Rocks formed from materials eroded from already existing rocks, from the evaporation of water, from the hard outer shells of marine organisms, or from decomposing vegetation are called sedimentary rock.
Sedimentary Rock Formation ProcessThe process of forming sedimentary rocks involves four main processes, namely weathering, transportation, deposition, and compaction. The following is the process of formation of sedimentary rocks:
1. Weathering
Is the breakdown of rock, soil, minerals, and wood and man-made materials through contact with the Earth's atmosphere, waters, and biological organisms. Weathering occurs in place of origin with little or no movement.
Weathering involves the movement of rocks and minerals by agents, such as water, ice, snow, wind, waves, and gravity to be transported and stored in other locations. There are three important classifications of weathering processes, namely physical, chemical and biological weathering.
a. Physical Weathering, is a weathering process that involves direct contact with atmospheric conditions, such as heat, water, ice, and pressure.
b. Chemical weathering is weathering due to the direct effects of atmospheric chemicals or biologically produced chemicals.
c. Biological Weathering, is weathering caused by living things and caused by the processes of animal, plant and human organisms.
2. Transportation
The process of transporting material from the place of origin to the place of deposition. This process requires transportation agents in the form of gravity, wind, glaciers, and water.
3. Precipitation
Sedimentation is the geological process when sediments resulting from weathering processes or soil and rock are added to a lower lying area transported by wind, glaciers, water, and gravity.
4. Compaction and Cementation
Compaction occurs when sediments are buried deeply, placing them under pressure due to the weight of the layer above them.
Meanwhile, cement is a new mineral that attaches to sediment grains like cement binds sand grains to building materials.

what forecasting technique says that upstream weather will persist, and then move on to affect new areas in its path?
The forecasting technique that says that upstream weather will persist before then move on to affect new areas in its path is the trend technique or trend method.
Trend technique is a technique in forecasting that is used when the related phenomenon is in a steady state or is moving at a constant speed. It's more accurate on a shorter time scale (minutes to hours), so it's also known as the "nowcasting" technique. This method involves finding out the speed and direction of movement for things like fronts, pressure centers, and areas of precipitation and clouds.
Besides the trend technique, there are other techniques that can be used to produce a forecast. Some examples are the persistence method, climatology method, analog method, and numerical weather prediction.

One problem that can result from agriculture is salinization (2 points).
i. Describe how salinization occurs
ii. Describe one method to prevent or remediate soil salinization
When dissolved salts in water tables raise to the soil's surface and build up as water evaporates, salinization happens. The replacement of deeply rooted vegetation, like trees, with species with shorter roots, like grasses, frequently causes a rise in the water table.
What are the method to prevent soil salinization?The effectiveness of irrigation canals can be increased, salty drainage water can be captured and treated, desalination facilities can be installed, and more water can be pumped into aquifers as solutions. Crops can also be mulched to conserve water.

the process in which sediments, soil and rocks are added to a land form or land mass.a. trueb. false
This statement is true. Deposition is a geological process that involves the addition of soil, rocks, and sediments to a landform or landmass.
Transported by wind, ice, water, and gravity, previously weathered surface material is deposited when enough kinetic energy in the fluid is lost, forming layers of sediment.
The null-point hypothesis states that deposition occurs when sediment transportation-related forces are no longer strong enough to overcome gravity and friction-related factors, which provide a resistance to motion. Deposition also refers to the buildup of sediment caused by organic or chemical processes. Chalk contains small calcium carbonate skeletons from marine plankton, which when deposited caused chemical reactions (diagenesis) to deposit more calcium carbonate.

A sand dune is a pile of loose sand grains of sand that have accumulated due to wind movement.
Only under certain conditions, such as the following, can sand dunes form:
The occurrence of a sizable sand supplyA steady wind source to transport and drop sandThe presence of a region with some vegetation, such as a dried-up riverbed, beach, waterfront, island, or desertThe existence of a protected area where a new sand dune can form, such as a rocks, tree, or another dune.Winds that are blowing at least 17 miles an hourLeeward and windward faces are the two sides or sides of sand dunes. The Leeward side refers to the area of the sand dune protected from the wind or facing away from it, whereas the windward side designates the area of the dune facing the wind.
Usually, the wind will blow sand over the dune's peak, creating a steep slope on the leeward side. The slip-face of the dune or the downwash side of the sand dune are terms used to describe this peak. The gently sloped part of the dune is represented by the windward side in contrast.

Agriculture is reported to be the main cause of water deterioration and the most prevalent type of water contamination in the US and around the world.According to reports, agricultural pollution is at its highest point in the United States. As a result, the most likely reason for the continued degradation of water quality is that a large portion of today's pollution is caused by pollutants being exposed to rainwater and runoff, which is affecting the water.The plant in this case is the source, and it discharges filthy water into the lake.It is possible to transfer this lake water to other locations.So, industry waste water is the primary source of Point source pollution.

how do we use magnetic alignment of minerals in rocks to understand plate movements over time? (especially sea floor rocks and paleogeography of supercontinents)
Geologists can use the magnetic alignment of minerals in rocks to understand plate movements over time by studying the patterns of magnetic minerals in rocks. When rocks form, the minerals within them become aligned with the Earth's magnetic field. This alignment is preserved in the rock as it cools and solidifies. By studying the alignment of these magnetic minerals in rocks, geologists can determine the orientation of the Earth's magnetic field at the time the rock formed.
Over time, the Earth's magnetic field has reversed many times, with the north and south magnetic poles switching places. By studying the alignment of magnetic minerals in rocks of different ages, geologists can determine when these reversals occurred. This information can then be used to understand the movement of tectonic plates over time, as well as the formation and breakup of supercontinents.
For example, geologists can study the alignment of magnetic minerals in rocks on the sea floor to understand the movement of tectonic plates over time. By looking at the patterns of magnetic alignment in these rocks, geologists can determine the direction and rate of movement of the plates and how they have changed over time. This information can be used to understand the formation and breakup of supercontinents, as well as the history of plate tectonics on Earth.

Large tsunamis with a local scope can be produced by landslides into bays and lakes. Due to their constrictive topography, bays and lakes frequently experience massive tsunamis.
A bay is a body of water that is partially enclosed by land; it is often smaller and less constrained than a gulf. The bay's mouth, however, is larger than the gulf. The underwater topography offshore mostly determines the wave height, which rises as it approaches the beach. Greater tsunami waves typically result from steeper shorelines. Lacustrine conditions are also susceptible to tsunamis. Vast-scale mass-movement mechanisms that displace large volumes of water and are sparked by seismic or aseismic phenomena are the principal causes of the enormous tsunamis in lakes.
