Earth Science
This branch of Earth science studies objects beyond Earth's atmosphere.
What is astronomy?
Passive remote sensing uses sensors that detect natural radiation reflected by surfaces.
What are sensors that detect natural radiation reflected by surfaces?
This system is used for capturing, storing, and displaying location-based data.
What is a Geographic Information System (GIS)?
This measurement specifies a location's distance north or south of the Equator.
What is latitude?
This term describes the mixture of gases that surrounds Earth and makes life possible.
What is the atmosphere?
This field is NOT considered a major branch of Earth science.
What is astrology?
This remote-sensing instrument emits its own signals and measures the reflections, making it an example of active remote sensing.
What is a radar altimeter?
Combining layers of population density, land use and flood risk to plan evacuation routes is an example of how this technology is used.
What is GIS?
This imaginary line circles Earth halfway between the poles and is at 0° latitude.
What is the Equator?
This branch of Earth science studies the atmosphere and weather.
What is meteorology?
The study of Earth's oceans and marine processes is this branch of Earth science.
What is oceanography?
This technology is used to detect objects underwater by sending out sound waves and measuring the echoes.
What is sonar?
On a topographic map, lines connecting points of equal elevation are called these.
What are contour lines?
This imaginary line at 0° longitude divides Earth into Eastern and Western Hemispheres.
What is the Prime Meridian?
This layer of Earth's atmosphere is where weather occurs and contains most of the atmosphere's mass.
What is the troposphere?
All water on Earth—including oceans, rivers, ice, and groundwater—is part of this Earth system.
What is the hydrosphere?
This positioning technology determines a receiver's location by using signals from multiple satellites and calculating its distance from each one.
What is using signals from multiple satellites to calculate the receiver's distance from each satellite?
What does the acronym GIS stand for?
What is Geographic Information System?
When writing geographic coordinates, this is listed before longitude.
What is latitude?
This gas makes up about 78% of Earth's atmosphere.
What is nitrogen?
Approximately what percentage of Earth's water is saltwater?
What is 97 percent?
Remote sensing is important in cartography because it collects current, detailed information about Earth's surface without physical contact.
What is collecting current, detailed information about Earth's surface without physical contact?
This technology allows users to overlay and analyze multiple layers of geospatial data to reveal patterns and relationships.
What is a key benefit of GIS?
On the blank map provided: draw and label the Equator (0° latitude) and the Prime Meridian (0° longitude), add at least two lines of latitude north or south of the Equator, and add at least two lines of longitude east or west of the Prime Meridian.
Draw and label the Equator, Prime Meridian, and at least two latitude lines and two longitude lines with correct terminology.
This atmospheric layer contains the ozone layer that absorbs harmful ultraviolet radiation from the Sun.
What is the stratosphere?
