Question | Answer |
what is the periodic rise and fall of the eaarths oceans surface caused by the gravitational force between earth and the moon and between earth and the sun | tides |
occurs when earth, the moon and the sun form a right angle and has the lowest tidal range | neap tide |
surface wave currents are formed by what | wind |
the average level of the ocean's surface at any given time | sealevel |
a spring tide is a tide that has the largest what | tidal range |
a neap tide is a tide that has the lowest what | tidal range |
the bottom of the wave | trough |
the highest part of the wave | crest |
from crest to crest or from trough to trough | wavelength |
to trough to crest | wave height |
how shallow does water need to be for a breaker to form | the water has to be more shallow than the base is |
what is a tsunami | a huge wave caused by a disturbance in the ocean |
which disturbance can cause a tsunami | earthquakes |
what causes tides | gravitational pull on the earth, moon, and sun |
why does the largest tidal range occur during a spring tide | more gravity pull |
why does a neap tide have the lowest tidal range | low gravity pull |
what is the position of the earth, sun, and moon at a spring tide | strait line |
what is the position of the earth, sun, and moon at a neap tide | right angle |
the what distance between the crest and the trough of a wave is the wave height | vertical |
the what distane between the crest to crest is the wavelength | horizontal |
when a wave reaches a certain height and cant support the crest it collapses, what is this called | breaker |
besides an earthquake what else is a disturbance that can cause a tsunami | landslides, volcanic eruptions, and glaciers |
can a breaker form at any size | no |
how many neap tides are there in a single day | 2 |
how many spring tides are there in a single day | 1 |
when do the neap tides occur | morning, and late afternoon |
when do the spring tides occur | all afternoon |
