    Define crustal deformation and explain the three types of stress that cause it.

    <p>Crustal deformation refers to the changing of the Earth's crust due to tectonic forces. The three types of stress that cause crustal deformation are compression, which causes folding; tension, which causes thinning; and shear, which causes one type of faults.</p> Signup and view all the answers

    What is the concept of strike and dip, and how is it used in describing the orientation of deformed rock layers?

    <p>The concept of strike and dip is used to describe the orientation of deformed rock layers. Strike refers to the direction of the line formed by the intersection of a horizontal plane with the surface of the inclined strata, and dip is a measure of the maximum angular deviation of an inclined plane from horizontal, measured perpendicular to the strike direction.</p> Signup and view all the answers

    How are strike and dip indicated on geologic maps?

    <p>Geologic maps indicate strike and dip by using a long line oriented in the strike direction and a short line perpendicular to the strike line, pointing in the dip direction. The number adjacent to the strike and dip symbol indicates the dip angle.</p> Signup and view all the answers

    What is the process of determining the strike and dip azimuths and compass quadrant bearings?

    <p>To determine the strike and dip azimuths and compass quadrant bearings, the angle made by the green arrow with 0° is measured to obtain its azimuth. The azimuth and compass quadrant bearings are used to indicate the direction of the strike.</p> Signup and view all the answers

    How are sediments deposited according to the principle of original horizontality, and what type of rocks form horizontal or nearly horizontal layers?

    <p>According to the principle of original horizontality, sediments are deposited in horizontal layers. Sedimentary and some igneous rocks, especially many lava flows, form horizontal or nearly horizontal layers.</p> Signup and view all the answers
