What are the 4 types of sedimentary rocks? The accumulation of plant matter, such as at the bottom of a swamp, is referred to as organic sedimentation. Thus, there are 4 major types of sedimentary rocks: Clastic Sedimentary Rocks, Chemical Sedimentary Rocks, Biochemical Sedimentary Rocks, and Organic Sedimentary Rocks. What are the 10 steps to […]

What does liquid do when warmed? If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer. Liquids evaporate faster as they heat up and more […]

What is point of view in an essay? Point of view refers to who is telling or narrating a story. A story can be told from the first person, second person or third person point of view (POV). The POV of a story is how the writer wants to convey the experience to the reader. […]

What are the five elements of inquiry based instruction? There are five elements of inquiry-based learning. The five components include: Essential Questions, Student Engagement, Cooperative Interaction, Performance Evaluation, and Variety of Responses. Lessons begin with a question that sparks curiosity and a sense of wonder. Students are encouraged to ask questions. What is the importance […]

How do searchlight signals work? The searchlight signal is one of the few signals that uses a reflector. The reflector is elliptical in shape, and the bulb is put at the focus point of the reflector. The placement of the bulb is positioned so that the light beam is focused to another focal point before […]

Do you weigh the same in water? Yes we do weigh lesser in water , especially in a swimming pool which contains salty water . This is because when we immerse ourselves in any fluid then the volume of water equal to our volume gets displaced (the water level rises). Do objects weigh the same […]

Will humans ever travel to other galaxies? The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible. How old is our galaxy? 13.51 billion years How long before our […]

Can DNA tell if you are half-siblings? DNA is unique to each individual unless he or she is an identical twin. However, DNA testing can help you identify siblings and half-siblings because you share more DNA with those people than with people not related to you. But simply sharing DNA with someone doesn’t necessarily mean […]

Is Black an absence of color? Is black the absence of color? In science, black is the absence of light. And color is a phenomenon of light. But a black object or black images printed on white paper are made from pigment, not light. Is black or white absence of color? In physics, a color […]

What is the use of Maxwell equation in thermodynamics? Maxwell relations are thermodynamic equations which establish the relations between various thermodynamic quantities (e.g., pressure, P, volume, V, Entropy, S, and temperature, T) in equilibrium thermodynamics via other fundamental quantities known as thermodynamical potentials—the most important being internal energy. What is B in Maxwell equation? The […]
