What does shear stress do to rocks? Shearing in rocks. The white quartz vein has been elongated by shear. When stress causes a material to change shape, it has undergone strain or deformation. Deformed rocks are common in geologically active areas. What is the deformation caused by stress? There are three types of stress: compression, […]

Which energy form Cannot be converted to others? Thermal energy is unique because it cannot be converted to other forms of energy. What is the main sources of energy on the earth? One of the most important sources of energy is the sun. The energy of the sun is the original source of most of […]

What is the pH of alkaline solutions? Introduction to pH – acidic and basic (alkaline) pH Ion Concentration (gram equivalent per liter) Type of Solution 6 0.000001 Acid Solution – Hydrogen ions – H+ 7 0.0000001 Neutral Solution (pure neutral water) 8 0.000001 Basic (alkaline) Solution – Hydroxide ions – OH- 9 0.00001 How do […]

What are the causes of bad posture? Common causes of bad posture Pain or past injuries. When you experience pain in your back or neck muscles or any other part of the body, you tend to overcome the pain by holding your body in a different position. Low nutritional state. Hereditary. Extra weight. Habit. Your […]

Can you pressure cook and then slow cook? It’s no surprise that pressure cooking is faster than slow cooking, but did you know that you can get the same fall-apart tender results using a fraction of the energy too? Cooking Temperature – Get the same results faster! … Which is the best pressure cooker to […]

Can an object gain or lose neutrons? If an atom were to gain or lose neutrons it becomes an isotope. If it gains a neutron it become an isotope called deuterium. Since the atomic mass is the total of the number of protons and neutrons, an isotope would have a different atomic mass, but the […]

Is phyletic gradualism real? Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis). Who proposed gradualism and punctuated equilibrium? The idea […]

Can we go below 0 Kelvin? Summary: On the absolute temperature scale, which is used by physicists and is also called the Kelvin scale, it is not possible to go below zero – at least not in the sense of getting colder than zero kelvin. At zero kelvin (minus 273 degrees Celsius) the particles stop […]

What is the area between hills called? areas between hills Areas between hills VALES Areas between hills DALES What is a gap between mountains called? A gap is a low area between two higher-elevation landmasses, such as mountains. The most rugged gaps are often called “notches.” Notches are rarely crossed, and usually marked by steep […]

What does the chromosome theory explain? Key points: Boveri and Sutton’s chromosome theory of inheritance states that genes are found at specific locations on chromosomes, and that the behavior of chromosomes during meiosis can explain Mendel’s laws of inheritance. Who is responsible for the chromosome theory? Walter Sutton What is the chromosome theory of inheritance […]
