Earth Science Part 2 : Monitoring/Controlling Earth's Changes

Citizens of Tybee Island noticed the shoreline at their local beach was quickly eroding away each day. Which process would help replenish the shoreline?

• contour plowing

• terrace farming

• beach nourishment/reclamation

• sea turtles

Pumping/digging up sand from the bottom of the ocean floor to pump back on eroded beaches is called………

• beach digging

• sand dredging

• sand pumping

• ocean floor removal

Weather forecasting techniques have advanced thanks to technology.

Using satellite infrared imagery gives meteorologists the ability to…..

• Make storms change their course

• Stop storms from happening

• Predict where/when storms are likely to hit

• Change the weather

Farmers plants trees around their fields to serve as wind breaks – this helps keep soil and plants in place. What could happen if the wind breaks were removed?

• The soil would be healthier

• There would be less soil and plants in the field

• Nothing would change

• There would be less soil but the same amount of plants

Dams are built across rivers to…….

• Control the flow of the river water/water levels

• Stop the downstream flow of the river

• Change the direction the river is flowing

• Evaporate the water in the river

A storm surge occurs when a large wave is brought to the shore by a hurricane – sand dunes act as a barrier to keep the ocean waves from reaching buildings.

 What is one way we can improve sand dunes to be better prepared for future storm surges?

• Get rid of wind fences used to build up the dunes

• Quickly rebuild any buildings damaged by storm surges

• Plant more vegetation (trees & plants) in & around sand dunes

• Leave more space between buildings

Farming in areas with rolling hills can be difficult - in these areas, farmers plow the land in curves instead of straight lines. This method is called contour plowing.

Why is this helpful?

• It is pleasing to the eye/crops look pretty

• Lowers the number of bugs that damage crops

• Prevents the loss of topsoil due to erosion

• It is a safer method of farming
