Tides
The daily rise and fall of ocean water caused mainly by the Moon’s gravity.
What are tides?
The main cause(s) of global sea level rise due to climate change.
What is melting ice and warming water (thermal expansion)?
The process where new ocean crust forms at mid-ocean ridges.
What is seafloor spreading?
The movement of ocean water from one place to another.
What is a current?
Miami has raised many of its streets to prevent this problem.
What is flooding?
When the Sun, Moon, and Earth are lined up, producing the highest high tides and lowest low tides.
What are spring tides?
When ocean water warms, it does this, causing sea levels to rise.
What is expand?
This molten material rises from the mantle to create new crust.
What is magma?
The AMOC is driven by differences in temperature and this.
What is salinity?
These pumps remove excess water from streets during high tides.
What are water pumps?
When the Sun and Moon pull at right angles, causing smaller differences between high and low tide.
What are neap tides?
Melting of this large ice sheet could add freshwater and affect ocean currents like the AMOC.
What is Greenland?
The type of plate boundary found at mid-ocean ridges.
What is a divergent boundary?
Cold, salty water is more ______ and therefore sinks.
What is dense?
Natural systems like mangroves help reduce this during storms.
What is storm surge?
The Moon’s gravity pulls on this part of Earth to create tidal bulges.
What is the ocean water?
Rising seas increase this problem in Miami neighborhoods during storms.
What is flooding?
As new crust forms, older crust moves this direction.
What is away from the ridge?
The Gulf Stream carries this type of water toward Europe.
What is warm water?
Planning buildings farther from the shoreline is an example of this strategy.
What is adaptation?
The tidal bulge on the opposite side of the Earth is created by this force.
What is inertia
A long-term effect of sea level rise on Miami’s coastline.
What is coastal erosion?
Evidence for seafloor spreading includes symmetrical patterns of magnetic stripes in these ocean rocks?
What are lava pillows?
If too much freshwater enters the North Atlantic, the AMOC could do this.
What is slow down or weaken?
Reducing greenhouse gas emissions helps slow this global problem.
What is climate change?
