. A mining company uses technology to study rock deep in Earth. They find evidence of an igneous rock formation underneath Earth’s outer layer. Is it possible that material from this rock formation could ever form sedimentary rock on Earth’s surface? a No, sedimentary rock can only form out of material from other sedimentary rock. There is no way that sedimentary rock can form from material in igneous rock. b No, sedimentary rock forms at Earth’s surface because energy from the sun causes rock to weather, but igneous rock under Earth’s outer layer

The correct answer is option d: "Yes, if igneous rock is moved to Earth’s surface and exposed to energy from the sun, it could weather into small rock pieces that could form sedimentary rock."

Explanation:
Sedimentary rocks are formed by the deposition and gradual accumulation of sediment, which can be derived from a variety of sources, including other sedimentary rocks, igneous rocks, and metamorphic rocks. While it is true that sedimentary rock often forms from the weathering and erosion of pre-existing sedimentary rock, it is not exclusively limited to this process.

In the given scenario, the mining company has found evidence of an igneous rock formation beneath Earth's outer layer. It is possible for material from this rock formation to eventually form sedimentary rock on Earth's surface through a series of geological processes. Here's how it could occur:

1. Upheaval and exposure: Geological processes, such as tectonic plate movements, volcanic activity, or erosion, can cause the igneous rock formation to be uplifted and moved closer to the Earth's surface. These processes can expose the igneous rock to the elements.

2. Weathering and erosion: Once the igneous rock is exposed to the surface, it becomes susceptible to weathering and erosion. Over time, exposure to natural elements like sunlight, wind, water, and temperature variations can break down the igneous rock into smaller rock fragments.

3. Transportation and deposition: Eroded rock fragments from the igneous rock can be transported by natural agents like rivers, wind, or glaciers, and eventually deposited in sedimentary basins or shallow seas. The deposited sediment accumulates layer upon layer over time.

4. Compaction and cementation: As more sediment accumulates, the weight of the overlying layers compresses the lower layers. The pressure causes compaction, squeezing out air and water from the sediment. Minerals dissolved in groundwater act as natural cements, binding the sediment particles together.

5. Lithification: With continued pressure and cementation, the loose sediment transforms into solid rock. This process is known as lithification, and it forms sedimentary rock.

Therefore, if the igneous rock formation is uplifted, exposed to the elements, and undergoes weathering, erosion, transportation, and lithification, it is indeed possible for material from this igneous rock to eventually form sedimentary rock on Earth's surface.

The rock cycle describes the way that rock material cycles through Earth's crust.

All rocks start out as lava or magma that cools into igneous rock.

Explanation:

The Rock Cycle is a process in Earth's crust of creating and forming different types of rocks. Through this process, three primary rocks are formed: Igneous rock, Sediment rocks, and metamorphic rocks.

From the given statements, the statements which are not true about the rock cycle are:

First one, the rock cycle does not desrcibe the way rock material cycles through Earth's crust but it is a process which creates and transforms different types of rocks.

Second statement is also wrong, because only igneous rocks starts out as lava or magma.

Therefore, statement first and second are not true.

Okay so all you need to do if find the process of rock you like and write it down but change what it says a little, here's some(A LOT!!) of info on metamorphic rocks

Metamorphism often occurs on two scales: contact and regional. Contact metamorphism occurs relatively locally, in areas adjacent to igneous intrusions or in areas that are in contact with hot water known as hydrothermal fluids.

Typically this kind of metamorphism is caused by moderate pressure and extreme heat that may last for a period of days to thousands of years. In cases of contact metamorphism, the most extreme metamorphism occurs at the contact point between the parent rock and the intrusive magma or hydrothermal fluid. The degree of metamorphism then decreases rapidly as distance from the heat source increases. Depending on the source, zones of contact metamorphism may range from a few millimeters to tens of meters.

In contrast to contact metamorphism, regional metamorphism occurs over much larger areas. In areas such as rising mountain ranges, large igneous intrusions can form and warp overlying strata increasing the pressures above the intrusion. Also the extreme heat and pressures caused by tectonic forces or deep burial will cause widespread metamorphism.

A river washes sediment into the ocean. The sediment is composed of plankton and very fine particles of weathered silicate rock smaller than 0.05 mm in size. The material drifts down slowly through the deep, quiet water and collects on the sea floor. If buried, what type of rock will this sedimentary deposit most likely become? a. Tufa b. Shale c. Conglomerate d. Sandstone

Step-by-step answer

P Answered by Master

Option (A)

Explanation:

Tufa is a sedimentary limestone rock which is primarily comprised of calcium carbonate (CaCO₃). It is pore spaces in it. It is primarily formed from the precipitation of calcite, either chemically or biologically, which are derived frm the surface water or the ground water.

This type of sedimentary rock is formed from the deposition of materials or sediments that are carried by the rivers into the deeper zone of ocean, and after compaction and lithification, forms the rock called 'Tufa'.

Thus, the correct answer is option (A).

The projection seeks to balance different types of distortion. The projection isn't perfect, but it is considered more visually appealing than others. It balances small distortions of area, shape, distance, and direction.

Why did they set up the system of apartheid in South Africa in 1948

Step-by-step answer

P Answered by PhD

Answer:
Their goal was not only to separate South Africa's white minority from its non-white majority, but also to separate non-whites from each other, and to divide black South Africans along tribal lines in order to decrease their political power.
Strategists in the National Party invented apartheid as a means to cement their control over the economic and social system. Initially, aim of the apartheid was to maintain white domination while extending racial separation. ... With the enactment of apartheid laws in 1948, racial discrimination was institutionalized.

Thus question lacks a picture or option, but nevertheless:

Answer:

There are 3 types of friction:1) Static friction - when you apply force and the object does not move.2) Sliding friction - when the surface if the object moves on other.3) Rolling friction - when any wheel or ball moves on any surface rolling friction is applied. it is very less than sliding friction.
