Define a Hadley Cell
Explain how it works
A Hadley Cell is a large-scale atmospheric convection current that transports heat from the tropics toward the poles, creating distinct weather patterns.
It works by warming and rising air at the equator, leading to cloud formation and rain, then cooling and flowing poleward in the upper atmosphere before sinking in subtropical regions and returning equatorward as trade winds. This cycle results in humid, rainy conditions near the equator and dry, arid conditions in the subtropics.
Describe the difference between El Nino and La Nina referring to the wind
El Nino’s wind pattern goes from west to east, while La Nina goes from east to west in a stronger form than average.
what is the main difference in climate and weather
climate is long term weather patterns
weather is the state of the atmosphere at a place and time as regards heat
If the Earth is in El Nino, which direction is the thermocline sloped to?
East, towards South America
Define the word Albedo
Albedo is the proportion of light that is reflected by a surface
Define the word Insolation
Insolation is the amount of solar radiation reaching an area measured in Watts/m^2
What is the hottest layer of Earth’s atmosphere?
The Thermosphere is the the hottest layer due to it’s high absorbtion of solar energy reaching up to 3,100F°
What does ENSO stand for?
El Niño Southern Oscillation
True or False: ENSO only affects weather patterns in the Pacific Ocean region.
False
Which wind pattern is associated with El Niño conditions?
Weakening of the trade winds
What is the primary effect of La Niña on global weather patterns?
Increased rainfall in the western Pacific and drier conditions in the eastern Pacific
Which direction does the wind blow from 30° to 60°
west to east
The eastern and western trade winds blow which direction?
They blow east to west.
What regions are effected by El Niño
Latin America (especially the northern and southeastern parts), Southern Africa, and Southeast Asia
What is the coldest layer of Earth’s atmosphere?
The Mesosphere is the the coldest layer due to it’s having the least density of molecules to absorb the sun reaching down to -150F°
What regions are effected by La Niña
Southeast Asia, Australia.
What is the primary process by which carbon is removed from the atmosphere?
Photosynthesis
True or False: Nitrogen fixation is the process that converts atmospheric nitrogen into a usable form for plants.
True
What are the three main processes of the carbon cycle?
Photosynthesis, respiration, and decomposition
Which organisms are primarily responsible for nitrogen fixation?
Certain bacteria, including those in the root nodules of legumes
Multiple Choice: Which of the following is a key step in the phosphorus cycle?
A) Nitrification
B) Weathering
C) Denitrification
D) Photosynthesis
B) Weathering
Short Answer: What is the role of decomposers in the nitrogen cycle?
Decomposers break down organic matter, releasing nitrogen back into the soil.
True or False: Phosphorus is abundant in the atmosphere.
False
What human activities can disrupt the nitrogen cycle?
Use of nitrogen-based fertilizers and fossil fuel use
