Pumping sand onto a beach from offshore bars is one way:
to perform beach nourishment
_____________ are those in which flaming combustion is carried through the canopies of trees
includes global warming due to increased greenhouse gases from human activities
With a warming climate, sea-level will increase due to the melting of continental ice sheets on land and:
thermal expansion of sea water
A wave will "feel bottom", move slower on the bottom than the top, become steeper and eventually break when:
water depth is less than 1/2 wavelengths
What is the correct relationship between faults and earthquakes?
Movement along faults causes earthquakes
An active sun releasing more energy has more:
A backfire does NOT:
push in the opposite direction of an advancing fire
The silica content in a magma controls:
During winter, sand from the berm on a beach may be moved:
By storm waves to offshore bars
True or false: A landfalling hurricane can cause storm surge, flash flooding, downstream flooding, and mass wasting
TRUE, in addition to the surge, the rains may be heavy enough to cause additional problems inland
_________ are periodic changes in Earth's orbit and the tilt and direction of Earth's axis.
Which of the following is not a reason why more extreme weather could occur in a warming climate?
Increased carbon dioxide provides more chemical energy to the atmosphere, which creates more instability, heating and stronger storms
When caught in a rip current, one should:
swim parallel to the beach until you are out of the current
Delaware and Chesapeake Bays are examples of:
Factors that helped contribute to the deadly landslides at La Conceit in 1995 and 2005 do not include:
The lowest Arctic sea ice summer minimum occurred in:
_________ are a daily change in sea level due to gravitational pull of sun and moon
Wildfires move faster:
If you encounter a flooded roadway while driving you should:
stop and turn around, do not try wading across
The ______________ is the global circulation and exchange of warm surface and cold deep water in the earth's oceans
Global conveyer or thermohaline cycle
Which of the following does not affect the size of ocean waves?
Length of time the wind blows
Which of the following statements about Hurricane Katrina is true?
Not only was the predicted path accurate, the effects were as expected
At current rates of CO2 increase, the most likely scenario is:
4-6 C increase in global average temperature by 2100
Which of the following statements is true?
Average global temperatures are increasing, but there will be still cold days and snow. However, there will be less extreme cold days and more extreme hot days
Beaches absorb the energy of a wave as it crashes onto the beach. Larger waves have more energy than smaller waves because:
Wave energy is proportional to the wave height squared.
When more Arctic Sea Ice melts in the summer, more ocean is exposed. The open ocean is darker than the ice and absorbs rather than reflects sunlight. This leads to further warming and more melting. This situation is an example of:
Linear structures placed perpendicular to the shore in groups are known as:
The three sides of the fire triangle are:
fuel, oxygen, and heat
Which of the following is not a "greenhouse" gas:
After a large volcanic eruption, ash and SO2 injected high into the atmosphere...
....causes global temperatures to decrease because more incoming solar radiation is reflected back into space
The input, storage and output of sand or gravel from a beach is the:
What is released when water vapor condenses?
The 2010 Haiti Quake was M7.0 while the 2011 Tohoku, Japan Quake was m9.1, yet the Haitian quake was much deadlier. Why?
The epicenter of the Haitian quake was close to a densely populated city with poorly constructed concrete buildings
The amount of reflection a substance has is known as:
Why are the fire triangle and tetrahedron useful?
answer: all of the above
- They show the components needed to have a fire
- they show that by removing any component you can destroy the shape or in other words, put out the fire
- They are easy to visualize and remember
______________ refers to changes in air pressure and sea surface temperatures in the Pacific that can lead to warmer than average sea water off Ecuador and Peru and shifts in global weather patterns
The expected weather and weather patterns based on past averages and patterns is:
Tree rings, fossils, and ice cores are some of the sources of data for:
"Hard" solutions to beach erosion such as seawalls and jetties may:
actually accelerate erosion in some areas.
As the oceans absorb more CO2, they'll become more acidic. This can:
damage corals and disrupt ecosystems
As sea levels rise, shorelines
upwards and landwards
A natural process that is a threat to human life or property is a:
A narrow, steep sided, heavily wooded mountain valley containing a small rocky stream:
What type of hazard could occur in this valley during a period of intense rainfall?
A + C
- mass wasting (landslides)
- A flash flood
What type of hazard could occur in this valley during an earthquake?
mass wasting (landslides)
What hazard could increase in this area due to climate changes?
More frequent wildfires if there are extended droughts
A low lying, sandy barrier beach in a subduction zone location:
What type of hazard could occur on this beach during a strong coastal storm?
What type of hazard could occur on this beach during an earthquake?
A + B
- a tsunami
What hazard could increase in this area due to climate change?
D - all the above
- more frequent storm and storm surge
- more frequent storms and increased beach erosion
- sea-level rise
Incoming solar radiation reaches the earth as visible (mostly yellow) light. After being absorbed by the Earth's surface (heating it), this energy is radiated by the Earth as ____________
The ____________ in the U.S High Plains during the 1930s was due to a combination of extended drought and agricultural practices not suitable for the region.
Refracted waves have some of their energy directed parallel to shore, which produces a current along the shore known as ______________
Heavy precipitation and rapid runoff into a small drainage basin can result in a ___________
A __________ is when a fire becomes large enough to create powerful inflowing winds and grows in intensity
