chapter 8.2

vocabulary-ocean waves and tides

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
