Our Changing Shoreline

  • Waves crash & Move Sand out to sea

  • Hurricanes & Tropical Storms

  • 15% of North Carolina's shoreline is critically eroding

Multiple Choice

How does the shoreline change?

1

Earthquakes are mostly to blame.

2

Waves crashing and pulling sand out to sea.

3

Animals move the sand when making homes.

6

Multiple Choice

Is beach erosion a problem for the North Carolina coastline?

1

YES!

2

No!

7

Landslides

  • Plant and tree roots help hold rock and dirt in place

  • Large amounts of rocks, mud, or other material slide down a steep slope

  • Erosion & Gravity can cause this

  • Rockfalls, Mudslides, and Avalanches are similar to landslides

Multiple Choice

Landslides cannot happen underwater?

1

True

2

False

Volcanos

  • Magma is melted rock under the Earth's crust

  • If magma breaks through the Earth, then it is called lava

  • Lava cools and creates a layer of rock which over time create the mountain

  • Magma travels up the vent & erupts out of the crater

Multiple Choice

The world's largest volcano is...

1

Stromboli (Italy)

2

Kilauea (Hawaii)

3

Mauna Loa (Hawaii)

14

Earthquakes

  • Earth's crust is made of many big pieces that fit together called plates

  • Faults are where the plates fit together

  • Faults are are different sizes

  • The San Andreas fault runs most of the length of California

  • Plates shift and create pressure, which causes the ground to move
