of surrounding rural areas.
B: Identify and describe TWO differences between urban and surrounding rural areas that contribute to the temperature differences between them.
C: Urban areas typically have levels of air pollution that are significantly higher than those fund in surrounding rural areas. Identify a characteristic of the urban microclimate that lead to higher levels of air pollution and describe how that characteristic contributes to this increase
D: Identify and describe TWO actions that local governments in urban areas could take to reduce air pollution.
A.Temperature of urban areas like Atlanta, Philadelphia, and Chicago differ from that of surrounding rural areas because they have more buildings, structures, and population. They don't have that much vegetation, which is necessary for cleaner and fresher air. Due to all of that of above, temperature is higher and hotter because all the heat gets trapped in there. Temperature in urban areas tend to be higher than in suburban area.
B. Two differences between urban and surrounding rural areas that contribute to the temperature differences between them are population and buildings. Population has a big effect because they increase urban sprawl which contribute to rising temperatures because of their accomplishments. Also, buildings have a big effect too, because those structures trap the heat in the city. Air is not that fresh, and temperature is usually higher, while in rural areas, temperature tends to be quite freshe
C.Urban areas typically have levels of air pollution that are significantly higher than those found in surrounding rural areas because air pollution gets trapped in the city, plus there aren't as much trees in urban areas compared to rural areas. Trees have a big impact on air quality. A characteristic of the urban microclimate that leads to higher levels of air pollution heat coming out of cars, there are more cars in urban areas, so cars also affect the levels of air pollution.
D.Two actions that local governments in urban areas could take to reduce air pollution is to reduce the number of cars, and increase use of bikes, and to create more green rooftops. More vegetation would help air quality and temperatures in cities. We need to plant more, and drive less.
