The Himalayan Mountains are depicted on the map. The Himalayan Mountains were created from ancient seabeds that were lifted up by —

• volcanic activity in China's southern plateau.

• a reversal in Earth's magnetic field.

• a collision between the Indo-Australian plate and the Indian Ocean.

• a collision between the Indo-Australian and Eurasian plates.

Geologists who study past life forms are called paleontologists. They have contributed to the development of the theory of plate tectonics by recovering fossils that suggest continental drift occurred. The relevant fossils belong to organisms that lived —

• far apart and had similar shapes and genetic patterns.

• close together and had different shapes and genetic patterns.

• at different times and did not have similar shapes or genetic patterns.

• in the same area and had different shapes and genetic patterns.

In 1925, Germany sent a ship on a two-year trip to examine the world's oceans. The expedition found a continuous ridge running through the Atlantic to southwestern Africa. Later, it was discovered that the ridge extended through all of the world's major oceans. Through this underwater range ran a deep canyon, called the Great Global Rift. In places it came very close to land, outlining chunks of Earth's crust. What did the presence of the rift indicate to geologists?

• Seafloor spreading occurs mostly in the Atlantic.

• The rift marked the boundaries between tectonic plates.

• The world's oceans are all interconnected.

• Land masses close to the rift could be at risk of volcanic eruptions.

The map shows evidence of mountains that formed at the same time and in the same way in different parts of the world. Which of the following is not supported by this information?

• The theory of natural selection

The image shows the formation of a mountain range from interactions at plate boundaries. Type in the plate boundary that is MOST LIKELY responsible for the formation of the mountain range in the image.

A __________ plate boundary formed the mountain range.

Which features form at plate tectonic boundaries?

Pick THREE correct choices.

• A ridge can form when two plates move apart.

• A mountain range can form when two plates collide.

• A valley can form when two plates are pushed upward.

• New crust can form when two plates slide past each other.

• A trench can form when one plate moves beneath another.

The picture below shows an erupting volcano.
This volcano could have formed and erupted when —

• less dense oceanic crust was forced under denser continental crust, causing the oceanic crust to heat up, melt, and flow upward to relieve pressure.

• denser oceanic crust was forced under less dense continental crust, causing the continental crust to heat up, melt, and flow upward to relieve pressure.

• two equally dense tectonic plates collided and both pushed upward, causing friction that heated up minerals between the two rising plates.

• two equally dense tectonic plates separated and allowed hot minerals from Earth's crust to flow upward and out of the opening that formed between the two plates.

The multi-directional movement of tectonic plates causes many geological events such as volcanoes, earthquakes, mountain building, and the formation of new ocean basins. The source of this movement that causes these events is —

• convection currents created by heat from radioactive decay inside Earth.

• excess heat from the Sun that melts the crust to form lava and magma which move over the plates.

• Earth's rotation on its axis, which forces the plates to move across the Earth's surface.

• the gravitational force of the Sun pulling on Earth's crust.
