Science Unit 5 Lesson 7 Flashcards
What is the definition of urban?
Having to do with a town or city
What are green spaces?
Green spaces refers to land that is partly or completely covered with grass, trees, shrubs, or other vegetation.
What are some examples of urban (green) spaces?
- parks
- sport fields
- woods
- community gardens
- green roofs
- natural wetlands
What are the 3 main benfits of green spaces?
- environmental
- economic
- health
How do green spaces help at atmosphere and quality of air?
Environmental
Green spaces help to reduce both noise and air pollution.The trees and plants clean the air and produce oxygen. They help slow global warming by reducing the amount of greenhouse gases that are present in a city
How do green spaces help animals and soil?
Environmental
Green spaces prevent soil erosion and provide a habitat for wildlife.
How do green spaces affect temperature?
Environmental
They moderate the temperatures in a city by having a cooling effect on the urban heat island.
What are some economic benefits of green spaces?
They increase the property values of buildings and homes in their vicinity.
How do green spaces lower energy costs for neighboring buildings?
(Economical)
Because green spaces have a cooling effect, they can help to reduce the energy costs for neighboring buildings.
How do green spaces lower the cost of storm water management?
(Economical)
They absorb rainwater and lower the costs of stormwater management.
How can green spaces increase health in a community?
They provide locations for exercise, relaxation, and social interaction. Community gardens provide healthy foods while increasing physical activity. Green spaces have been shown to reduce stress levels and depression for some people.
What are examples of a combination of the 3 main categories?
A green space can provide benefits in more than one category at the same time. For example, a park might make commuting to work by bicycle more attractive, thereby promoting physical activity for better health and reducing the economic costs of driving a car. A rooftop garden can provide a habitat for insects while increasing the sense of well-being for those who work the garden. An apartment near an urban wood will have lower cooling costs and improved air quality.
Why is creating a green space sometimes difficult?
the greatest challenge in creating urban green space is simply the lack of space. With most land already covered with buildings or pavement, proponents of green space must consider how to renovate buildings to add green roofs or walls. Since older buildings were not designed to bear the weight of green roof or wall materials and do not have adequate drainage systems built in, significant planning, money, and effort are required to successfully complete a renovation.
Sometimes green spaces are created by modifying native habitats give me an example?
Sometimes green spaces are created by modifying or replacing native habitats. For example, a golf course may be constructed on the site of former prairie grasslands. While both can be considered green spaces, the golf course does not have the biodiversity of the grasslands.
What is the main concern with park trials in cities?
Park trails typically require maintenance in the form of patching asphalt or adding gravel. In northern climates, they may require plowing in the winter. If safety is a concern, additional police officers may be required to patrol the trails.
