Term
What does geology have to do with Earth's climate?
Definition
There is geologic evidence of changes in Earth's climate.
Term
What are some examples of natural geologic phenomena that may impact climate?
Definition
Volcanoes, continental displacement
Term
Methane hydrates are compounds made of Carbon and Hydrogen. What is released when these break down?
Definition
Carbon dioxide
Term
What compound is being released by the burning of fossil fuels?
Definition
Carbon dioxide
Term
Both Carbon Dioxide and Methane are greenhouse gases. What do these do?
Definition
These gases trap the heat around our planet causing the global temperature to rise.
Term
Knowing that naturally occurring geologic phenomena have remained relatively constant, what can be said about their impact on climate change?
Definition
The naturally occurring geologic phenomena alone cannot account for climate change.
Term
What is meant by the statement, "It is the sole agent."
Definition
This means, "It is the only agent."
Term
Define the term, phenomena.
Definition
This is an observable occurrence.
Term
Fill in the blank: Continued burning of _______, _______, and _______ could increase the total carbon emission to that above which occurred 55 million years ago.
Definition
Oil, gas, coal
Term
What is meant when we are trying to develop a recovery that will reduce the global temperatures?
Definition
This means we want to return to previous, lower global temperatures.
Term
Carbon emissions from volcanoes account for ______ that which is released annually on Earth.
Definition
1%
Term
Melting ice on Earth may _______ the reflection of the sun's energy into space.
Definition
reduce
Term
It is reasonable to conclude from the evidence that emitting _________ ________ into the atmosphere is unwise.
Definition
carbon dioxide
Term
A large part of the modern increase in carbon dioxide is the result of burning various types of __________ ___________.
Definition
fossil fuels
Term
_________________ have at least some control over climate change.
Definition
Humans
Term
What does de-forestation have to do with climate change?
Definition
De-forestation results in fewer trees which would have been able to take in some of the carbon dioxide and therefore adds to climate change.
Term
What is noticed about the levels of carbon dioxide over the past 800,000 years?
Definition
There have been regular cycles of fluctuation.
Term
What is different over the past 100 years related to the levels of carbon dioxide compared to the past 800,000 years?
Definition
The current level of carbon dioxide is much higher than any other point in the past 800,000 years.
Term
The Earth is tilted (toward / away from) the sun during summer.
Definition
toward
Term
The Earth is tilted (toward / away from) the sun during winter.
Definition
away from
Term
In winter, the sun's rays are ..... than in the summer.
Definition
at a greater angle
Term
______________ is the day to day conditions on Earth.
Definition
Weather
Term
_____________ is the overall conditions on Earth.
Definition
Climate
Term
List the six conditions that impact weather.
Definition
Temperature
Atmospheric Pressure
Wind
Humidity
Precipitation
Cloudiness
Term
What can happen to crops and animals when they experience shifting weather and climate?
Definition
This puts stress on the organisms - may struggle to survive
Term
If climate changes continue, habitat zones in the Northern hemisphere will shift....
Definition
further North
Term
List at least three ways to address climate change
Definition
1. Allocate more green space/plant more vegetation
2. Use energy sources that do not emit carbon dioxide
3. Carpool or use public transportation
