Natural Resources
Name two renewable natural resources.
solar, wind, biomass, etc.
What is a water footprint?
A way to calculate how our daily consumption of goods uses water and how much water and shows the problems of water depletion and pollution.
Define mineral
a solid inorganic substance usually found in rocks
What is the major driving factor of the water cycle?
The sun.
Why is the human population having an impact on our natural resources? Give 2-3 reasons and support them.
More land is needed for crops, more people to feed, more limited resources spread over a greater population(all acceptable)
Define natural resources.
things that humans use that occur naturally in nature.
Is water a renewable or non-renewable resource?
It can be both. It is renewable because of the water cycle. It is non-renewable because it is not being replenished as fast as it is being used.
What are three rock types?
igneous, sedimentary and metamorphic
In order to conserve water, what habits could you change?
Save energy, buy less "stuff", use less water for watering, change diet to less meat.
What was the Industrial Revolution?
The Industrial Revolution was the transition to new manufacturing processes This transition included going from hand production methods to machines, new chemical manufacturing, and iron production processes, the increasing use of steam power and water power, the development of machine tools, and the rise of the mechanized factory system. The Industrial Revolution also led to an unprecedented rise in the rate of population growth.
Fossil fuels are a _______________ resource
non-renewable
Explain condensation and give an example.
Condensation is a process when water vapor returns to the liquid phase. Example: clouds forming from water vapor.
What is the rock cycle?
A cycle in which physical changes—such as melting, cooling, eroding, compacting, cementing, heating, forming pressure continuously change different types of rock into each other such as igneous, sedimentary and metamorphic.
Humans have had negative impacts on the water cycle. Name and explain two.
Overuse of water-depleting aquifers
Pollution-chemicals, fertilizers, herbicides into water table
(all acceptable)
What was the Green Revolution?
The great increase in production of food grains (especially wheat and rice) resulted in large part from the introduction into developing countries of new, high-yielding varieties, beginning in the mid-20th century. The new varieties required large amounts of chemical fertilizers, herbicides, and pesticides to produce their high yields, raising concerns about cost and potentially harmful environmental effects.
What are three advantages to using non-renewable resources?
They are efficient, the infrastructure is already being used, cost-efficient.
What is evapotranspiration?
Plants transpire or release water vapor from their leaves which then evaporates.
Give three facts for the mineral copper.
Copper is a metal, used in electrical wiring, the material that the Statue of Liberty is made of (all acceptable)
Water is one of our most valuable __________.
resources
What is climate change? Why do we no longer use the term Global Warming?
Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil, and gas.
Burning fossil fuels generates greenhouse gas emissions that act like a blanket wrapped around the Earth, trapping the sun’s heat and raising temperatures.
Climate change is more accurate because some areas will become much colder and not warm.
Name three ways that you use natural resources every day.
Possible answers: drinking water, heating homes, making food, cell phone components, paper, etc.
Only _____________% of the Earth's water is fresh water and most of the is in the form of __________, leaving about __________% as accessible freshwater.
3%, ice, 1%
How are sedimentary rocks formed?
Over time, through erosion and weathering, sediments runoff and become a layer which through compacting and cementation and many years forms sedimentary rock
Negative impacts from humans on the water cycle include:
draining wetlands, overuse, damning rivers (all acceptable)
What small contributions can you make, at your age to conserve resources and lessen the human impact on the environment? Give three contributions and explain.
(All acceptable answers)
Shorten showers, buy less, eat one vegetarian meal a week, recycle
