Question

Explain Attitude of an outcrop.

Answer 1

Outcrop Patterns. Geologic maps show where various rock units and structures lie at the earth's surface. Because many of these structures are planar, or approximately planar features, they interact with topography in predictable ways. Flat-lying Beds

Answer 2

Outcrop is exposure of rock beds on ground surface.

Explanation:

• Outcrop refers to the pattern of exposure of the rock beds on the surface of the ground.
• Geological maps show a variety of outcrop patterns.

• Outcrop pattern of strata is determined by two factors:

1. Dip and strike of a strata
2. The topography of the area

• Horizontal ground-On, horizontal ground the outcrops are always straight lines irrespective of the dip of the strata.

• Undulating ground-On undulating ground, the outcrop pattern varies with dip of strata.

1. Horizontal beds-Outcrop runs parallel to the contours.
2. Vertical beds-Outcrops are straight lines irrespective of the topography.
3. Inclined beds-The outcrops are curved and they cut across the contours.
