CD is perpendicular to AB and passes through point C(5, 12). If the coordinates of A and B are (-10, -3) and (7, 14), respectively, the x-intercept of CD is Reset Next.
The point Submit Test Reader Tools lies on CD is (17, 0)
Point (-2, 19) lies on CD
Find slope of AB:
\(m = \frac{y2 - y1}{x2-x1}\)
x1, y1 = (-10, -3)x2, y2 = (7, 14)\(m = \frac{14 + 3}{7 +10}\)
m = 1
Therefore,
1 × slope of CD
slope of CD = -1
Substitute m = -1 and (x, y) = (5, 12) in eq. 1
12 = -1(5) + c
c = 12 + 5
c = 17
Substitute m = -1 and c = 17 in eq. 1
y = -x + 17 ------ eq. 2
The x-intercept is found by setting y equal to 0
0 = -x + 17
x = 17
Thus, x intercept of CD is (17, 0)
Substitute (x, y) = (-5, 24) in eq 2
(-5.24) 24-(-5)+17-245+1724 = 22
(doesn't work)
(-2,19) 19-(-2)+17
19=2+17
19
Thus, Point (-2, 19) lies on CD

Weathering and erosion allow for the formation of fossils. Deposition is the breaking up of fossils. Thus, option D is the correct option.
Rocks and minerals on the surface of the Earth weather or dissolve. Erosion is the transportation or movement of the weathered material, while deposition is the depositing of the weathered material. The deposition is the act of silt being dropped by gravity, wind, water, or ice.
Weathering causes sediment to be produced, erosion causes it to be taken away, and deposition causes it to be dumped in a new site. Any process that reduces rocks to tiny fragments is known as weathering. Weathering and the loss of sediments are two aspects of erosion. The deposition is the act of erosional agents discharging sediment.

processes such as wind and water.
A. erosion
B. plate tectonics
C. climate
D weather
Erosion is said to be a naturally occurring phenomenon where natural factors like water , wind or ice take away a part of land , soil and its nutrients by applying their force and pressure on the Earth's surface .
Erosion is the process through which the Earth's surface is eroded away by the action of natural forces like wind and water. As a result, answer option (A) is appropriate.
What is erosion?Erosion is the process through which surface forces (such wind or water flow) remove soil, rock, or dissolved material from one area of the Earth's crust and move it to another, where it is deposited. Weathering, which involves no movement, is different from erosion. Physical or mechanical erosion is the removal of rock or soil as clastic sediment, as opposed to chemical erosion, which is the dissolving of rock or soil in a given area. Eroded sediment or solutes can travel hundreds of meters or thousands of kilometers.
Rainfall, bedrock wear in rivers, coastal erosion by the sea and waves, glacial plucking, abrasion, and scour, areal flooding, wind abrasion, groundwater processes, and mass movement processes including landslides and debris flows in steep terrain are some of the agents of erosion.
Hence, option (A) is accurate.

The Earth takes 24 hours to complete one rotation that is to cover 360 degree of longitude. So to cover one degree of longitude it will take 4 minutes.
What is longitude?Longitude is a geographic coordinate indicating the east-west location of a place on the Earth's surface or another celestial body. It is an angular measurement symbolized by the Greek letter lambda and commonly stated in degrees.
The earth covers 360 degrees of longitudes in one rotation, 24.hours.
Then, 360/24=15 (360 degrees of longitudes/24.hours)
15 degrees of longitude pass in one hour. To traverse one degree of longitude- 60/15=4 (60 minutes 15 degrees of longitude=4 minutes).

explain weathering and types of weathering geo
Weathering: The breakdown or dissolution of rocks and minerals on the Earth's surface is referred to as weathering. Agents of weathering include water, ice, acids, salts, plants, animals, and variations in temperature.
After a rock has been fractured, the fragments of rock and mineral are carried away by a process known as erosion.
The effects of weathering and erosion cannot be resisted by any rock on Earth due to its softness. These processes combined to carve famous sites like Arizona's Grand Canyon.
This enormous canyon measures 446 km (277 miles) in length, up to 29 km (18 miles) in width, and up to 1,600 m (1 mile) in depth.
The rocky terrain of Earth is continually being altered by weathering and erosion. Over time, weathering degrades exposed surfaces.
There are three types of weathering, physical, chemical and biological.
1.Phyisical weathering
Rocks undergo physical weathering when their structure is disrupted by the impacts of temperature change. Water can sometimes help the process.Physical weathering can be divided into two categories:
When water seeps into cracks over time, freezes, and then expands, it undergoes a process called freeze-thaw, which eventually breaks the rock.Exfoliation happens when fissures appear parallel to the surface of the land as a result of the pressure drop during uplift and erosion.2.Chemical weathering
When water dissolves the minerals in a rock, chemical weathering takes place and new compounds are created. Hydrolysis is the name of this process. For instance, when water comes into touch with granite, hydrolysis takes place. Clay minerals are created chemically by the reaction of feldspar crystals within the granite.Chemical weathering processes come in a variety of forms, including solution, hydration, hydrolysis, carbonation, oxidation, reduction, and chelation. Some of these reactions occur more easily when the water is slightly acidic.3.Biological weathering
When plants break apart rocks with their roots or root exudates, this is known as biological weathering. The delayed process could have a significant impact on how a landscape is formed. When biotic activity reaches its maximum, biological weathering declines as soil thickness increases because biotic activity no longer has as much of an impact on weathering.Here are a few illustrations of biological weathering.1.Burrowing creatures
Many animals, from small one-celled organisms to the mammals that establish a temporary or permanent home under soil, contribute to the development of soil. The earthworm is among the most well-known animals that burrow.2.Organic substance
The breakdown of plants and animals results in the addition of organic material to the soil. Other creatures can get nutrients from the remains of once-living things in the soil.3.Lichens
