Pregunta 1
Pregunta
Facts about Earthquakes: Within the earth, there is tremendous heat as much as 1500 degrees fahrenheit. Heat rises and tries to escape between and through the plates. Consequently, the plates may be displaced and/or ruptured.
Respuesta
- True
- False
Pregunta 2
Pregunta
An earthquake can:
Respuesta
-
Make buildings split and crumble or fall into large cracks.
-
Destroy roads, railroad tracks, and bridges. Telephone poles and electric lines are ruined.
-
Change the course of rivers and streams. Mountains may have avalanches or be split and leveled, and flat land can become lumpy and even hilly or mountainous.
-
Break water pipes, cause flooding.
-
All of the above.
-
None of the above.
Pregunta 3
Pregunta
Many earthquakes take place on ocean bottoms.
Respuesta
- True
- False
Pregunta 4
Pregunta
Describe how tectonic plates work.
Respuesta
-
They collide with one another and squish into big slabs of rock.
-
They are able to float due to the age of rocks. Since there are great variations in plate ages it can compensate for the length and weight of the crust, and since continental rocks are much heavier the much thicker crust below can hold it.
-
They are able to float due to the composition of rocks. Since there are great variations in plate thickness it can compensate for the weight and density of the crust, and since continental rocks are much lighter the much thicker crust below can support it better.
-
They are able to float because of the layout. The variations in where the plates lie allows them to move around freely and occasionally they will collide.
-
All of the above.
-
None of the above.

-
All of the above.
Pregunta 18
Pregunta
[blank_start]___[blank_end] occurs when new layers of sediment are deposited on top of older layers and the weight squeezes out any spaces between particles that make up the lower layers, flattening the particles and causing them to interlock. [blank_start]______[blank_end] occurs when minerals, dissolved in water, filter through the sediment and act as cement grains together to form sedimentary rock.
