NOAA Tides
1: What are tides?
Tides are regular alternating rise and fall of sea level.
2: What causes tides? Explain in detail (show diagram)
They are caused by the gravitational pull of the moon and sun.
3: Where do tides occur?
Tides occur around the world on the coastlines.
4: Explain- High and low tides (difference)
During a low tide the water is getting pulled away from the shore because the moon is facing a side of the earth and pulling the waterback, but when the earth rotates and the moon isn't facing that side anymore the water comes back in for high tide.
5: Which object exerts the most force on the tidal bulge? Why?
The moon exerts the most force on the tidal bulge, because the sun is farther away from the earth even though it has more mass, which causes the moon to exert more than twice the tidal force.
6: What happens when the sun and moon align? What happens when they are perpendicular to
each other?
When the sun and moon align they produce spring tides. When perpendicular they cause a neap tide.
7: What are some of the other factors that affect tides?
The shape of the coast-line, sea-floor topography, river discharge, wind, and weather conditions.
8: What are the zones of the intertidal zone?
Spray, Upper Inter tidal, Mid Inter tidal, Low inter tidal, Subtidal zone.
9: What are some of the challenges for the critters of the intertidal zone? Explain.
They get exposed and they have to find ways to hide like bundle up in their shell or hide beneath rocks.
10: How do the inter tidal organisms COPE with the harsh environment?
They COPE with the harsh environment with tough leaves that can resist water loss, soft body animals, some scrunch up their bodies with a coding layer of mucus, some burrow under the sand, and some hide behind rocks.
11: What are some of the adaptations that help organisms cope with wave action?
Do: Predicting the Tides
Sea stars have powerful arms to hold on tight, Clams have shells and can hold on to rocks,
What is the global impact of tides? Explain. The global impact of tides, when tide currents bounce off the sea-floor ridges and shells. The turbulence mixes ocean water, redistributing heat and some nutrients, to help regulate the climate.
What are some of the challenges on coastal areas because of tides?
Some of the challenges on coastal areas cause problems for coastal residents, designers of faculties as, ports, bridges, and off shore oil plat-forms.
Explain how electricity can be generated by currents and tidal power.
Electricity can be generated by currents and tidal power by using off-shore turbulence.
