Geography

Questions referring to chapter 2 geography.

QuestionAnswer
How does climate change affect settlements? Warmer temperatures, changing precipitation patterns, more frequent and extreme storms and rising sea levels.
What did you learn about warmer temperatures? Earths average temperature is increasing. Warmer temperatures may affect settlement patterns, making some areas better and others worse to live in.
What did you learn about changing precipitation patterns? The world will likely become wetter, due to higher average temperatures. Some areas will be much wetter, causing more floods and landslides. Some areas will be much drier, causing desertification and drought.
What did you learn about more frequent and extreme storms? There will be more hurricanes, cyclones, typhoons and tornadoes. Storms will be stronger than in the past and cause more damage to settlements and threaten lives.
What did you learn about rising sea levels? Sea levels are rising twice as fast as in the past due to warming oceans and melting ocean ice and glaciers.
What are the physical processes that affect settlements? Volcanos, earthquakes and tsunamis, desertification and landslides.
What are the potential threats of volcanoes? Eruptions release lava, gas, and ash, damaging settlements and causing injury or death.
What are the potential threats of earthquakes or tsunamis? Destruction of property and loss of life and tsunamis can wash away costal settlements.
What are the potential threats of desertification? Loss of arable land, dust storms, damage equipment, buildings, and human health.
What are the potential threats of landslides? Destruction of settlements and loss of life.
What are the reasons for settling around volcanos? Despite threats. Areas around volcanos may be good for mining and having fertile soils, volcanos provide access to geothermal energy, and volcanos can cause tourism.
What are the reasons for settling around earthquakes or tsunamis? Despite threats. Earthquakes often occur along tectonic plate boundaries, which tend to be on coasts, but coasts provide access to shipping, fishing and natural beauty.
What are the reasons for settling around desertification? Despite threats. Land may have once been fertile.
What are the reasons for settling around landslides? Despite threats. Land at the top of a rise often has spectacular views, land at the base of a rise often provide protection from elements, and other land is not available.
For a volcano, what are the steps to lessen threats or respond to an event? Provide early warning signs and develop an evacuation plan.
For an earthquake or tsunami, what are the steps to lessen threats or respond to an event? Conduct earthquake drills, prepare shelters, emergency kits and evacuation plans and build buildings that limit the damage from earthquakes.
For desertification, what are the steps to lessen threats or respond to an event? Plant shelter belts to prevent erosion and irrigate to provide moisture to the soil.
For a landslide, what are the steps to lessen threats or respond to an event? Conduct barriers against slides, reinforce embankments and plant trees and grasses to strengthen embankments.
