Revolution one year for the Earth to orbit the sun, or to complete one revolution.
365 1/4 days
Rotation- One complete spin on Earth’s axis is called a rotation. Each rotation takes
24 hours= 1 day
3. What are the five themes of geography? Describe each.
Location-is the position of a place on Earth’s surface
Place- describes the physical and human characteristics that make a location unique
human environment interaction- How people affect their environment and how their
environment affects them.
Movement- explains how and why people and things move and how they are connected.
Regions- Areas that share common characteristics
4. What is the difference between relative and absolute location?
Absolute location: is the exact spot on Earth where something is located Ex- 45°N 15° E
Relative location: describes where a feature is in relation to the features around it
5. How many continents are there? Name them.
7 continents- Asia, Africa, Europe, Australia, Antarctica, North America, South America
6. What causes the seasons on Earth?

Vertical Lines, run from north pole to south pole, EAST & WEST Of the Prime Meridian
9. What does a political map show? What does a historical map show? What does a physical map show?
Outlines of countries, historical movement or how things have changed, the earth’s surface
and physical features
10. How do tectonic plates cause earthquakes? What happens when continental and oceanic plates
collide?
When two tectonic plates collide and create sudden and violent movements of the earth’s
crust
the oceanic plate tips down and slides beneath the continental plate forming a deep
ocean trench.

of Cancer
June 21- summer solstice longest day of year
13. Describe what occurs between the Earth and Sun on our Winter Solstice. When does the Winter
Solstice typically occur?
Day when the sun’s rays are farthest from the equator, they hit most directly on the
tropic of Capricorn. December 22- shortest day of year

The Equator

distributaries
21. What is the difference between weather and climate?
Weather is the day to day variations of temperature, climate is the weather over a
long period of time
22. List and describe the steps of the water cycle.
Precipitation: Droplets become heavy and fall back down to Earth in form of rain, hail, sleet, or snow
Evaporation: Sun heats surface water, which evaporates into the atmosphere
Condensation: Water vapor cools as it rises and forms liquid droplets, which forms clouds
