Why do people live in tectonic areas 1.Why do people live near volcanoes? 2.What can be done to reduce the damage from a volcanic eruption?
EARTHQUAKES. Earthquakes & Plate Tectonics It is a vibration in the crust due to the release of stress Causes a shift in the rocks along a fault or plate.
What is a Barnacle? You may have seen barnacles along the shoreline attached to pilings or rocks.
EARTHQUAKES. What are Earthquakes? The shaking or trembling of the earth/ground caused by the sudden release of energy Usually associated with faulting.
GEOLOGIST! By: Tucker Roberts. What is their field of Science? The Earth! The Earth!
Location and Damage from EQ. Where EQ Occur Most EQ occur at plate boundaries More EQ occur at transform faults than at other plate boundaries Most.
Changes to Earth’s Surface Chapter 6. Prior Knowledge What are the layers of the Earth? What are the layers of the Earth? What causes Earth’s surface.
1.Tension – stretches rock, they become thin in the middle 2. Compression – pushes rock together, squeezes rock until it folds or breaks 3. Shearing –
This lesson will introduce some of the major kinds of landforms.
Earthquakes: vibrations through earth’s crust – Occur when rocks under stress slip or shift along a fault Normally, rocks are pressed together tightly.
