Question 11

endermic species

Answer 11

species specifically adapted to live in that environment

Question 12

factors that determine characteristics and location of biomes

Answer 12

climate
latitude
winds
air pressure

Question 13

factor - latitude

Answer 13

radiation is more concentrated at the equator and more disperse at the poles
– latitude influences climate

Question 14

factor - high and low air pressure

Answer 14

differences in temperature influence air pressures around the world
low pressure - warm air rises
high pressure - cold air sinks

Question 15

factor - winds

Answer 15

continual transfers of wind maintain the pressure belts which create different climatic zones
