Paper 1 : Hazardous earth : Climate Flashcards
Global atmospheric circulation definition
Creates wind across the planet and leads to areas of high rainfall, like the tropical rainforests, and areas of dry, sinking air that creates deserts
Atmosphere def
gases surrounding the earth or another planet
circulation def
movement to and from or around something
explain why diff latitudes (eg equator) receive diff amounts of sun energy
equator receives more energy from suna s raidation from sun as its rays have a smaller distance to travel
As latitude increases (as u move away from equator) the distance also increases which reduces the amount of energy transferred, ie equator is closest to sun so air is warm and air at the north and south poles is colder as it’s further away
Main (2) features of the Earth’s energy balance
1 = there is a net gain of solar energy in the tropical latitudes and a net loss towards the poles 2 = tropical latitudes receive more of the Sun's energy than polar regions
what is albedo
white spaces (eg snow and ice), these reflect energy\
why is there a net loss of hear in north / south pole
because of lots of albedo places
explain the diff between high and low pressure
High pressure is when air is cold and dry and air is descending/ forced downwards. there are heavy sinks here. Low pressure is when air is war and rises / is forced upwards resulting in condensation, cloud formation and precipitation
