• continents

• core

• lithosphere

Which statement about the Earth's crusts is CORRECT?

You are part of a disaster response team sent to a region recently affected by a major earthquake. Local communities are asking why the ground shifted so violently. Which of the following best describes the continuously moving part of the Earth's crust responsible for this event?

• fault

• fissure

• fracture

• plate

Scientists have observed that earthquakes, volcanic eruptions, and mountain formation are all linked to movements in the Earth's crust. Based on these observations, which theory best explains how the Earth's crust is broken into sections that are constantly shifting?

• Continental Drift

• Plate Tectonics

• Seafloor Spreading

• Titanic Theory

Different types of plate boundaries produce distinct geological features and processes. At a convergent plate boundary, two tectonic plates move toward each other. Based on this interaction, which of the following outcomes is most likely to occur?

• new crust is created

• the older crust is melted by subduction

• the crust separates

• plates side past one another

Plates slipping past each other at ________________.

• subduction zone

• convection current

• divergent boundary

• transform boundary

The boundary between two plates moving together is called a __________.

• divergent boundary

• transform boundary

• lithosphere

• convergent boundary

At the convergent plate boundary, _______________.

• new crust is created

• the crust separates

• the older crust is melted by subduction

• plates side past one another

The Himalayan Mountain range of India was formed at the __________.

• divergent boundary

• convergent boundary

• hot spot

• transform boundary
