Comet
The process used to investigate what is happening around you.
Science
A prediction or statement that can be tested.
Hypothesis
_____________________ is gathering and analyzing information about an object without physical contact with the object.
Remote Sensing
When an obstacle causes wind to slow down and deposit materials, the materials pile up and eventually form a ___________________.
Dune
Moving of rocks or sediment.
Erosion
The application of science to make products or tools that people can use. A ballpoint pen is an example of this.
Technology
The variable that is changed. Can only change one of these types of variables.
Independent
A system of satellites from which position on Earth can be determined.
Global Positioning System
Landslides and rockfalls are examples of erosion and deposition by which agent of erosion?
Gravity
Dumping of rocks or sediment.
Deposition
Used to answer scientific questions by testing a hypothesis through the use of a series of controlled steps.
Scientific Method
The factor(s) being measured.
Dependent
The fan shaped mass of sediment deposited by a stream into an ocean or a lake is called.
Delta
Which of the following agents is most likely responsible for the formation of the sand dunes?
Wind
Breaking of rocks or sediment.
Weathering
A ______________________________ is an explanation for how something occurs. It is supported by a great deal of evidence.
Theory
Variables that stay the same.
Constants
_______________ is the process by which sediment and other materials are moved from one place to another.
Erosion
Which landform listed is mainly formed because of erosion by groundwater?
sink hole
What is a factor in a stream's ability to erode material?
Load, gradient, or discharge
A basic principle that applies everywhere and in all situations is the best described as a scientific ____________.
Law
Which type of map would be the most useful to study the shape and size of an erosional land feature?
Topographic
Large masses of flowing ice called _______________ are typically found near Earth's poles and in other cold regions.
Glaciers
In places where there is loose sediment and strong wind, the wind can pick up the sediment and carry it. When the wind slows, it deposits the sediment. Which type of sediment will be dropped first as the wind slows?
heaviest
An experiment is completed by a different person and gets the same results.
