Beach Erosion
Sand fences on a beach help protect this, which hold the soil together, create a habitat on a beach, and help reinforce sand dunes.
What is vegetation?
The height difference between high and low tide
What is tidal range?
Waves do this when they hit a wall or other obstruction.
What is reflect?
Most surf-zone fatalities (deaths) are caused by these.
What are rip currents?
This line of defense protects steeper cliffsides or developed coasts. Japan has utilized many of these tall structures to protect various parts of their coastlines.
What are seawalls?
The tides are a bit later each day because the lunar day is this much longer than the Earth day.
What is 50 minutes?
When waves bend to become more parallel with the coast line.
Steep beach slopes will result in which type of wave breaker?
What is surging?
These structures are usually built perpendicular to the shore to help direct water flow through a particular channel. This helps reduce shoaling erosion.
What is a jetty?
These phases of the moon coincide with a more intense tidal range.
What are full and new moon?
Waves spread out after entering a narrow barrier because of this property.
What is diffraction?
During wave shoaling, wave energy has nowhere to go but ____________.
What is up?
Even if we achieve zero carbon emissions by 2100, the sea level is still predicted to rise about how many meters by the year 2300?
About 1 meter
Diurnal refers to one high and one low tide per day, while semidiurnal refers to two high tides and two low tides each day. Some, rare, locations experience both, which is given this term.
What is mixed?
A headland experiences larger waves because of this type of wave interference.
What is constructive?
Two causes of Tsunamis
What are submarine landslides & underwater earthquakes?
The mouth of the Piscataqua River has these erosion protection structures in place right as the river enters the Atlantic Ocean. They run parallel to the shore to help reflect and/or dissipate wave energy.
What are breakwaters?
This river in China is well-known for their tidal bores during the flood current.
With wave reflection, it does not matter which direction the wave approached an obstruction. The angle at which the wave reflects the object it hit will always be ___________.
What is equal to the angle at which it initially hit the obstruction?
The 2004 Tsunami first made landfall on what Island?
What is Sumatra?
