TEST REVIEW FOR WEATHER AND FRONTS

  1. LOOK AT THE PICTURES BELOW.

A B

C D

PLEASE EXPLAIN IN WHAT YOU UNDERSTAND IS HAPPENING IN EACH OF THE PHOTOS BASED ON WHAT YOU KNOW ABOUT HOT AND COLD. Convection currents is occurring. Cooler air/water is denser therefore sinks and as it warms up it becomes less dense and rises.

  1. LOOKING AT PICTURE “D” ABOVE WHAT IS THE MAJOR ENERGY SOURCE CAUSING THE AIR OVER LAND TO HEAT UP, AND BEGIN TO RISE?

Solar heating, energy from the sun

  1. YOU KNOW THAT THE sun WARMS THE AIR OVER LAND, CAUSING IT TO rise _. BASED ON THAT INFORMATION, EXPLAIN WHY THE AIR FLOW IS DIFFERENT FROM DAY TIME TO NIGHT TIME USING THE PICTURE BELOW.

During the day, the sun heats up both the ocean surface and the land. The land absorbs more of the sun’s energy.Water heats up much more slowly than land and so the air above the land will be warmer compared to the air over the ocean. The warm air over the land will rise throughout the day, causing low pressure at the surface. Over the water, high surface pressure will form because of the colder air. The air will sink over the ocean. The wind will blow from the water (higher pressure) over the water to land (lower pressure) over the land causing the sea breeze.

At night, the roles reverse. The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. The ocean hold onto this heat after the sun sets and not lose it as easily. This causes the (low surface pressure) to shift to over the ocean during the night and the (high surface pressure) to move over the land. The wind will blow from the land to the ocean creating the land breeze.

  1. DESCRIBE THE MANNER OR WAY THE LIGHT AND HEAT FROM THE SUN HIT THE EARTH BASED ON THE PICTURE BELOW. The sun receives more direct sunlight at the equator making it warmer than the poles (north and south)
  1. BASED ON THIS PICTURE, THE uneven_ HEATING OF THE EARTH SURFACE CAUSES THE WATER TO BE_warmer NEAR THE EQUATOR AND cooler THE FARTHER YOU GET AWAY FROM THE EQUATOR.
  1. THIS CAUSES THE OCEAN WATER AND AIR IN THE ATMOSPHERE TO MOVE, WHAT DO WE CALL THIS MOVEMENT OF HEAT?

Convection currents

  1. WHEN YOU GOT TO SCHOOL AT 7:55AM THE WEATHER WAS NICE, NOT TOO HOT, NOT TOO COLD. WHEN YOU LEFT SCHOOL TO GO HOME AT 3:40 IT WAS EXTREMELY COLD OUTSIDE, WHAT CAUSED THIS “SUDDEN” CHANGE IN THE TEMPERATURE? A cold front came through (it passed through)

Questions 8-10, you will have to look it up online. We will further discuss this when I return

  1. WHERE DO HURRICANES ORIGINATE (COME FROM), AND WHY? BE SPECIFIC ABOUT THE AREA. Hurricanes need warm moist air from the ocean and can be typically be found/formed near the equator at tropical regions
  1. IN THE FORMATION OF A HURRICANE, WHAT DOES THE OCEAN WATER BEGIN TO DO AS IT GETS REALLY WARM/HOT? As the ocean water gets warmer/hot it begins to evaporate and rise giving more energy for a hurricane to form
  1. WHY DON’T HURRICANES FORM NEAR THE NORTH OR SOUTH POLES? Hurricanes need hot/humid air, the poles are too cold and does not provide sufficient energy for a hurricane to form
  1. WHAT DOES THE WORD “CURRENT” MEAN IN THE PHRASE CONVECTION CURRENT? Movement / flow
  1. WHAT DOES THE OCEAN WATER DO BECAUSE OF THE UNEQUAL heating IT RECEIVES? LIKE THE MAP WE COLORED. DRAW IT WITH THE EQUATOR AND ARROWS EXPLAINING THE MOVEMENT OF THE WATER.
  2. COMPLETE THE TABLE BASE ON THE DEFINITIONS. YOU MAY WANT TO LOOK IN YOUR JOURNAL NOTES.

/ cold_Front - a zone separating two air masses, of which the cooler, denser mass is advancing and replacing the warmer.
/ warm Front- a transition zone between a mass of warm air and the cold air it is replacing.
/ occluded Front - a front between warm and cold air masses that is moving very slowly or not at all.
/ stationary Front - a composite of two fronts, formed as a cold front overtakes a warm or quasi-stationary front. Two types of occlusions can form depending on the relative coldness of the air behind the cold front to the air ahead of the warm or stationary front. A cold occlusion results when the coldest air is behind the cold front and a warm occlusion results when the coldest air is ahead of the warm front.

  1. Describe what is the expected weather to be across the US.

Storms are present in the SouthEast region, but it is clear and sunny in the northern part of the United states. Note: High pressure typically has good weather, low pressure typically has bad weather
