|---|---|---|---|---|---|
| why does california have many rocky beaches? | the high energy of the waves erodes the cliffs along the shoreline leaving large boulders and cobbles
🗑
|
||||
| what is the effect of tsunamis on california? | because there is tectonic activity throughout the pacific ocean California coast is at risk from tsunamis
🗑
|
||||
| why are there no hurricanes in california? | because the California current brings cold water to the California coast from the northern latitudes
🗑
|
||||
| what are the habitats of the sea life on california? | rocky shores, intertidal zone
🗑
|
||||
| what is the impact of humans on the california coast? | it is large, because habitat is lost many species are lost
🗑
|
||||
| what are the two types ocean currents | surface currents and deep ocean currents
🗑
|
||||
| what are their influences | surface:produce whitecaps,causes waves to crash, on the surface
deep ocean: density drives it, transports water, heat, nutrients, animals, plants, and ships
🗑
|
||||
| how is energy and heat transferred | energy: sun
heat: ocean currents
🗑
|
||||
| what are the two major currents that effect California | California current and Davidson current
🗑
|
||||
| what are their characteristics | California current:brings cold water to the California coast, wide, slow-moving, cold-water current, brings cold water from the northern latitudes
Davidson current:narrow, warm water current, flows northward, from lower latitudes to higher latitudes,
🗑
|
||||
| what is the Coriolis effect on the ocean | caused by earth spinning on its axis, currents tend to move in a clockwise pattern in the northern hemisphere and counter clockwise in the southern hemisphere
🗑
|
||||
| how do density and deep ocean currents interact | density drives deep ocean currents
🗑
|
||||
| what is a gyre and how does it influence the ocean | a gyre is a cycle of ocean currents, it influences the direction the current will flow
🗑
|
||||
| what are the special currents | special currents: Gulf Stream current, Antarctic Circumpolar Current
🗑
|
||||
| what are their effects | Gulf Stream: causes climate in Europe to be milder despite its high altitude
antarctic circumpolar current: continuous flow of water, driven in an east ward direction around the southern part of earth by strong westerlies
🗑
|
||||
| what is the effects of el nino and la nina on ocean currents | El Nino: droughts, increased rain and flooding
La Nina: changes weather and ocean currents
