Climate Change Flashcards
What is the natural, greenhouse effect and wise important to life on earth?
Earths atmosphere, trapped some of the suns energy warming the planet. This helps maintain the earths temperature.
What are the four main gases that contribute to climate change?
Carbon dioxide, methane, nitrous oxide, water vapour
What does the term albedo mean? Provide one example of a surface that has a high albedo and one that has a low albedo?
The measure of how much sunlight surface reflects back into space high albedo means a surface that reflects most of the sunlight. Low albedo means a surface that absorbs most of the sunlight
high albedo = snow/ice
low albedo = soil.
Describe the process of using growth rings on trees to derive information about climate
The number of tree rings reveals the age of a tree. The spacing of the tree reveals how warm and wet the summers were in the region. They were grown wider. Spacing indicates greater growth during a warm, wet season. Thin spacing indicates little growth during a cool dry season.
What is the difference between natural greenhouse effect and anthropogenic greenhouse effect?
Natural means it happens naturally with no human interaction. Anthropogenic means it happens due to human interaction.
Why did the level of greenhouse gas emissions begin to increase during the industrial revolution?
There’s been major changes in agriculture, manufacturing, mining, transport, and technology
What is the Greenland ice core project? What type of information do scientist find when they analyze the ice cores?
Scientist drill into ice glaciers and extract samples each year snowfall is recorded as a distinct layer. The thickness of the layer reveals the amount of snowfall by extracting and melting a layer from the core scientist can analyze atmospheric gas concentration for a given year.
