Explanation:
Answer:
1. horizontal
2. vertical
3. inclined
Explanation:
The strata are defined as the layers of various rocks. It may be sedimentary rocks, igneous rocks, etc. The orientation of the strata determines the position of the rock layers or the altitude of the rocks in the three dimensional spaces in the earth's crust.
In the context,
The outcrop pattern of the horizontal strata are cut by the stream canyons that are parallel to the canyon walls. And the outcrop pattern of the vertical strata are cut by the stream canyon that makes an apparent straight line that crosses the canyon.
While the pattern of the inclined strata that are cut by the stream canyon which makes the apparent V shape and is pointing in dip direction.
This is because as per the rules of the V's, the inclined beds or the dipping are incised with the streams or valleys or canyons, it makes a "V" in dip direction. But when the strata have a vertical dip, then it does not make a "V". And when the beds are horizontal, it will be parallel and will follow the contours.
