Name: Score:62 Multiple choice questions
Term 1 of 62
How are tides caused
-When Sun, Earth and Moon from a right angle
-Occurs during 1st and 3rd quarter moon
-Not a strong gravitational pull
-the gravitational pull between the Sun, Earth and Moon
-Moon's gravity pulls on the Earth, pulling the ocean waters toward the Moon
-This pull creates a bulge of water on Earth
-The bulge on the exact opposite side of the Earth is created by centrifugal forces as Earth
rotates
-These bulges create high tides and on side of Earth with no bulge is low tides
-Oxygen increases at the surface due to wave action/wind/mixing of air.
-Oxygen increases by the presence of photosynthetic phytoplankton producing oxygen
-Oxygen is used up by marine organisms during respiration decreasing oxygen
-Oxygen increases as depth increases due to solubility of gases is greater when
temperature decrease.
an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor
occurs when convection currents rise in the mantle beneath the oceanic crust and create
magma where two tectonic plates meet at a divergent boundary.
,Term 2 of 62
Explain why India experiences a wet summer monsoon
Volcanoes release carbon dioxide, sulfur dioxide, chlorine from hydrochloric gas, flourine
gas
In the summer months, from May until August, the land heats up quickly and there is
relatively large temperature difference between Central Asia and the Indian Ocean. Air over
the land warms, becomes less dense and rises. this draws in air saturated with water vapor
from the Indian Ocean, from a south-westerly direction. The summer monsoons bring
thunderstorms and exceptionally heavy rain. It has been estimated that these summer
monsoons bring over 80% of India's annual rainfall.
-Dissolution of atmospheric gases from either mixing of air or volcanic eruptions
-Carbon dioxide, sulpher dioxide, chlorine dissolve with water and change the pH more
acidic
Must be over warm sea water (with a temp of at least 26.5 degrees Celsius) and must be in a
low pressure area where evaporation of water occurs. As the water vapor rises, it condenses
and releases large amounts of heat energy (latent heat of condensation). This heat energy
further increases evaporation, driving the development of the cyclone. As a result of the
rotation of the Earth and the Coriolis Effect, the whole cyclone system starts to spin.
Term 3 of 62
Littoral Zone
Vertical movement of cold deep water that reaches the surface caused by costal slope or
mid ocean ridge and brings nutrients to the surface
Movement of water in one direction
The difference in height between the highest high and lowest low tides
Area between high and low water mark/areas submerged at high tide and exposed at low
tides
, Term 4 of 62
Estuary
-Blackish Water
-Low dissolved oxygen
-Low wave action
-Depositional
-Fine, muddy silt substrate
-Seaweed, fish algae
-Occurs during the day
-Land is warmer than sea from the sun
-Wind direction blows from sea to land
-Area of high to low air pressure
-When Sun, Earth and Moon from a right angle
-Occurs during 1st and 3rd quarter moon
-Not a strong gravitational pull
Normally water off coast of South America is cool, during El Nino year the winds weakening
and lack of upwelling, _______________ warmer waters of the coast of South America.
