This happens when the normal winds weaken which allows the warm water that is usually found in the western Pacific change direction and instead move towards the east. This warm water replaces the cold water which is normally found near the surface of the eastern Pacific. All these occurrences are what affects a lot of weather patterns in many parts of the
EXERCISE 10 PROBLEMS – PART I The following questions are based on the maps of average January sea-level temperatures (Figure 10-1) and average July sea-level temperatures (Figure 10-2): 1. Is the temperature contrast between the equator and the Arctic region greatest in the winter or summer? Temperature contrast between the equator and the Arctic region is greatest in the winter. Temperatures near or at the equator only change a few degrees between winter and summer, while the Arctic region changes up to 40 degrees between the seasons. 2.

The evidence of sea floor spreading was further supported by Vine and Drummond, who studied the magnetic pattern of the sea floor. They found that the Earth’s magnetic field changes over time, because as magma from the mantle rises to the crust it cools but the basalt will align to the field it cools to. It is also found that on either side of mid oceanic ridges there were symmetrical magnetic patterns, so suggesting that the ocean was created at the mid oceanic ridges and as new ocean floor cooled, it pushed the crust away. Both Hess and Vine and Drummond found evidence that is crucial to the explanation of how continental drift happened, and it is very important in the development of geologists understanding, however other people found evidence to support continental drift also. Dan McKenzie went on to further explain sea floor spreading, being able to explain why new crust was made at mid oceanic ridges.
-”Wegner used the shapes of matching shorelines on different continents as a supporting piece of evidence for continental drift. 3. Describe Earth's magnetic field, including how it has changed through time. -Similar to a simple bar magnet, ends have opposite polarities that cause magnetic objects to align parallel to it’s magnetic field. Poles have wandered from geographical position over the years.
What about at an increased temperature? Answer = The weather may be calm with decreased temperatures verses a warmer temperature. The sun heats the water to evaporate and to produce water vapors that transform into clouds. According to our lab manual, clouds form at many different altitudes in the troposphere when water vapor in warm air rises and cools. Experiment 1: Water Movement POST LAB QUESTIONS 1.
While the air pressure increased the winds decrease as iso bars spread apart and wind is no longer moving at an abrupt pace. This is called a high pressure area, where air is more stationary not moving fast an across the iso bars. 4. What explains the decrease in the intensity of Hurricane Katrina between 29 and 30 August 2005? From august 29th to august 30th hurricane Katrina made landfall and along with land fall lost its fuel source.
There could be a decrease in climate related disasters, an increase in the production of food, and a healthier human population (Noble, 2007). Warmer winters would mean fewer deathes for the elderly (Skeptical Science, 2012) fewer cold weather injuries and less
Due to this convergence (where winds move to a center point), air is forced to rise over that area. If enough moisture is available, the rising air cools and condenses (as cold air cannot hold water vapor below a certain temperature) into tiny water droplets which constitute the cloud. So, low pressure areas are usually the birth-place of clouds. Sometimes, particularly in the winter, fog forms over a high pressure area due to radiation cooling(due to clear sky conditions over a high pressure area).This fog sometimes lift and forms thick low cloud called "anticyclone gloom".

This happens when high-pressure returns, creating an inversion with colder air near the earth's surface than aloft. This in turn causes moisture on the ground to condense into a low
