Differences in air pressure drive the global wind system on earth. Which term describes polar winds that blow from east to west?

marshall27 [118]

Answer: Polar Easterlies

Explanation: Winds flow from high pressure areas to low pressure areas. They originate in the north and south pole creating high pressure zones which generates an outflow. This outflow is then directed from east to west and hence the term used to describe these winds is Polar Easterlies.

Answer:

1. B, D,

2.A, F

Explanation:

1. According to the law of conservation of mass, In a course of chemical reaction, matter can neither be created nor destroyed but can be changed from one form to another. This means the amount of matter at the begining and ending of a reaction must be thesame.

2. Chemical reaction is not easily reversible. when gas is produced, provided the reaction system is an open system, the gas cannot be recovered and the reactants cannot be recovered from the products. likewise color change are attributed to chemical reaction
