1.1-1.3- Atmosphere, Climate Change, Human Activity

Question 1

Explain why low latitude locations receive more heat than places close to the poles.

Answer 1

Low latitude locations receive more heat than others as they are closer to the sun and the rays are more concentrate don the surface as they don’t have to travel as far. This allows the heat to be kept without being lost in the atmosphere.

Question 2

How is a high pressure different to a low pressure area? How does the weather differ?

Answer 2

.

Question 3

What are atmospheric circulation cells called?

Answer 3

Hadley cell, Ferrel cell and Polar cell

Question 4

Where is heat moved from and to? (Think poles and equator)

Answer 4

Heat is moved from the equator out towards the poles throughout the cells going through high and low pressure zones.

Question 5

How do atmospheric circulation cells move heat around the world?

Answer 5

They rotate around the cells forcing into a higher latitude and going up towards the uppermost point

Question 6

How do ocean currents move heat from the equator to the poles? How does the gulf stream work?

Answer 6

They work together to move heat and fresh water across the globe. Wind-driven and ocean-current circulations move warm water toward the poles and colder water toward the equator.

Question 7

Explain how atmospheric circulation causes high pressure areas (dry) places like Tindouf.

Answer 7

High pressure areas receive less rainfall as the suns radiation is intense here.

Question 8

Explain how atmospheric circulation causes low pressure areas (wet) places like Singapore.

Answer 8

The sun’s radiation causes the tropical air to rise and become less dense , it transfers heat to the atmosphere, it cools and creates clouds and rain occurs.

Question 9

What are the four different natural factors that have caused world climates to change over the last 400,000 years?

Answer 9

variations in the energy from the sun
the way the earth orbits the sun
the way oceans transfer heat from one area to another
volcanic activity (dust particles released in an eruption can disrupt the atmosphere)

Question 10

Orbit, Tilt and Wobble - what are these and why so they cause variations?

Answer 10

When the earth is more vertical, it orbits in a circular way and makes us slightly warmer.
