What do the lithosphere and asthenosphere have in common? Both the lithosphere and asthenosphere are part of Earth and are made of similar material. Lithosphere is made up of Earth’s outermost layer, the crust, and the uppermost portion of the mantle. In comparison, the asthenosphere is the upper portion of Earth’s mantle (which is also […]
Why is phrenology no longer accepted?
Why is phrenology no longer accepted? Phrenology was mostly discredited as a scientific theory by the 1840s. This was due only in part to a growing amount of evidence against phrenology. Phrenologists had never been able to agree on the most basic mental organ numbers, going from 27 to over 40, and had difficulty locating […]
What are the evidences of continental drift theory?
What are the evidences of continental drift theory? In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth’s surface. The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of […]
Is the sun radiant energy?
Is the sun radiant energy? Does the Sun produce radiant energy? Yes, the Sun produces a lot of radiant energy, which is transmitted to Earth as light. Plants convert the electromagnetic energy in sunlight into chemical energy for their food, through a process called photosynthesis. What gives off radiant energy? The term radiant energy refers […]
What are the pros and cons to oil?
What are examples of reactants?
What are examples of reactants? Examples of Reactants The wax of a candle and oxygen in air are reactants in a combustion reaction. When you burn methane gas, the reactants are methane (CH4) and oxygen in air (O2). When water forms from its elements, the reactants are hydrogen (H2) and oxygen (O2) gas. What are […]
How do you find centroid?
How do you find centroid? Centroid of a Triangle Definition: For a two-dimensional shape “triangle,” the centroid is obtained by the intersection of its medians. The centroid of a triangle = ((x1+x2+x3)/3, (y1+y2+y3)/3) To find the x-coordinates of G: To find the y-coordinates of G: Try This: Centroid Calculator. How do you find the centroid […]
What is the main function of integrated circuit?
What is the main function of integrated circuit? An integrated circuit, or IC, is small chip that can function as an amplifier, oscillator, timer, microprocessor, or even computer memory. An IC is a small wafer, usually made of silicon, that can hold anywhere from hundreds to millions of transistors, resistors, and capacitors. What are the […]
How does a photon interacts with matter?
How does a photon interacts with matter? In a pair-production interaction, the photon interacts with the nucleus in such a manner that its energy is converted into matter. The interaction produces a pair of particles, an electron and a positively charged positron. These two particles have the same mass, each equivalent to a rest mass […]
Why is energy released in a fission reaction?
Why is energy released in a fission reaction? Fission is the splitting of heavy nuclei (such as uranium) – in two smaller nuclei. This process needs less energy to ‘bind’ them together – so energy is released. The larger nuclei again needs less energy to hold it together – so energy is released. What is […]
