Weather and Climate

We are back from the long June Holidays and we learnt about the weather and climate on the first Geography lesson of Term 3.The difference between weather and climate is thatclimate talks about long term changes while weather talks about short term changes.
Elements of Weather- Temperature
There are two factors that affect the temperature and they are the location and the rotation of the Earth. An important thing to note is 'where you are located on Earth will affect how you experience weather and climate'.The part of the Earth that are between the latitude of 10 degrees North and 10 degrees South (including the Equator, which have a latitude of 0 degrees) is known as Tropical Equatorial and it receives the most amount of sunlight. It receives more heat than other parts of the Earth as it is nearer to the Sun and the heat rays travel less therefore the heat is more intense. The part of the Earth that is have a latitude of 23.5 degrees North and South is known as the Tropical Monsoon. The part that is 60 degrees North and South is known as Temperate region, where the countries located there will experience the four seasons.Finally, the North and South poles are known as Polar.
Tropical regions rain more than temperate regions.

Why do the radiation from the ground affect the temperature that is taken from a thermometer?
