Question 3 NAME 3 FACTORS THAT EFFECT OCEAN TEMPERATURES. a. Depth the deeper the water is, the less sunlight there is to warm the water, therefore the water is colder b. Seasons less direct sunlight in winter c. Latitude water near the equator is warmer than water near the poles

Question 4 WHAT IMPACT CAN MELTING PACK ICE (SEA ICE) HAVE ON THE ENVIRONMENT? 1. Melting pack ice would dilute the ocean water around it. This would decrease the salinity of the water, causing it to be less dense. This could slow the thermohaline circulation 2. Loss of Habitat 3. Decrease in the reflectivity of the land (less white ice to reflect the sun s rays back to space) More of sun s rays absorbed by the land = warmer temperatures Melting pack ice would NOT cause an increase in sea levels

Question 5 WHAT IMPACT CAN MELTING GLACIERS (LAND ICE) HAVE ON THE ENVIRONMENT? 1. Melting glaciers would dilute the ocean water. This would decrease the salinity of the water, causing it to be less dense. This could cause a slowing of the thermohaline circulation 2. The addition of the glacial water to the oceans would cause an increase in sea level. 3. Decrease in the reflectivity of the land (less white ice to reflect the sun s rays back to space) More of sun s rays absorbed by the land = warmer temperatures

QUESTION 6 WHAT WOULD HAPPEN TO MONTREAL IF ALL OF THE GLACIERS MELTED? The addition of water from melting glaciers would increase the sea level, eventually leading to Montreal being submerged in water with the exception of the top of Mont Royal.

QUESTION 7 WHAT EFFECT DOES THE EARTH S ROTATION HAVE ON SEA CURRENTS? The Earth s rotation (spinning of earth on it s axis) causes objects (wind and water currents) to be deflected to the right in the northern hemisphere and to the left in the southern hemisphere.

Earth s Rotational Effect on Currents

QUESTION 8 TRUE OR FALSE? A) IS THE THERMOHALINE CIRCULATION RESPONSIBLE FOR THE SEASONS? FALSE. The cause for the seasons is the Earth s tilt allowing for more or less direct sunlight to hit different areas of the Earth depending on it s location in the orbit around the Sun at different times of the year. However, the thermohaline circulation does play a role in regulating the climate around the world.

QUESTION 8 TRUE OR FALSE? B) WATER IS MORE DENSE IN SUBSURFACE CURRENTS. TRUE. When sea ice is formed, the water left in the ocean becomes more salty. The water then sinks as it becomes more dense than the less salty water. As the water sinks, it gets further away from the Sun causing it to get colder. Water that is COLD and VERY SALTY then forms the subsurface currents.

QUESTION 8 TRUE OR FALSE? C) THE TIDES ARE CAUSED ONLY BY THE GRAVITATIONAL PULL OF THE SUN. FALSE The main cause for the tides on Earth is the gravitational pull of the Moon. The Moon s gravitational pull has more of an effect on the tides on Earth because the Moon is closer to the Earth than the Sun is.

QUESTION 8 TRUE OR FALSE? D) AT ANY ONE TIME THERE ARE TWO LOW TIDES AND TWO HIGH TIDES ON EARTH. TRUE. The gravitational pull of the moon causes there to be high tides on the side facing the moon and directly opposite. The low tides are perpendicular (at right angles) to the high tides.

During Neap Tides, there are still high and low tides. However, the low tides are higher than low tides during Spring tides.

QUESTION 9 EXPLAIN THE THERMOCLINE AND HOW IT WORKS. The thermocline is the curve that describes how the ocean gets colder as it gets deeper. Near the surface of the ocean, the water is warmed by the sun. As you go deeper, there is less sun reaching those waters, causing it to get colder and colder.

QUESTION 10 WHAT EFFECT DOES THE THERMOHALINE CIRCULATION HAVE ON THE CLIMATE OF THE POLAR REGIONS? The circulating of warm water up to polar regions allows for the climate of polar regions to be milder. The release of HEAT from the warm water to the surrounding air allows the climate of polar regions to be milder (warmer, less cold).

Release of Heat
