Identify the next step in this sequence of events that occurs in the formation of rock. buried , compacted, heated and___________

• buried

• recrystallized

• eroded

• deposited

What was Pangaea? When did it form and when did it break apart? It was

• a large, Precambrian shield area of Africa and South America that broke apart early in the Proterozoic

• a large ocean that opened in the Triassic and closed in the Paleocene

• the super continent that formed in the late Paleozoic and broke apart in Mesozoic

• the huge mountain range formed when Africa pushed northward into Europe in Eocene time

Convection in the upper mantle

magma injection at the spreading boundaries

gravity pulling the plates downward at subduction zones

These are three theorized causes of

• glacial melting

• high and low ocean tides

• movement of the tectonic plates

• changing of the climate

Fossils of a now extinct dinosaur have been found near the east coast of South America and the west coast of Africa. The dinosaur could not swim or fly. What does this suggest about the continents of South America and Africa?

• A land bridge once connected the continents

• Prehistoric man transported the dinosaur between the continents

• The continents were once connected

• The same type of animals evolved on both continents

The movement of the tectonic plates is caused by

• convection currents in Earth's mantle

• the gravity of the iron-nickle core

• the rotation of the earth

• the Moho discontinuity

Ocean trenches are formed when

• two oceanic plates grind past each other along transform faults

• two oceanic plates slide past each other

• an oceanic plate goes under another oceanic plate

• two oceanic plates hit each other causing both plates to rise up

1000 kg of limestone is subjected to intense heat and high pressure to form marble. All BUT one of the statements applies to the formation of the marble.

• Marble is a metamorphic rock

• About 1000 kg of marble is produced

• Marble is formed by recrystalization

• Marble is formed close to Earth's surface

Geologists have log recognized that earthquakes are not randomly distributed on Earth but occur in concentrated areas that coincide with_______and provide evidence for the theory of_____

• mountain ranges; fault zones

• plate boundaries; plate tectonics

• continental borders; supercontinents

• areas of liquid magma; sea floor spreading
