  ( Source )  Study the diagram above and state the two circulation cells that meet at latitudes of 30 degrees North and South of the Equator.         [ 2 marks ] State - express in clear terms  So first of all look for the two command words. Actually look at the diagram, identify where the 30 degree latitude lines. Latitude lines are the ones that go horizontal.  Then write down the two cells that meet at the 30 degree line of latitude. These are Hadley  and Ferrell cells . Note that there are two answers for two marks.  Too easy for you? How about this one? Explain how global atmospheric circulation contributes towards distinctive weather and climate patterns.                                     [ 4 marks ] Explain - set out purposes or reasons So, first of all you need to know something a...

The Queue - is it a micro pilgrimage?

Image
First of all, what is a pilgrimage? Pilgrimage - Wikipedia defines it as "...a journey, often into a unknown or foreign place, where a person goes in search of new or expanded meaning about their self, others, nature or a higher good, through the experience. It can lead to a personal transformation, after which the pilgrim returns to their daily life." We know that people are joining the queue to see the coffin of the Queen for many reasons and some have come from other countries.   ( Source ) The Queue or #thequeue is a temporary pilgrimage of between 6.9 miles between Southwark Park and Westminster Hall with a three mile zig-zagging park in the park. The location of importance in the hall is the body of Queen Elizabeth the Second.   ( Source )  It is interesting to note that the author of a paper " Pilgrims or Tourists ", the Christian Priest Frank Fahey states that "a pilgrim is always in danger of becoming a tourist" and vice versa.

What is one? A thunderstorm or lightning or electrical storm is known for its lightning (and that come descend or ascend in various forms and colours) and its audible noise. If the thunder is quieter, it may be known as a thundershower.  (https://scijinks.gov/thunderstorms-video/thunderstorm_video_poster.png)    What causes one? NOAA (the National Oceanic and Atmospheric Administration) found in the USA states that a thunderstorm needs "three things - moisture, rising unstable air (air that keeps rising once given a nudge) and a lifting mechanism to provide the nudge".  (https://www.youtube.com/watch?v=A6cwPfYaBtA) The sun heats the ground that warms the air above the warmed ground. If the air is "forced" to rise where warm and and cold air or wet and dry air "bumps" into each other and this causes the warm air "to rise as long as as it weighs less and stays warmer than the air around it".  "As a storm rises into freezing air, different ty...

Pollution News

 Taken from The Guardian Weekly 22/4/2022 " Residues of sunscreen show up in Mediterranean seagrass Chemicals used in sunscreen lotions are accumulating in Mediterranean seagrass, a study has found.  Scientists discovered ultraviolet filters in the stems of Posidonia oceania , a seagrass species found on the coast of Mallorca and endemic to the Mediterranean Sea.  The researchers believe the contamination is the result of recreational activities and waste discharges in the tourist destination.  Varying concentrations of sunscreen components, including oxybenzone, benzylidene camphor,  and methyl parabens, were found in samples; while the full effects of the chemicals are unknown, the researchers are concerned about potential harmful effects." Questions to ask: What is meant by the term "endemic"? Why should we worry about contaminated seagrass, it's only at the bottom of the food chain? Have you heard about the Osprey and a pesticide called DDT?
