A natural resource that can be replenished more quickly than it is consumed. Ex: trees
What is a renewable resource?
100
Before a scientist can make a hypothesis, they must first do this.
What is make an observation/ask a question?
100
The basic unit of matter.
What is an atom?
100
When an event can be both an input and an output to a system; can be positive or negative.
What is a feedback loop?
100
This consists of all of the living or once-living things and the nonliving parts of the environment with which they interact. The most broad sphere.
What is the biosphere?
200
These are examples of non-renewable resources; they are burned in order to extract energy.
What are fossil fuels?
200
A testable idea that attempts to explain a phenomenon or answer a scientific question.
What is a hypothesis?
200
Found in the center of an atom; contains protons and neutrons.
What is a nucleus?
200
This type of feedback loop drives a system towards an extreme.
What is a positive feedback loop?
200
This is made up of all of the rock on or below the Earth's surface.
What is the geosphere?
300
This term is used to describe the effect that humans have on the ecosystem in terms of the amount of land and water they need to survive.
What is ecological footprint?
300
In an experiment, this is the variable that we monitor and measure for changes.
What is the dependent variable?
300
Water is able to make this type of bond, which allows for things like adhesion and cohesion to take place.
What is hydrogen bond?
300
This type of feedback loop stabilizes a systems, always correcting and balancing itself.
What is a negative feedback loop?
300
Encompasses all water on Earth - liquid, gas, ice, salt and fresh.
What is the hydrosphere?
400
This is a manner of using a resource so that it can be used at the same rate for the foreseeable future.
What is sustainable use? Or sustainably, sustainable, etc.
400
These types of papers are considered the most valid because they have been scrutinized by fellow scientists before being published.
What are peer-reviewed journals/papers?
400
Lipids, proteins, carbohydrates and nucleic acids are large biological polymers, also know as ....
What are biological macromolecules?
400
A thermostat is an example of this type of feedback loop.
What is a negative feedback loop?
400
The hard rock on and just below Earth's surface - the outermost layer of the geosphere.
What is the lithosphere?
500
This may occur when a resource is used freely by the public. Eventually all of the resource will be depleted and everyone loses access to it.
What is the Tragedy of the Commons?
500
Data that is expressed using numbers.
What is quantitative data?
500
A water molecule has an imbalance in its charge, making it this type of molecule.
What is a polar molecule?
500
Erosion is an example of this type of feedback loop.
What is a positive feedback loop?
500
Large chunks of lithosphere that are dragged along as the asthenosphere moves.
What are tectonic plates?
