#### the angle of an object measured in a direction other than parallel to the strike

Correct! Wrong!

The apparent dip of a geological plane is the angle of inclination that it seems to have when measured in a direction other than parallel to the strike.
When you can't measure the dip angle directly along the strike direction, you can estimate it in this fashion.

#### the inclination of an inclined plane measured perpendicular to its maximum slope

Correct! Wrong!

When measured perpendicular to a geological plane's highest slope or the direction of steepest descent, such as a rock layer or fault, dip is the angle at which the plane is inclined.
To put it another way, it shows how sharply the plane deviates from the horizontal plane.

#### A horizontal line's bearing on an inclined plane

Correct! Wrong!

The angle between a geological plane and the horizontal plane, such as a rock layer or fault, is referred to as inclination.
The inclination angle tells us how steeply the inclined plane is inclined with respect to the horizontal when a horizontal line meets it.
It is a measurement of the inclined plane's slope or tilt.

#### the orientation of the line-containing vertical plane.

Correct! Wrong!

Geologists use the term "trend" to describe the compass direction that a linear geological feature extends along on the horizontal plane.
It's a crucial idea for explaining how rock strata, faults, and other geological structures are arranged spatially.

#### the horizontal angle between a given coordinate direction (usually north or south) and a certain time

Correct! Wrong!

The term "bearing" describes the horizontal angle, expressed in degrees clockwise, between a reference direction (often North) and a particular point or direction.
It frequently provides directional information in navigation, surveying, and other applications.

#### A horizontal line's bearing on an inclined plane

Correct! Wrong!

Understanding the orientation of geological features depends on knowing the strike of a geological plane, which provides the compass direction of a horizontal line on the plane's surface.
It is not affected by the plane's inclination and is measured in degrees clockwise from North.

#### the slope's slope angle from the horizontal

Correct! Wrong!

The slope angle, which indicates how steeply a geological feature is sloped in relation to a flat surface, is the angle at which the feature is inclined with respect to the horizontal plane.
