Exam 1 Flashcards
What does geography mean?
From geo “earth” and graphic “to write”
What is spatial analysis?
The examination of spatial interactions, patterns, and variations over are and or/space.
What is systems theory?
Order, interrelated set of things and their attributes (flows of energy and matter)
What is a closed system?
Shut off from the surrounding environment
What is an open system?
Receive inputs and outputs from without
What is system feedback?
Outputs the influence operation;outputs function as information that returns to various points in the system via called feedback loops
What is system equilibrium?
Energy and material in a system that remains balanced over time
What is latitude?
Parallel lines, up and down on a globe
What is longitude?
Horizontal lines that go side to side
What is a map?
A generalized view of an area, as seen from above and reduced in size.
What is remote sensing?
Collection of information about an object from a distance through registering electromagnetic energy
What is GIS?
Geographical information system and they combine spatial and attribute data
What are inner planets?
Formed mostly of rock and metal(solid at high T)
Mercury, Venus,Earth, Mars
What are outer planets?
Are built of ice over rocky cores, massive and cool enough to hold thick layers of gas
Jupiter,Saturn,Uranus, and Neptune
What are the 3 things that define a planet?
Orbits sun
Spherical
Clears material and orbit
What is perihelion?
Earth’s closest position to sun
What is Aphelion?
Earth’s farthest position to sun
What is the plane of earth’s orbit?
Plane of eliptic
What is a cause sunspots?
Magnetic storms
What happens during a sunspot?
Explosions(solar flares)
Outbursts of gases
What is solar wind?
Clouds of electrically charged particles
Describe the earth’s magnetosphere
2 magnetic metals move past one another
Create magnetic field
Flow of the outer core around inner core creates this field
This protects us from radiation poisoning
What is insolation?
Incident solar radiation
What is the electromagnetic spectrums?
The spectrum which lets us view light but also has many other invisible energy Rays
What is seasonality?
Refers to seasonal variations of the sun’s position above the horizon and changing day lengths during the year
What’s the reason for seasonal changes?
Is the Suns altitude, where the sun is facing on the planet, the angle the sun is at
5 reasons for seasons
Revolution Rotation Tilt of Earth's Axis Axial parallelism Sphericity
What is revolution?
Earth revolves around the sun
What is rotation?
Earth rotates on axis once every 24 hours (day)
What is air?
Blended gases, odorless,colorless,tasteless,formless
What is the atmosphere made of?
Two regions which are Heterosphere and Homosphere
What makes up 90% of atmosphere’s mass?
Troposphere
