Science
What is the process in which rock, soil, or sand breaks down and wears away?
erosion
What has the most impact on the rock layers of the Grand Canyon?
The river
What is the relationship between where earthquakes and volcanoes occur?
They both mostly occur on the edge of continents
How can you show an example of how hurricanes changes the coastal land?
A. Pour water over sand in a cup.
B. Pour water over a plastic toy.
C. Pour water into a blue-colored glass.
D. Pour water into the sink.
A. Pour water over sand
Flash floods and large waves are considered _____ because they result from natural processes involving water.
Physical Resources, hazards, outcrops, or erosion
hazards
What can cause rock layers to be present at different levels in the ground?
an earthquake causing the ground to shift
on continents along the coast
What is the Ring of Fire?
an area that has 75% of the world's volcanoes; it also has ocean trenches found along the edges of the land features
Explain the process of erosion in a flowing river.
The water in the river moves rocks and dirt, causing the land to wash away
What is an example of how rainfall can shape the land?
A. Place an ice cube on a baking sheet, and set it in the sun until it melts.
B. Pour water on top of a pile of sand, and watch as it moves the sand around.
C. Place a fan in front of a pile of sand, turn it on, and watch the sand blow away.
D. Set a large rock in a tray of water, and watch as the rock weathers by the next day.
B. Pouring water on top of a pile of sand and watching as it moves the sand around
If you live somewhere that is experiencing more erosion due to an increase in rain, what can you do to stop it?
consider ways to slow down the erosion
Termites build large mounds out of soil by moving soil from one area to another. How can this affect the environment?
The termites remove existing soil from areas causing damage to plants and homes
How can the river in the Grand Canyon change the valley over time?
The water makes the valley deeper by breaking away the sides of the bank.
What can break down rocks and erode things in the environment? BONUS if you can name four.
wind, water, ice, and plants
Scientists predict an earthquake will occur in the middle of the ocean. Why is it important to warn the nearest coastal town, even if it is over 300 miles away from where the earthquake occurs?
Earthquakes in the ocean can cause large waves that could flood the coastal town even 300 miles away.
Explain what can cause changes in rock layers.
Earthquakes can make types of rocks be present in different areas.
What can slow down the amount of land loss along the coastline?
Increasing the amount of plants and trees growing in marshes and swamps that make-up the coastline
Give an example of an improvement that can cause people to be better protected from natural hazards
a device that provides data on possible flooding
Engineers are designing a sea wall to protect a seaside town. The purpose of the sea wall is to prevent the ocean waves from causing erosion. The wall will be built into the ground and will stand up out of the sand. How could you use a model to test what needs to be improved?
Place the model into a pool and make waves to test at which height the sea wall no longer protects the coast from the waves.
Explain the importance of using models to explain hurricane patterns and how models can better assist us in analyzing the effects of storm surge on our coastline.
1. It can help humans prepare for the intensity of the hurricane.
2. They can be better prepared for the future and understand how to prevent erosion so that the land is preserved.
