When a two continental plates push against each other it causes what to be formed ?
Mountains
Trenches
When a two plates move away from each other at a divergent boundary it causes sea floor to do what ?
Sea floor spreading
Sea floor shrinking
When a two plates slide past each other at a transform boundary is causes an
Earthquake
Sea floor shrinking
Where are most volcanoes located?
at divergent boundaries, transform boundaries, and hot spots
at convergent boundaries, divergent boundaries, and hot spots
at convergent boundaries, hot spots, and transform boundries
at divergent boundaries, convergent boundaries, and transform boundaries
This is a diagram of a soil triangle. Farmers can use this chart to identify the type of soil found on their land and determine the likelihood of erosion and other important factors. What type of soil does a farmer have if the coil contains 40% sand, 40% silt, and 20% clay?
clay
loam
silty loam
sandy loam
What would be most effective in minimizing the potential damage caused by an earthquake?
installing sirens in areas prone to earthquakes
building structures that withstand ground vibrations
increasing the amount of concrete during road building
requiring the recycling of metal and wood products
Bedrock that is closer to oceanic ridges is younger in age than bedrock that is farther away. What can best be concluded from this information?
The shape of Earth's lithosphere is continually changing.
The moment of continental plates is caused by volcanic eruptions
The oceans are becoming deeper and warmer as more rocks are produced.
The rocks on the ocean floor are producing tectonic plates that are converging
These rocks are often foliated, meaning they have layers.
Sedimantary
Sediment
Metamorphic
Igneous
