Weathering and Erosion
The process where rocks break down into smaller pieces is called this
Weathering
Tree roots growing into sidewalk cracks and breaking the concrete apart is an example of this type of weathering
Root Wedging
Active volcanoes and earthquakes often form a noticeable shape around the Pacific Ocean, commonly referred to as this
Ring of Fire
Basalt is a dark rock that forms after this erupts from a volcano
Lava
Landslides often occur on hills with very steep slopes after heavy amounts of this fall
Rain or Water
The process where rocks and soil are moved from one place to another by water, wind, or gravity is called this
Erosion
Water seeping into tiny cracks in rocks or pavement, freezing, expanding, and causing cracks is called this
Ice Wedging
The pattern of where active volcanoes occur around the world is closely linked to the pattern of these events
Earthquakes
Finding basalt rocks near a hill where there are no active volcanoes today suggests that there used to be one of these in the past
Volcano
One solution to reduce landslides is having town members pick up these off steep slopes
Loose Rocks
As rocks roll down a mountain, their edges become smoother and they break into smaller pieces. This evidence shows that rocks continue to do this as they move
Break down or Erode or Weather
Sidewalks in New Jersey have many more cracks than sidewalks in Florida mainly because New Jersey experiences cold winters with this
Snow and ice (or freezing temperatures/ice wedging)
On a global map, active volcanoes do not appear randomly; instead, they follow clear lines or these
Pattern
If you want to strengthen your claim that an ancient volcano existed in an area, finding more of this type of rock would serve as strong evidence
Basalt
Carving steps into a steep hillside helps reduce landslides by reducing the slope and doing this to falling rocks
Catching them
Rocks at the bottom of a smaller mountain are often less eroded than rocks at the bottom of a taller mountain because there is less of this for them to fall
Distance
Sidewalks in warm climates like Florida primarily experience this type of wedging rather than ice wedging
Root Wedging
If a country like Peru lies directly along a line of active earthquake and volcano activity on a map, a new volcano is likely or unlikely to pop up there?
Likely
Scientists use rocks as clues to learn about Earth's past environment, a field of study known as this science
Geology
Out of building a giant umbrella ($500,000), carving steps ($9,000), and picking up rocks ($700), this option is the most effective solution that fits within a $10,000 budget
Carving Steps (Solution 2)
True or False: Sharp, jagged edges on rocks are evidence that they have travelled a very long distance down a mountain
False (rocks with sharp edges have weathered less, while smooth, small rocks have travelled farther)
To gather scientific evidence comparing sidewalk cracks in two towns, students can count and do this to the cracks across multiple streets
Measure them
True or False: Earthquakes happen randomly all over the Earth without forming any kind of pattern
False
Finding multiple hills in an area that all have basalt rocks scattered around them indicates that the region experienced past volcanic activity across a wide or narrow area?
Wide
Landslides are especially dangerous on hills that have lots of loose rocks and this type of steep land feature
Steep slope
