Which sphere of the Earth system includes trees, grasses, and squirrels?
Which is an example of a constructive force?
Which is a main source of energy that drives the Earth system?
The rocks that make up Earth are part of which sphere?
Through processes like erosion and weathering, ___________ forces destroy landmasses.
Heat flowing out of Earth as it cools is one form of ______________ that drives the Earth system.
Earth's core is mostly made up of iron and magnesium.
Scientists think that movements in the liquid inner core create Earth's magnetic field.
The oceanic crust is most like granite in composition overall.
Pressure and temperature increase as you move deeper below Earth's surface.
To learn about Earth's interior, geologists study how seismic waves move through Earth.
The core is Earth's outer skin of solid rock.
Which best describes the mantle?
Which lists the main layers of Earth in order from outermost to innermost?
How does heat move?
How is energy from the sun transferred?
Heat from which of these causes convection currents inside Earth?
Which of these combines with changes in a fluid's density and the force of gravity to set convection currents in motion?
When you touch hot sand, heat is transferred by conduction to your skin.
The Columbia Plateau is a landform that has high elevation and low relief.
High elevation and high relief describe the topography of a mountain.
A plain that is located away from the coast is known as an interior plain.
Three major types of landforms are plains, mountains, and plateaus.
An area's relief is the difference in elevation between its highest and lowest parts.
When you describe a landform's elevation, you describe its height above sea level.
What is the equator the starting line for measuring?
Which is a sphere that represents Earth's entire surface?
The equator divides Earth into the Northern Hemisphere and Southern Hemisphere.
A grid formed by lines of latitude and longitude can be used to find your location on Earth.
One half of the sphere that makes up the surface of Earth is known as a hemisphere.
The prime meridian is the starting line for measuring latitude.
V-shaped contour lines pointing uphill indicate a valley.
Index contours are darker and heavier than other contour lines.
The change in elevation from one contour line to the next is the contour interval.
Satellite maps include contour lines that show relief.
Mapmakers use contour lines to show elevation, relief, and slope.
Widely spaced contour lines indicate relatively flat areas.
A contour line connects points that have the same elevation.
