Solar Energy
This movement of the earth causes day and night.
What is rotation?
97% of all water on earth is this non-drinkable type.
What is salt water?
These are seven large landmasses on earth.
What are continents?
This is molten rock, or magma, that reaches earth's surface.
What is lava?
This area between the Tropic of Cancer and the Tropic of Capricorn is located close the equator and defines its seasons by the amount of rainfall it receives throughout the year.
What is The Tropics?
This is the movement of earth as it travels around the sun.
What is revolution?
Most of earth's freshwater is trapped in these two places.
What are glaciers and underground?
This is the process of breaking down rock into smaller pieces called sediment and the most common cause of erosion.
What is weathering?
This theory suggests that the continents were once part of one big supercontinent.
What is continental drift?
This is a period of less than normal rainfall which causes dry conditions and can cause water shortages.
What is a drought?
This is the main thing that causes different seasons on earth.
This drives the water cycle.
What is solar energy?
Examples of these include mountains, valleys, plains, islands and peninsulas.
What are landforms?
This is the result of two continental plates colliding.
These are the two main processes of the water cycle.
Everything on earth derives its energy from this source.
What is the sun?
What is surface water?
This is an area around the perimeter of the Pacific Ocean where most of earth's volcanoes and earthquakes occur.
What is the Ring of Fire?
Occur when two plates slide past one another.
What are earthquakes?
The earth spins around this imaginary line.
When the northern hemisphere is having summer, the southern hemisphere is experiencing this season.
What is winter?
This type of water usually requires a well to access, is naturally filtered and good for drinking.
What is groundwater?
This theory states that earth's crust is made of pieces or plates that move by pulling apart, colliding together and sliding past one another.
What is plate tectonics?
Occurs where two ocean plates collide.
What are ocean trenches?
This measures the distance north or south of the equator.
What is latitude?
