Earth's Features
This term is what lava is called when it is still under earth's crust.
What is Magma?
About this percent of Earth’s surface is covered by water.
What is 71%?
The process that breaks rocks into smaller pieces over time.
What is weathering?
The sphere that includes rocks, soil, and landforms.
What is the Geosphere?
When water overruns normally dry land, this event occurs.
What is a flood?
These animal remains on multiple continents support plate movement.
What are Fossils?
This percentage of Earth’s water is saltwater.
What is 97%?
This can get inside rocks to break them apart from the inside.
What is water, freezes, becomes ice, expands?
The sphere that includes all water on Earth.
What is the hydrosphere?
These fast-forming floods sweep away objects in their path.
What is a flash flood?
This Pacific “Ring” marks high volcano and earthquake activity.
What is the Ring of Fire?
Name one of the three main sources of usable freshwater.
What are Groundwater, running water (rivers/streams), or standing water (lakes)?
Oxygen bonding with iron in a process called oxidation creates this.
What is rust?
Dead plants and animals forming fossils, coal, and oil shows interaction between these two spheres.
What are the biosphere and geosphere?
A series of large waves caused by abrupt ocean-floor movement.
What is a tsunami?
When plates on the ocean floor collide this can happen.
What is a Tsunami?
Saltwater differs from freshwater mainly because of this property related to “heaviness.”
What is salinity?
Wind or water carrying particles that scrape rock surfaces.
What are Erosion/Abrasion?
Air temperature affecting evaporation links these two spheres.
What are the atmosphere and hydrosphere?
This instrument records ground shaking from earthquakes.
What is a seismometer?
This theory explains continents once fit together like puzzle pieces.
What is Plate Tectonics?
Human actions can harm water quality even from far away through this process of rain and runoff carrying pollutants.
What are water runoff and pollution?
The dropping of sediments by wind, water, ice, or gravity.
What is deposition?
Water eroding land and delivering nutrients to lakes connects these spheres.
What are the hydrosphere and geosphere?
Humans cannot prevent natural disasters but they can.
What is prevent/reduce impact?
