Answer: Unconformity is the procedure between two rocks having a contact. It is usually observed that upper unit of rock is younger in nature compared to the lower unit of rock.
Explanation: There are different types of unconformities such as:
- Disconformities- it is a uncoformity which has a parallel nature along with the rocks in the sedimentary form during the phase of erosion
- Non-conformities - it is a unconformity that creates the separation between the sedimentary rocks and other rocks like igneous rocks. They usually display the erosion that has occurred long time back.
- Angular unconformities-it is also a type of separation that is present between the younger rocks and the older rocks units.
The slope of segment CD is 7. The length of segment BC is √50 units and the figure is a square.
Explanation:
Part A
Slope of a segment is calculated as the ratio of rise over run
In this case, C (8,3) and D(7,-4)
The slope is m=Δy/Δx
Δy=-4-3=-7
Δx=7-8=-1
m= -7/-1 =7
The slope is positive as seen in the graph for segment CD
Part B
To find length of a segment, the formula to apply is:

Given that B(3,8) and C(8,3) then
x₁=3,x₂=8,y₁=8,y₂=3
substitute values in equation as;

The formula used to find length of a segment
Part C
The geometric figure is a Square.The proof is that the length of the segments is equal, √50 units

Lines of latitude are horizontal. They meet at itself.
Answer:
x = 15
Explanation:
As we can see it is an isosceles triangle so
The perpendicular line joining the vertex and base of isosceles triangle bisects the base. so
Taking the triangle of right side
hypotenuse (h) = 25 inches
base (b) = 20 inches
perpendicular (p) = x = ?
We know by using Pythagoras theorem
p= √h² - b²
x = √ 25² - 20²
= √ 225
x =15
Hope it will help :)
