Unit 2 FINAL

Question 1

What is a Boundary?

Answer 1

When two air masses collide

Question 2

What is an example of a Low pressure system?

Answer 2

Boundary

Question 3

Explain a Low Pressure system:

Answer 3

When air is being lifted, movement of a cold front through a warm front, low Pressure Systems often cause severe rainfall/thunderstorms

Question 4

Explain a High Pressure System:

Answer 4

It pushes air away, air descends, associated with drier weather conditions and clear skies

Question 5

What is cold front?

Answer 5

The leading edge of a cooler mass of air at ground level replaces a warmer mass of air

Question 6

What is a warm front?

Answer 6

a relatively warm, moist air mass slides up and over a cold air mass

Question 7

What is weather?

Answer 7

The state of the atmosphere at a particular point in time

Question 8

What is a stationary front?

Answer 8

When a cold front or warm front stops moving

Question 9

What is an occluded front?

Answer 9

When a cold front catches up and over-takes a warm front

Question 10

What kind of front produces gentle rain fall?

Answer 10

Warm front

Question 11

What kind of front involves three different air masses and what are they?

Answer 11

Occluded front
Made up from two cold fronts and a warm front

Question 12

Which one is most likely to produce violent thunderstorms?

Answer 12

Cold front

Question 13

Which front is most likely to last for days?

Answer 13

Stationary front

Question 14

Which front is likely to be followed by warm temperatures and higher humidity?

Answer 14

Warm fronts

Question 15

Why would two air masses stay separate from one another?

Answer 15

Because their density is different (one is heavier than the other)

Question 16

Along the front which air is forced upward?

Answer 16

Warm front, less dense air

Question 17

Which kind of front is best for farmers, why?

Answer 17

Warm front is better for farmers because it brings sunshine and light storms, perfect for crops and farming

Question 18

What are the causes of different water current?

Answer 18

Primary forces like solar heat wind gravity and secondary forces

Question 19

How does water density affect to set up currents from poles to the equator and vice versa?

Answer 19

By cold water moving down in warm water, moving up. The warm water moves towards the poles, and the cold water moves towards the equator.

Question 20

How is the movement of currents influence by prevailing winds? Give some examples:

Answer 20

By winds, pulling surface water with them, creating currents. For example, gravity, wind, and coriolis force

Question 21

How do currents affect the temperature?

Answer 21

By bringing warm currents to flow parallel to the east coast of the warm continents in tropical and subtropical latitudes. In result, warm and rainy climates.

Question 22

Where are cold and warm currents found?

Answer 22

Cold currents are found near the equator and warm currents are found in the poles (this is too, even though the temperatures through the planet)

Question 23

Describe the relationship between atmospheric pressure and weather:

Answer 23

When the weather is warm, the pressure starts to go up. When the weather gets cold, the pressure goes down.

Question 24

Explain possible causes for stormy weather:

Answer 24

Possible causes a stormy weather is when the pressure is around 1010 or below

Question 25

What is latitude?

Answer 25

The distance north and south of the equator

Question 26

What does weather include? (Hint: 5 examples)

Answer 26

heat, dryness, wind, rain, and sunshine
