A. Mode of Formation: Sedimentary rocks are formed when sediment is deposited and compacted over time. This sediment can be transported by rivers, wind, glaciers, and other geological processes.
B. Characteristics: Sedimentary rocks typically have layered or stratified textures, with different colors and compositions depending on the type of sedimentary material. Sedimentary rocks may also contain fossils or other signs of ancient life.
C. Types: Sedimentary rocks can be divided into two main types, clastic and chemical. Clastic sedimentary rocks such as sandstone and shale are composed of pieces of other rocks that have been broken down and cemented together. Chemical sedimentary rocks such as limestone and dolomite are formed from the chemical precipitation of material from water.
D. Examples: Examples of sedimentary rocks include sandstone, shale, limestone, dolomite, and coal.

Sedimentary rocks are the most common rocks exposed on Earth’s surface but are only a minor constituent of the entire crust, which is dominated by igneous and metamorphic rocks. Sedimentary rocks are produced by the weathering of preexisting rocks and the subsequent transportation and deposition of the weathering products.
a) The mode of formation of sedimentary rocks is lithification-:
To begin, existing rocks are eroded and weathered, which entails the physical breakdown of the rocks and the subsequent transfer of the debris away from the original rock.Sediments are frequently created as a result of chemical degradation caused by rainfall or dissolution. As most sediments are carried by wind or flowing volumes of water such as rivers or glacial ice, gravity plays a significant role in assisting transportation.The sediments begin to deposit once they have been transported. When subjected to an appropriate temperature and air pressure, slit deposition can also occur as a result of precipitation. Sedimentary rocks like organic reefs are one example.Once the sediments begin to deposit, layers of these sediments begin to pile up on top of one another in a process known as burial.Through the process of lithification, these sediments become compacted and cemented into solid rocks once they reach a particular depth. Sedimentary rocks are created in this manner. Chalk, clay, flint, and shale are some of the most prevalent sedimentary rocks.b) Characteristics of sedimentary rocks
Sedimentary Rocks have mud cracks.
These rocks house beddings that are of different sizes ranging from thin laminas to the thick stratas.
Sedimentary rocks have more fossils i.e. the remains of living organisms in their rock layers.
They have a different color which primarily ranges from white to red.
The raindrops leave marks on sedimentary rocks known as rain prints. Similarly, the rocks that travel with water feature ripple marks.
c) Types of sedimentary rocks
Organic Sedimentary Rocks
This rock type mainly consists of coal and limestones, which are formed due to the accumulation and deposition of dead plants and animals in rock layers.
Clastic Sedimentary Rocks
This type of rock is formed when rock layers are formed due to the mechanical weathering of different rock types.
Chemical Sedimentary Rocks
This type of rock is created when minerals that are present in rock forms undergo a chemical reaction that causes them to cool as precipitates over time before changing back to rock form.
d) Examples of sedimentary rocks
Coal, Limestone, Dolomite, Chert, Flint, Gypsum, Rock Salt

You are studying a sample of igneous rock. The rock formed on the surface of Earth. It’s made mostly of light-colored minerals. The sample has just a few specks of dark-colored minerals. Classify the rock by type and composition.
Answer: Rhyolite
Explanation:
Rhyolite is an extrusive igneous rock. It is formed by the volcanic eruption. This rock have glassy appearance. It is a fine grained rock. It has light color due to small grain size and deposition of silica so the color is pink or gray. It also comprises of dark colored mineral specks like quartz, sanidine, plagioclase, biotite, and others. This rock also comprises of trapped gases. The rock appears in the crystalline form and appearance. The low content of the mafic minerals also contribute to the light color of the rhyolite rock.

What is a “jet stream"? What type of air does this one separate
Answer:
A jet stream is a type of air current that forms high in the atmosphere. On average, jet streams move at about 110 miles per hour. But dramatic temperature differences between the warm and cool air masses can cause jet streams to move at much higher speeds — 250 miles per hour or faster.
Explanation:
Jets streams play a key role in determining the weather because they usually separate colder air and warmer air. Jet streams generally push air masses around, moving weather systems to new areas and even causing them to stall if they have moved too far away.

Which current has a cooling effect on the climate of the west coast of South America?
(1) Falkland Current
(2) Peru Current
(3) Benguela Current

Answer:
(2) Peru Current
Explanation:
The Peru Current, also known as the Humboldt Current. This current was has a very important cooling effect over the west coast of South America, from the southern tip of Ecuador, passing through the Peruvian cost, to the mid coast of Chile.
This current makes coastal areas like central Peru, which should be hot, rainy, and tropical according to latitude, a lot cooler and drier. In fact, the most arid area in the world is an effect of the current, the Atacama desert in Chile.

Explanation:
Despite the distance between California and Australia, the value of gold
in the 1800s spurred Gold Rushes on both the North American and
Australian Continents which allowed innovations in mining to spread
between the two countries. This is called-
Select one:
a. Convergence
b.Divergence
c.Transmission
d.Outsourcing
The provocation of Gold Rushes leading to the integration of both the North American and Australian Continents for innovations regarding mining would be called:
A). Convergence
'Convergence' is described as the process of 'merging of distinct technologies or devices into a unified whole.'In the given situation, the coming together of two continents i.e. North American, as well as, Australian continents to work together in the field of mining technology would be called 'convergence.'Since the innovation brought the two continents in unity to work in integration for further development and innovation, it is convergence.Hence, option A is the correct answer.

Identify major centers of domestication of plants and animals.
Explain how plants and animals diffused globally.
Answer:
Southwest Asia, Southeast Asia, and the Americas.
Explanation:
Major centers of domestication of plants and animals are Southwest Asia which also known as the Fertile Crescent, Southeast Asia, and the Americas. Plants and animals diffused globally because of the interaction of different cultures with each other. When the two different cultures interact with each other through migration from one region to the new one, both cultures exchanges some of the ways of living and methods. When the English people came to the New world, they introduced cultivation of corn crop which leads to diffusion of plants in the America.
