Earth’s Spheres
The layer of gases surrounding Earth.
What is the Atmosphere?
Rain nourishes the soil, helping plants grow. Which two spheres are interacting?
What are the Hydrosphere and Biosphere?
The shape of the land is called this.
What is Topography?
A tall landform with high elevation.
What is a Mountain?
A map that shows surface features as if viewed from above.
What is a Topographic Map?
All the frozen parts of water on Earth.
What is the Cryosphere?
Volcanic eruptions release gases and ash. Which spheres are interacting?
What are the Geosphere and Atmosphere?
The height above sea level.
What is Elevation?
A landform created where a river meets the ocean.
What is a Delta?
Lines on a topographic map that show elevation, relief, and slope.
What are Contour Lines?
Earth’s solid parts, such as rocks, soil, and landforms.
What is the Geosphere?
Ocean waves erode coastlines. Which spheres are interacting?
What are the Hydrosphere and Geosphere?
The difference between the highest and lowest points of an area.
What is Relief?
Name one constructive force that builds up land.
What is mountain formation (or volcanic activity)?
Closely spaced contour lines mean this about the land.
What is Steep Land (or slope)?
Which sphere contains plants, animals, and people?
What is the Biosphere?
The sun’s energy heats water, turning it into vapor. Which spheres are interacting?
What are the Hydrosphere and Atmosphere?
Steep and flat areas can be compared using this measurement.
What is Relief?
Name one destructive force that wears down land.
What is rain, wind, ice, or fire?
Widely spaced contour lines mean this about the land.
What is Flat Land (or gentle slope)?
Which two spheres together include clouds?
What are the Atmosphere and Hydrosphere?
An earthquake destroys habitats. Which THREE spheres COULD be interacting?
What are the Geosphere, Biosphere, and Atmosphere (if dust/ash is released)?
A valley with an elevation of 200 m lies next to a hilltop of 650 m. What is the relief of the area?
What is 450 m?
Land along the edge of an ocean or sea.
What is a Coastline?
The two main features topographic maps use contour lines to show.
What are Elevation and Relief (or slope)?
