Earth Science Chapter 7

The balance of the weights of the rocky materials, water, and ice in and on the earth's crust against the upward push of the mantle is called

• orogeny

• tectonics

• topography

• isostasy

The topography of a region is

• a line of elevation of the region on a map.

• the differences of land elevations in that region.

• the kinds of colors used on a landform map of the region.

• the balance of forces between the crust and the mantle in that region.

Elevation is the height of a mountain's peak above __________.

• the deepest ocean trench

• the region's relief

• its base

• mean sea level

The study of mountain-building processes is called __________.

anticlines and synclines belong to

• fold mountains

• depositional mountains

• basins

• fault-block mountains

What is the major difference between a fault and a joint?

• Faults are always bigger than joints.

• Faults occur on land while joints are found beneath the ocean.

• Faults involve visible movement of rocks but joints do not.

• Faults cannot cause earthquakes but joints can.

The Modified Mercalli Intensity scale measures earthquake's

• wave speed

• wave duration

• damage

• magnitude
