Natural Disruptions to Ecosystems
These are often caused by earthquakes under the water that can completely wipeout ecosystems.
Tsunami's!
What is the most abundant gas in the atmosphere?
Nitrogen
What are two factors that can impact an species survivorship curve?
Parental care, access to clean water, food availability, number of offspring born, etc.
What is TFR (total fertility rate)?
Amount of children a woman will have in her lifetime.
You have been in this room for 6 weeks. What classroom # is this?
G113
Explain the formation of soil.
Rocks are broken down by water, wind, ice, plants, or animals. Overtime this becomes deeper and allows for more plants to grow and extend their roots.
Explain the general idea of global air circulation. Be sure to talk about how air moves between the equator and the poles.
Warm air becomes less dense and rises at the equator. It can't sink back here because of all the warm rising it. It then moves towards the cold poles, becomes more dense and sinks. Creating a global convection current.
How is population growth impacted by available resources and space?
Without available space, organisms can not have a home to spread roots, raise young, etc.
Available resources such as sunlight, water, and food are all necessary for survival. If there is a lot of these resources growth will be abundant... a lack in these resources will limit the growth.
Why do countries with high TFR typically also have high infant mortality?
They need more children to replace those that die.
Our class averaged 11 survivors for the panther lab... never meeting the carrying capacity of 17 surviving panthers... Why?
Greed!!!!
Explain how a plate boundary map can be used to show locations of earthquakes, volcanoes, and volcanic islands.
Plate interactions take place at boundaries and create those landforms. Different landforms are created from different interactions.
How does the angle of isolation impact the climate of an area?
The closer to the equator the more direct the sunlight, this leads to warmer temperatures.
Locations closer to the poles have a lower angle of direct sunlight, this leads to colder temperatures.
What is carrying capacity?
The number of organisms an ecosystem can successful support.
Name two traits of a preindustrial/ less developed/ stage 1 country.
We are talking about a country that has not yet made the agrarian to industrial transition
Typically very poor (low GDP)
Typically high death rate & high infant mortality
High TFR for replacement children & agricultural labor
Describe the role of island biography in evolution.
As organisms travel and inhabit new lands they have to adapt to new ecosystems. This could cause changes in beak size, what foods they eat, and even color of skin/ fur to match new surroundings.
Why do earthquakes occur?
When the stress becomes too great between locked plates, causing earthquakes.
Explain what el Nino does to the weather of the west coast of America?
Warmer weather with increased precipitation.
What are two factors that limit human population growth?
High death rate
High infant mortality rate
Increased development (education & affluence)
Increased education for women
Delayed age of first child
Postponement of marriage age
How does a highly developed country survive if it has low birthrates and low death rates?
The birth rates are still higher than death rates, leading to a small growth percentage.
Anthropogenic activities can disrupt ecosystem services, potentially resulting in economic and ecological consequences. Give an example with explanation of impacts.

What is the difference between Primary and Secondary Succession? Be sure to talk about the length of time each would take as well as what each starts with.
Primary starts with bare rock and can take a long period of time, depending on the climate.
Secondary succession starts with soil but no vegetation, it takes a shorter period of time, around 100 years.
Why does Salisbury have a lower average temperature than Baltimore City, even though it is closer to the equator?
Closer to 2 large bodies of water which causes the area to have lots of wind all year. This proximity to large bodies of water also causes it to rain more which will also cause the temperature to drop.
Name two characteristics of a stable age structure diagram. (Ex. Spain, Portugal, Greece)
-High GDP
-Long life expectancy
-Low infant mortality
-Low birth rates
-Educated women
The US has seen its population growth rate drop from 1.1% in 2000 to .4% in 2020. What do you think has caused this?
War in Afghanistan 2001 - 2021
Invasion of Iraq 2003
Recession 2008
Covid 2020 - present
Explain how the presence of mountains can affect the climates of areas. Be sure to explain how rain shadows are created.
As air is blown across an area and meets a mountain the air can not go through the mountain. Instead the cloud rises and releases all rain on the windward side. On the opposite side a rain shadow is created with a warmer drier climate.
