Hurricanes
warm air provides this for hurricane formation
fuel/energy to grow
Which material is most permeable?
A. Clay
B. Sand
C. Concrete
D. Metal
Sand
This is an impervious surface
A surface that allows water to pass through
Pervious surfaces help reduce what natural disaster?
Flooding
A watershed is often described as having this shape
an upside down umbrella
hurricanes are classified into categories based on this variable
wind speed
What property describes how much empty space a material has?
porosity
Name one natural feature students might record during a school campus site inventory.
Trees, soil, slopes, streams, or planted areas.
What planted feature collects rainwater and allows it to soak into the ground?
rain garden
What force causes rainwater to flow downhill toward streams and rivers?
gravity
this variable helps organize and strengthen a hurricane
strong wind speeds
What property describes how easily water moves through the spaces in soil or rock?
permeability
If microclimates exist during a site inventory check, which samples have the higher temperature?
man made structures that are dark in color.
replacing concrete with permeable pavement help reduce flooding because
It allows more water to soak through the surface and into the ground.
can litter or chemicals on a parking lot eventually pollute a river?
yes - Runoff can carry the pollutants into storm drains and streams that flow toward the river.
This condition will most likely weaken a hurricane?
moving over land
Two soil samples have the same volume. One has more pore space than the other. Which soil has greater porosity?
The soil sample with more pore space.
How can planting trees around a school help reduce the urban heat island effect?
Trees provide shade and release water vapor, which helps cool the surrounding area.
A school parking lot sends muddy runoff into a nearby stream. Name one stormwater management practice that could help.
either A bioswale, rain garden, permeable pavement, or another feature that slows, captures, or filters runoff.
This can harm watershed health
point source pollution
low air pressure effects hurricane development in this way
it allows air to rise which makes cold air fill in the space
A school wants to build a rain garden where water can soak into the ground quickly. Should it choose soil with high or low permeability?
High permeability
What type of plants are adapted to the local environment and often support local wildlife?
Native plants
this is how a bioswale works
a bioswale collects and slows runoff,
What geologic feature creates physical barriers to separate watersheds?
ridgelines or moutnains
