1:What are tides?
Tides are regular alternating rise and fall of sea level which are caused by the gravitational force of the moon and the sun.
2: What causes tides?
Tides are caused by the gravitational force of the moon and the sun as well , however there are reasons of why this happened, for example one of them can be the earth rotation movement.
3: Where do tides occur?
Like I said in the question above tides happened a cause of the gravitational force of our natural satellite "the moon", the sun and the earth rotation. They caused that tides move to a specific location called tidal bulges these two parts are located in the sides of the earth where the moon is more near to and the opposite side is the other tidal bulges.
4: Explain- High and low tides (difference)
We call high tides when these reach a high sea level which actually touches land in some towns , etc. But we also call low tides to those who after the high tides start reaching a huge low sea level or Ebb Current that sometimes may cause something like a drought. So in fact, the difference between high and low tides is the lower and higher range that they reach.
5: Which object exerts the most force on the tidal bulge? Why?
The object that generate the most force in the tidal bulges is our natural satellite the moon. This is because even though moon and sun generate the tidal bulges the distance between these two factors is humongus . Furthermore the moon is near to the earth causing a greater effect than the sun force.

6: What happens when the sun and moon align? What happens when they are perpendicular to each other?
When the sun and the moon align their gravitational forces combined producing very highest and lowest tides called Spring Tides. When the moon and the sun are located in right angles or in perpendicular form which is the same the pull at the sea from different direction and moderate tides , producing which is called Neap Tides.
7: What are some of the other factors that affect tides?
Some of the factors that affect the tides arethe shape of the coast line, seafloor topography , rivers discharge, air , weather conditions.
8: What are the zones of the intertidal zone?
Spray Zone , Upper Interditial Zone, Mid Interditial Zone , Low Interditial Zone and Subditial Zone.
9: What are some of the challenges for the critters of the intertidal zone? Explain.
The intertidal zone is divided into 5 zones. Each zone has a different lifestyle . As the sea levels rises or go down the critters living there need to adapt to those abrupt changes.Some of the biggest challenges to them to survive is to avoid to dry out ,survive at the different levels of salinity of the sea, dramatic weather changes , intense sunlight and also for some wild animals that can be they predators.
10: How do the intertidal organisms COPE with the harsh environment?
They have to get used to these changes by having their body structure or developing some skills to survive.
11: What are some of the adaptations that help organisms cope with wave action?
The animals living ion the different zones of the inerdital zone have adapt their bodies to these changes . Such as having a dull shell to prevent predators to eat them , crunching up their bodies to keep their normal humedity, atatching very hard to seafloor or rocks and finally hiding down in the sand or behind rocks.

Do: Predicting the Tides
"Lunar Day"
What is the global impact of tides?
"Lunar Day"
- How much time passes between one high tide and the next?
- It needs to pass 12 hours after a high tide so then to have the another high tide, which by the way just happens two times per day.
- How much time passes between low tide and the next high tide?
- In order to have another low tide it needs to pass 12 hours as well.
- Explain how spring and neap tides are created.
- Spring tides are created when the sun and the moon are align making the gravity force combined making really high tides, however when the sun and the moon are in different position such as with an angle of 90 degrees they created what is called neap tides which are moderate tides.
- How many spring and neap tides occur each month? Why?
- It always varies there is not a specific number about how many occur within a month.
- Why does the distance from the earth to the moon or the sun affect the tides?
- As the distance between the earth and the moon or sun changes, the tidal force each produces will vary.
- When will lunar tides be higher, at perigee or apogee? How often does each occur?
- The lunar tides will be highest when the moon is closest to the earth, the" perigee". It takes the moon a month to complete an orbit.
- When will solar tides be higher, at perihelion or aphelion? How often does each occur?
- The solar tides will be highest when the sun is closest to the earth, a point in the earth’s orbit that is called perihelion. It takes the earth a year to complete an orbit around the sun.
- "Do: Life in the Intertidal Zone"
- How does the abundance and diversity of life change across the various intertidal zones?
- There are more cretters in in low zone than in the first zone. This is because the zones more above are exposed to more abrupt chanches than the low one which is inside of the sea.
- Describe how the physical stresses on life vary from the top of the intertidal zone to the bottom.
- Because the top zones are morexposed to abrupt changes there tends to be more life under the sea or in the subductional zone.
- How are these stresses reflected in the types of animals that inhabit the intertidal subzones?
- There are less affected by the abrupt changes in top zones , so there are more animals likely to be live down there
- Living conditions in the intertidal zone are difficult, yet most of it is abundantly populated. What are some of the benefits of intertidal living?
- the harsh conditions in the intertidal zone cut down on competition for food and for space by excluding many animals. And the shallow water transmits the sunlight for bottom-dwelling plants’ need for photosynthesis.
What is the global impact of tides?
- The global impact of tides, when tide currents bounce off seafloor ridges and shells. The disturbing turbulence mixes ocean water, redistributing heat & nutrients, and helps regulate the climate.
- Some of the challenges that people living in coastal areas face is when they buil constructions because by thye high and low levels of tides these may affect these constructions.
- Elctricity can be generted by using off-shore turbulence which function like under-water wind-mills.
