Answer:
Mineral classification is based upon the chemical composition of the minerals. There exist at least 3000 different kinds of minerals which makes it necessary to have a system to classify them.
Carbonates are a class of minerals that are composed of carbon, oxygen, together with a metallic element. Calcite better known as calcium carbonate is an example of a mineral of this type.
Halides are made up of halogen elements like bromine, chlorine, fluorine and iodine, together with metallic elements. Halides are super soft and are highly soluble in water. A common example under this category is halite which is known as sodium chloride.
Mineraloids are those minerals that do not fit perfectly into the other 8 classes of minerals. They include: amber, jet, mother of pearl and opal.
Native elements are a class of pure minerals. A lot of minerals exist in combinations of numerous chemical compounds. Native elements are those that occur naturally in a pure state, for example copper is a single element mineral.
Oxides arise when metals are combined with oxygen. This class consists of dull ores such as bauxite and gems such as sapphire and ruby.
Phosphates are created when there is break down of other minerals through weathering. They are usually bright in color and do not occur as much as the other groups of minerals.
Silicates form the largest family of minerals. They arise from the combination of metals with oxygen and silicon. There exist more silicates on earth than all the other minerals added together. Mica is a common example under this category.
Sulfates form from the combination of sulfur compounds with oxygen and metals. This is also a large family of minerals, which are soft and translucent in nature. Barite is a good example of a sulfate.
Sulfides are composed of sulfur compounds often together with a metal. They are heavy and brittle in nature. Pyrite is an example of a sulfide.

How do waves from an earthquake move differently at the surface of the earth and through the body of the earth?
Answer:
Explanation:
Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves. The wave can move through solid rock and fluids, like water or the liquid layers of the earth.
The waves from an earthquake move differently at the surface of the earth as it flow in a vibration way across the planet's surface. The Earth's deeper layers can be penetrated by body waves.
What is Earthquake?Earthquake is referred to as natural disaters which takes place due to the movement of tectonic plates as there is a group of plates that moves get collapsed with each other causing vibrations and coming as an Earthquake.
In comparison to body waves, which can only pass through solids, seismic waves can only move along the surface of the Earth. The reason for this is that gases and liquids are not shape-resistant.
As one moves away from an earthquake, body waves in the earth's interior lose intensity quickly due to the spread of the waves inside the earth's volume.

Explain how plate boundaries are connected to the
slow movement of solid rock in the mantle.
Answer:
The movement of warmth by convection within the layer causes the rock of the mantle to slowly move in large streams. The solid rock of the layer is resting directly on high of the solid rock of the layer.
Hope it helps!
The mantle is defined as the molten rock in which acts like a conveyor belt for the plates. The plate boundaries are connected to the slow movement of solid rock that is due to convection currents.
Convection currents can be explained as:
Convection currents are a process in which is generated by the rising and falling of the heat. It is caused due to radioactive decay. The convection causes the movement of the plates, which diverges near the Earth's crust. The plates will move apart from each other.The convection currents when converge, then the plates will move towards each other.
Thus, the movement in the mantle is caused by the convection currents.

А
10:03:00 am
C
10:09:40 am
B
10:03:40 am
D
10:10:20 am
Answer:
B
Explanation:
The P-wave reached to the seismic station in half time as compared to S-wave.
The P-wave arrive at the seismic station is 10:03:40 am because of the double speed of P-wave as compared to S-wave. In the Earth, P waves travel at speeds of about 6 km per second in surface rock to about 10.4 km per second means at average speed of 8 km per second.
While on the other hand, S-wave moves at a speed of 1 to 8 km per second means at an average speed of 4 km per second so we can conclude that the P-wave reached to the seismic station in half time as compared to S-wave.

Describe Robert Adam's Etruscan style furniture.
Answer: Robert Adam (1728 – 92) was one of the most important British architects working in the Neoclassical style – a movement in the decorative and visual arts that drew inspiration from the 'classical' art and culture of Ancient Greece and Rome.
Born in Kirkaldy, Scotland, Robert Adam was the son of the established architect William Adam (1689 – 1748) and followed him into the family practice. In 1754 he embarked on a Grand Tour, spending five years in France and Italy visiting classical sites and studying architecture under the French draughtsman Charles-Louis Clérisseau and Italian artist Giovanni Battista Piranesi. On his return, Adam established his own practice in London with his brother James. Although classical architecture was already becoming popular, Adam developed a distinctive and highly individual style that was applied to all elements of interior decoration, from ceilings, walls, and floors to furniture, silver, and ceramics. The 'Adam Style', as it became known, was enormously popular and had a lasting influence on British architecture and interior design.
Letters from Adam whilst in Italy in 1757 show that he had decided to become the most prominent architect in Britain. This was a normal aspiration for a young British architect on the Grand Tour, but Adam was unusual in wanting to bring to Britain what he called the "one true grand and simple style". Unlike many of his contemporaries, Adam did not have a ready-made network of noble friends and relations and was too busy learning to draw to make the contacts that would provide clients for his future practice. But what he lacked in contacts, Adam made up for in drive and determination, combined with plenty of luck.
On his return to Britain in 1758, Adam was invited to Kedleston Hall, having impressed its owner, Lord Scarsdale, with his Italian drawings. It was here that Scarsdale was having a house constructed and James Stuart, another pioneer of Neoclassicism, was working on the interiors. Adam was able to get Stuart dismissed from the project by attacking his Neoclassical designs as "so excessively and ridiculously bad they beggared all description", and went on to complete the house himself. Adam's Scottish origins also played a crucial part in helping him to become appointed by many prestigious clients. Lord Bute, a fellow Scot, and minister of King George III aided Adam in being appointed as royal architect, together with William Chambers.
Adam's own theory of design was based on the principle of 'movement' – the rise and fall, and advancement and recession of forms. The essence of the 'Adam Style' lay in his use of ornament. Looking back in 1812, English architect, Sir John Soane refers to the Adam Style as "...light and fanciful...This taste soon became general; everything was Adamitic".
Another crucial element was his insistence on a stylistic coherence across every element of his interiors. The idea of coordinated design had become widespread in Britain – encouraged by the relative ease with which repetitious and regular Neoclassical ornament could be produced in flat patterns or in low relief which could be easily fitted together in different combinations.
The Adam brothers' lavish publication, Works in Architecture, published in parts from 1773, played a significant role in the dissemination of their style and included illustrations encouraging the idea of the total interior. Its characteristically boastful text, which credited the complete change in national taste to the Adam brothers, established their reputation for the future. In it, they stated that Graeco-Roman examples should "serve as models which we should imitate, and as standards by which we ought to judge".
Adam's version of the Neoclassical set off a revolution in style. His distinctive decorative system used a limited range of ornament, brilliantly distilled from ancient and Renaissance sources, chiefly wall paintings and room decorations. By the early 1760s, Adam had developed a form of interior decoration that sought to suggest the rooms of the ancients but adapted to modern uses. Ceilings and walls, and often floors, were covered with continuous areas of small-scale ornament, which played down the architectural definition.
Neoclassicism took about ten years to spread beyond the fashionable elite. By the early 1770s, full-blown neo-classical furniture had penetrated the general market, and in 1774, the architect John Carter could describe a pair of Adam-style panels shown in the Builder's Magazine as being "in the present reigning taste".
