Causes
What is the primary cause of Tsunami's
Earthquakes
How do Earthquakes affect settlement
Change building codes, cause tsunamis, Reduce populations along fault lines
A change in a regions weather patterns over time
What is the area around the pacific ocean covered in volcano's called?
Ring of fire
Name 1 type of landslide
Falls, Topple, Slides, Spread and flows
What is the cause of drought
Change in precipitation patterns or climate change
How does flooding affect settlement
Creation of man-made barriers, flood plains (fertile areas), decrease of settlement near areas that flood
Define Desertification
the process by which fertile land becomes desert, typically as a result of drought, deforestation, or inappropriate agriculture.
How are earthquakes measured
Richter scale or seismograph
Positive effect of warmer temperatures?
Longer growing seasons for farmers, Transportation in colder climates and Increase settlement in northern cold areas
What causes rising sea levels
How do volcanos affect settlement
Define settlement
a place, typically one that has hitherto been uninhabited, where people establish a community.
Explain the difference between climate change and global warming
Climate change is a change in weather patterns over time and global warming is simply increase in global temperatures
What is land reclamation and give an example?
Creating artificial land or reclaiming land lost to the sea. Examples include Netherlands and Dubai
What causes coastal erosion?
hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural (any of these)
Causes migration, loss of jobs, dry up farms and fields, very difficult to sustain any life without water
Define weather
the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.
Besides earthquakes, what else can cause tsunami's?
Landslides, volcano and near-earth objects (comets or asteroids)
Explain active vs dormant volcanoes vs extinct volcano's
Active volcanoes have erupted recently and are likely to erupt again/
Dormant volcanoes have not erupted recently but may erupt in future
Extinct volcanoes are not expected to erupt again
What causes climate change?
Greenhouse gas emissions (pollution)
Affect of landslides on settlement
Avoid building near cliffs or on side of mountains, settlements prefer the rocky and solid ground to muddy and wet areas in mountainous areas.
Define physical process
What causes precipitation
When a mass of warm and moist air hits a mass of cold air
