Does the Earth take exactly 365 days every time it orbits around the Sun?

The property that remains constant during physical and chemical changes is the number of atoms in a system. A physical change is one in which no new substance is formed, but rather the appearance or composition of a material is changed.

When an object is broken into two pieces, for example, it becomes a physical change. The materials that the object is composed of have not changed, but the object itself has changed shape. A chemical change, on the other hand, is one in which new substances are formed. When magnesium is burned in air, for example, magnesium oxide is formed. The properties of the magnesium and oxygen atoms have altered, causing them to join together to create a new substance. Heat, light, gas production, precipitate formation, color change, and odor change are all signs of a chemical reaction.

Physical and chemical changes are alike in that they both alter the properties of a material. For example, if a piece of iron is heated, it will glow red and become more malleable. If a piece of iron is burned, it will oxidize and become rust. The number of atoms in the material, on the other hand, remains constant. When iron is oxidized to rust, the number of iron and oxygen atoms in the system remains the same, although the atoms' configuration and properties have changed. Thus, it can be concluded that the number of atoms remains constant during both physical and chemical changes.

Stone columns are very useful for stabilizing slopes and avoiding liquefaction because they boost soil shear strength.

There are two main ways that stone columns reduce liquefaction: 1. By improving drainage, which releases extra pore water pressure brought on by seismic loading, and by raising SPT values, which affect the Cyclic Stress Ratio.

Sandalloid soils frequently utilize stone column treatment to reduce the risk of liquefaction. This approach may not be successful for silts and sands with fines contents larger than 15-20%, according to research and experience, but it is effective for clean sands. An alternative to the stone column approach entails adding pre-fabricated vertical wick drains that are installed before the stone columns are constructed.

Liquefaction requires sufficient pressure to compress gas molecules, low temperature to decrease their kinetic energy, and suitable conditions such as absence of impurities for the process to occur successfully.

The process of liquefaction can occur under specific conditions. The three key requirements for liquefaction to occur are:

High pressure: High pressure is frequently necessary for liquefaction in order to compress a substance and bring its particles close together. The intermolecular forces that retain the substance in a solid or gaseous form can be overcome by pressure. By raising the pressure, the material's particles are more tightly packed, which speeds up the change from a solid to a liquid state.

Proper temperature: Whether a substance can exist as a solid, liquid, or gas depends greatly on temperature. The substance needs to be cooled to a level below its critical temperature in order to liquefy. The greatest temperature at which a substance can liquefy regardless of applied pressure is known as the critical temperature. The substance's particles lose kinetic energy when the temperature is lowered, slow down, and move closer to one another, eventually creating a liquid.

Suitable substance: Not all substances can be liquefied under normal conditions. The chemical properties of the substance must allow for liquefaction to occur. For example, gases like nitrogen, oxygen, and carbon dioxide can be liquefied under appropriate pressure and temperature conditions. However, substances with exceptionally high boiling points or strong intermolecular forces, such as noble gases like helium, are challenging to liquefy using conventional methods.

By combining these three requirements—sufficient pressure, appropriate temperature, and a suitable substance—it becomes possible to induce liquefaction in various gases, facilitating their transition from a gas to a liquid state.

The process that transforms bedrock into the mineral component of soil is weathering. This is the physical, chemical, and biological breakdown of rocks and minerals by a combination of water, wind, temperature changes, and organisms.

There are two types of weathering processes: mechanical and chemical.

Mechanical weathering is the physical breakdown of rock without any change in its chemical composition. Chemical weathering, on the other hand, is the process in which the minerals in the rocks undergo chemical changes. The bedrock is broken down into smaller pieces by mechanical weathering, and then it undergoes chemical changes.

These changes transform the rock's minerals into the mineral components of soil. The action of water is the most important agent of weathering. Rainwater contains dissolved carbon dioxide which makes it slightly acidic. When it falls on rocks, it reacts with the minerals and dissolves them. The water seeps into the rocks and expands as it freezes. The expansion breaks the rocks into smaller pieces, and over time, this process creates soil.

The most widely accepted explanation for the mechanism that generates earthquakes is the elastic rebound theory.

The elastic rebound theory is a widely accepted explanation of how earthquakes occur. According to this theory, earthquakes are caused by the gradual accumulation of elastic strain energy in rocks, which is released suddenly when there is a sudden shift along a fault.

The rocks on both sides of a fault are subjected to forces that cause them to bend and stretch. This deformation of rocks along a fault is known as elastic strain. Over time, this strain energy builds up until the rock can no longer resist the pressure, causing it to fracture along the fault.

The sudden release of energy is what causes an earthquake. The rocks snap back to their original, undeformed shape, releasing the energy that has been stored in them. This sudden motion sends seismic waves through the earth, which is what we feel during an earthquake.

In conclusion, the correct answer is a) elastic rebound theory.

A narrow strip of land that connects two larger land masses and separates two water bodies is called an Isthmus.

Since Isthmus lies at the connecting point of two large landmasses, its strategic location makes it ideal for setting up ports, canals, military camps, stations, etc. A natural outcome of such structures would be enhanced communication, exchange of knowledge, culture, and robust trade through this connection.

Some examples include the Isthmus of Panama which links continents of North and South America and separates the Pacific Ocean from the Atlantic Ocean. The Isthmus of Suez links the continents of Asia and Africa and separates the Red Sea from the Mediterranean Sea.

Both the above-mentioned Isthmus are expeditors of large-scale trade across the world. About 14,000 ships cross the Panama Canal between the Atlantic and Pacific Oceans every year.
