What most likely caused the rock to change?
Water seeped into the rock and froze, causing the rock to break farther apart. This occurred many times.

What type of erosion is causing the Louisiana coastline to disappear?
Water erosion/Coastal erosion
100
Natural event that has the POTENTIAL to damage or destroy property, as well as take lives
What is a natural hazard?
100
Shaking of the ground caused by friction between tectonic plates?
Earthquake

What U.S. region is Louisiana located in?
Southeast

What is the effect of a plant growing in a rock?
The plants roots and structure will grow and extend causing the rock to break and erode away at parts.

How can people reduce the effect Earthquakes have on buildings?
Build buildings that are designed to move with the Earth.

The Appalachian Mountains are in what two U.S. regions?
Northeast and the Southeast
300
How are canyons formed?
A moving body of water erodes the sides and bottom of land. Sediment being carried knocks into rocks causing them to break and be pushed downstream.

What is one effect of climate change?
Answers vary:
Carbon dioxide is being put into the air.
The glaciers are melting.
Sea levels are rising, causing coastal towns to be flooded more often.
Severe weather and Natural Hazards/Disasters occur more often

What is one solution to keeping a volcanic eruption from turning into a disaster?
Answers vary:
Evacuating people out of the danger zone
300

How are desert rocks shaped by wind?
Wind picks up the desert sand and carries it until it hits more rocks/sand. When the sand hits the rocks/sand it is broken up into even smaller sand particles.

What most likely caused the bank to change?
Water eroding the cliff over time.

How does the nutria rat affect coastal erosion?
The nutria rat burrows (digs) in the ground and chews up plant roots, causing the soil around the roots to erode away.

Building walls, putting up nets for falling rocks, and planting trees are ways to prevent this natural hazard.
Landslide

If I wanted to know if the speed of water affects how land changes, would I:
Pour the same amount of water on two hills. One for 30 seconds, the other for 60 seconds.
Or
Pour different amount of water on two hills, both timed for 30 seconds.
Pour the same amount of water on two hills. The 30 second hill will have water poured on it quicker than the 60 second hill. The test is valid because both hills are using the same volume of water. In an experiment you can only test one thing (variable) at a time.

How did the river change the valley over time?
Water and sediment eroded the sides of the river allowing it to slowly widen over time. The soil along the river became loose and wore away.

What are 2 solutions for how to prevent climate change?
Answers vary:
Ride bikes/walk to school instead of driving cars
Use Clean energy
Watch your water use

Map 1 shows where volcanoes are in North and South America. Map 2 shows the location of Earthquakes in the U.S.
What part of the U.S. do most of the Earthquakes occur?
The west coast

Large slide of snow,ice, and/or earth down a slope
Avalanche

Plant seeds begun growing in this rock. Why did the rock crack?
The plant seed roots began to grow and applied pressure to the rock. After a while the roots put enough pressure on the rock that it cracked.
