Natural Resources
Examples of nonrenewable resources
What are rock, minerals, metals, uranium, and fossil fuels such as coal, petroleum, and natural gases?
The curved lines in a topographic map that represent a specific elevation
What are contour lines?
The Old Man of the Mountain a good example of physical weathering because of this reason.
What is because freezing and thawing over many years caused the formation to collapse
The carrying away of weathered earth materials by forces such as water, wind, and ice.
What is erosion?
True or false:
Water turns into a solid when it freezes.
What is true?
Resources that cannot be used up or it is one that can be replaced.
What are renewable resources?
The change in elevation between any two contour lines.
What are contour intervals?
Earthquakes, volcanoes, tsunamis and landslides are examples of this
What are rapid landform changes?
The process when the sediments are deposited, or dropped off, in a different location.
What is deposition?
True or false:
Deposition can change the way the surface of the earth looks over time.
What is true?
Natural resources that cannot be replaced after they are used.
What is a nonrenewable resource?
A map that uses contour lines to show the shape and elevation of the land.
What is a topographic map?
This volcano erupted because an earthquake happened, shaking it and causing a large avalanche of debris to slide down the side of the volcano.
What is Mount St. Helens?
The process that breaks rocks apart by breaking and banging.
What is a physical weathering?
True or false:
When Mount St. Helens erupted it did not cause any damage.
What is false. The eruption killed 57 people, over 12 million fish, and 7,000 animals. The eruption destroyed 200 homes, 27 bridges, highways and railways.
Examples of renewable resources
What are air, water, soil, plants, and animals?
Where you find contour intervals on a map
What is a map key?
How can science help with natural disasters, like volcanic eruptions or earthquakes?
What is scientists continue to monitor mountains like Mount St. Helens to learn more about volcanoes and to warn people if they think another eruption is about to happen.
A vertical section cutting through the soil showing the different layers of the soil.
What is a soil profile?
True or false:
Examples of fossil fuels are petroleum, coal, and natural gas.
What is true?
examples of renewable resources that help us to produce energy without burning fossil fuels
What are wind, water, and sun?
How would you use a topographic map to go hiking?
What is to plan routes, estimate travel times, find water, good campsites, and track their progress on hikes?
What is the effect of slope on erosion and water movement?
What is the steeper and longer a slope is, the faster water runs off of it, and the greater potential there is for erosion.
This is caused by the effects of changing temperature on rocks, causing the rock to break apart.
What is physical weathering?
True or false:
The profile of Mount St. Helens did NOT change after the eruption in 1980.
What is false. After the eruption in 1980, the summit of Mount St. Helens was gone, forests were obliterated and rivers followed new courses. More than 150 new lakes and ponds were formed.
