Sol Earth Science Practice

When the sea floor spreads apart, volcanoes and ridges are formed because —

• sediments are deposited where the floor spreads, building ridges

• as the plates pull apart, magma moves to the surface, building ridges

• ocean water pushes down on the surrounding sea floor, pushing up ridges

• underwater earthquakes lift the sea floor into long ridges

Even though the Earth’s inner core is hotter than the liquid outer core, it is still solid because —

• the heat rising from the inner core is melting the outer core

• there is more water in the outer core and it dilutes the materials

• the outer core is farther from the center, and there is less gravity holding it together

• the pressure from all of Earth’s layers keeps it in a solid state

All of the following support the theory of continental drift except that —

• the continents seem to fit together like pieces of a puzzle

• there are similar fossils on different continents

• mountain ranges in South America and Africa line up

• the North Pole and Antarctica are covered with ice

The mountain shown is composed of deformed sedimentary layers. They are located near a tectonic plate boundary and are still increasing in elevation due to —

• colliding tectonic plates

• seafloor spreading of tectonic plates

• subduction of a tectonic plate

• transform faulting of a tectonic plate

Which provides the best evidence for the theory that faults and volcanoes are results of tectonic plate interactions?

• Faults on tectonic plates are in constant motion, but volcanoes may not erupt for many years.

• Faults and volcanoes existed long before there were tectonic plates.

• Tectonic plates that have many faults do not usually have volcanoes.

• Faults and volcanoes are often found at tectonic plate boundaries.

Geologists think that parts of the Appalachian Mountains formed originally from sediments accumulating in shallow swamps. The weight of the sediments caused the area beneath them to sink, allowing more sediments to accumulate. The process continued until many layers had formed. Then tectonic processes folded the layered sediments into a range of mountains. What evidence for this theory can be found in the current structure of these mountains?

• Some rocks making up these mountains show signs of volcanism.

• The form of these mountains is very eroded.

• The mountains exhibit folded layers of rocks containing fossils from shallow water.

• The mountain range consists of parallel ridges of different ages.
