Which statement best explains why Earth's lithosphere is broken into tectonic plates?

The brittle lithosphere cracks under pressure from the moving aesthenosphere.

Earthquakes form cracks in the lithosphere that grow larger over time, creating new plates.

Shortly after Earth formed, the lithosphere cooled, causing it to contract and crack.

The lithosphere cracks and deforms under the weight of the continents.

A geologist is studying the Fransiscan assemblage in northern California, a melange of sediments that originally formed in the ocean. How might this unit most likely have formed?

the accretion of rock on crust during a mountain-building event

Which kind of volcanism is most likely to occur at location A in the following map?

Location A is a hot spot in the oceanic crust, so it is likely to erupt lava with a high silica content, resulting in explosive volcanism.

Location A is mid-ocean ridge at a divergent boundary, so it is likely to erupt lava with a low silica content, resulting in relatively quiet volcanism.

Location A is a hot spot in the oceanic crust, so it is likely to erupt lava with a low silica content, resulting in relatively quiet volcanism.

Match your volcano type with the correct description.

Stavka koja se može prevući		Odgovarajuća stavka
Calderas		large, gently sloped volcanoes that result from the eruption of basaltic lava
Shield Volcanoes		large, steeply sided cones that form from alternating layers of pyroclastic material and lava flows.
Composite Volcanoes (Stratovolcanoes)		small, cone-shaped volcanoes that result from pyroclastic material that falls close to the volcanic vent.
Cinder Cone Volcanoes		Large, collapsed craters over a volcano's empty magma chamber and are formed after extremely explosive eruptions.
