Warm and Moist

Question 14

What is another word for a density boundary?

Answer 14

A front

Question 15

What is the Hydrostatic Relationship?

Answer 15

Height and Pressure Relationship

Question 16

3 Units of Pressure

Answer 16

hPa, mb and inches of Mercury

Question 17

As height increases, pressure……..

Answer 17

Decreases

Question 18

What is the difference between High and Low Pressure?

Answer 18

High Pressure indicates a high mass and this forces air DOWN where as Low Pressure indicates a low mass and this forces air UP

Question 19

What is a black body? And how does black body radiation occur?

Answer 19

A theoretical object that emits electromagnetic radiation with efficiency.

Black body radiation occurs as a result of incoming solar radiator above absolute zero
