What are civil service jobs ?All state and federal government agencies fall under the umbrella of the civil services, which also includes some of the less well-known departments of the Indian Railways, Revenue Service, Police Service, Audits, Customs, and IAS (Indian Administrative Service).
Becoming a public servant, however, does not automatically make one a civil servant. The civil service excludes public organizations like local governments, the military forces.
An employee of the civil service is essentially hired by the government to impartially implement their policies and laws. They frequently work in the public sector. Therefore, a police officer is an example of civil service job.

How old is a rock with a half life of 5,280 years
if 1/8th of the parent material is left?
Answer:
A rock with a half-life of 5,280 years having 1/8th of the parent material left will be 15,840 years old.
Explanation:
The half-life of a material is the time needed for only half of the parent material to be left, while half has is gone, or rather has disintegrated. The half-life is used further into the falling apart of the parent material though, with the same principle being applied. Practically, from the 1/2 of the parent material being left, the half-life of it would mean 1/4 of the parent material being left, and from that 1/4, the half-life would be at 1/8 of the parent material being left, and so one, by simply dividing in two.
In this case, having a half-life of the rock of 5,280 years, we will simply need to add that amount of years on every next phase. So, the half-life is 5,280 when 1/ of the parent material is left. When 1/4 of the parent material will be left we will have an age of 10,560 years, while when only 1/8 is left, we will have 15,840 years of age for the rock.

Which is one way poor use of fertilizers in agriculture can affect the environment
A. It can increase the ability of many species to find suitable habitats
B. It can cause pollution of water in lakes and rivers
C. It can cause an increase in greenhouse gases
D. It can reduce the amount of sediment in the local waterways
Answer:
B. It can cause pollution of water in lakes and rivers
Explanation:
Poor use of fertilizers in Agriculture can affect the environment because they cause pollution of water in lakes and rivers.
Pollution is the introduction of filth or unwanted materials into the environment.
When fertilizers are poorly applied on farms, they can cause pollution of nearby water bodies. Rain water usually during a down pour can wash them off into surrounding water bodies. They can also even infiltrate into the ground water systems. On getting into the rivers and lakes the alter the chemical balance and lead to severe pollution. One of such is eutrophication.So, poorly applied fertilizers can cause pollution of water in lakes and rivers.
What happens due to divergent plate movement?
A. Mountain formation
B. Volcano eruption
C. Seafloor spreading
D. Earthquakes
Spreading of the seafloor occurs along divergent plate boundaries. When tectonic plates progressively migrate apart from one another, heat produced by the mantle's convection currents causes the crust to become more flexible and thinner. Thus, option C is correct.
What is the seafloor spreading due to divergent plate?As oceanic plates diverge, tensional stress causes fractures in the lithosphere. Although there is often extensive magma activity at spreading ridges, the driving factor for seafloor spreading ridges is tectonic plate slab pull at subduction zones.
Less dense material tends to ascend, often forming mountains or elevated seafloor regions. Eventually, the crust breaks.
Oceanic crust has a propensity to subduct, or dive under, neighboring continental plates or younger segments of oceanic crust because it cools and eventually becomes denser than the asthenosphere beneath.
Therefore, Seafloor spreading happens due to divergent plate movement.

Describe three characteristics of lava? Explain
Answer:Volcanoes
Volcanoes are a good way for the earth to blow off a little steam. More correctly, volcanoes are vents in the earth's crust through which lava, rock fragments, hot vapor and gases are ejected. And, while they are all natural events in the life of Earth, there are different types of volcanoes. The types of volcanoes are differentiated based on their size, composition and explosive style.
In fact, we could compare the different types of volcanoes to players on a football team. The tall and impressive composite cone volcanoes are much like the strong and confident quarterback. The broad and lower-to-the-ground shield volcanoes are much like the beefy lineman of the team. And, the fast-growing but smaller cinder cone volcanoes are much like the quick-moving and compactly built running backs of our team. Let's take a closer look at these three main types of volcanoes.
Composite Cone Volcanoes
Composite cone volcanoes, which are also called 'stratovolcanoes' or simply 'composite volcanoes,' are cone-shaped volcanoes composed of layers of lava, ash and rock debris. Composite cone volcanoes are grand sites and can grow to heights of 8,000 feet or more. Mount St. Helens and Mount Rainier, which are both found in Washington State, are impressive examples of composite volcanoes.
These steep-sided volcanoes erupt in an explosive manner. In fact, Mount Vesuvius is a composite volcano that is most famous for burying the ancient Roman city of Pompeii in up to 20 feet of volcanic ash in 79 AD. The explosiveness of their eruptions is due to the thick, highly viscous lava that is produced by composite cone volcanoes.
And, this viscous lava has a lot to do with why they are shaped the way they are. The thick lava cannot travel far down the slope of the volcano before it cools. This makes the sides of the composite volcano steep. These explosive volcanoes also spew out eruptions of small rock and ash, which gets deposited on the sides of the volcano. Therefore, we see that composite volcanoes are composed of alternating layers of hardened lava, volcanic ash and rock fragments, which is why they are called 'composite.'

Calcium carbonate can break down to form calcium oxide and carbon dioxide. CaCO3 → CaO + CO2 The oxygen atoms on the product side are not balanced because there are only two oxygen atoms in CO2 not balanced because there is only one oxygen atom in CaO. balanced because the total number of oxygen atoms is 3. balanced when a coefficient of 3 is placed in front of CO2.
Calcium carbonate can break down to form calcium oxide and carbon dioxide. The balanced chemical equation has been 3 CaCO₃ ⇒ 3 CaO + 3CO₂
What is balanced chemical equation ?The term balanced chemical equation is defined as the total number of mass of reactant is exactly equal to the total number of mass of product.
The balanced equation can be given to follow the law of conservation of mass. With equal number of atoms of all elements are present on the product and the reactant side in the reaction.
The given equation is written with addition of 3 as a coefficient to the carbon dioxide in above reaction is as follows:
CaCO₃ ⇒ CaO + 3CO₂
The number of elements of oxygen in reaction on product side has been 6 atoms for carbon dioxide and 1 oxygen atom for calcium oxide. The total oxygen on product side has been 7. The reactant has the presence of 3 oxygen atoms. So, for balancing the equation.
The reaction has been balanced with equal atoms on both the sides as follows:
3 CaCO₃ ⇒ 3 CaO + 3CO₂
