Why do waves not transfer matter? A wave transports its energy without transporting matter. Waves are seen to move through an ocean or lake; yet the water always returns to its rest position. Energy is transported through the medium, yet the water molecules are not transported. Do waves transfer mass? Waves transfer energy but not […]
What are the difference between the three types of stress compression tension and shear?
What are the difference between the three types of stress compression tension and shear? Compression is the most common stress at convergent plate boundaries. Rocks that are pulled apart are under tension. Tension is the major type of stress at divergent plate boundaries. When forces are parallel but moving in opposite directions, the stress is […]
How do we use infrared waves in everyday life?
How do we use infrared waves in everyday life? Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark. The heating effect of IR can cause burns to the skin. Can deer see IR […]
Is Mid-Atlantic Ridge a normal fault?
Is Mid-Atlantic Ridge a normal fault? 2 Study Area: The Northern Mid‐Atlantic Ridge (12°N–36°N) The MAR is a slow spreading mid‐ocean ridge (2.5 cm/yr full rate) characterized by a ∼10–20 km wide axial valley bordered by normal faults and segmented by transform and nontransform offsets [e.g., Searle and Laughton, 1977; Spencer et al., 1997]. At […]
Is deceleration a physics word?
Is deceleration a physics word? Rick suggests: “Deceleration” is not actually a term in physics. It is only an English word used in common speech, meaning “a decrease in speed.” The problem with this word is that some students mistake it to mean the same as negative acceleration. Is deceleration a vector quantity? In a […]
What does a horizontal line indicate?
What does a horizontal line indicate? A horizontal line is commonly used in technical analysis to mark areas of support or resistance. A horizontal line runs parallel to the x-axis. In technical analysis, the horizontal line is typically drawn along a swing high, or a series of them, where each high in the series stopped […]
How do I identify an alluvial fan?
How do I identify an alluvial fan? Check the mouths of tributaries in larger valleys while in the field. Check topographic maps, and look for fan shaped elevation lines at the mouths of tributaries. Check soils maps for soils designated as “local alluvium.” What is the human impact of alluvial fan? Willful and continuous interference […]
Which gases is not a greenhouse gas?
Which gases is not a greenhouse gas? Examples for greenhouse gases: Carbon dioxides, Methane, Chlorofluorocarbon, sulphur dioxide. Whereas oxygen, nitrogen and argon are not examples of greenhouse gases. Is nitrogen monoxide a greenhouse gas? The direct greenhouse gases are carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4). The indirect greenhouse gases are non-methane volatile […]
What is the importance of isotopes in our daily life?
What is the importance of isotopes in our daily life? Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes. What means 2he? […]
What is a food chain in an ecosystem?
What is a food chain in an ecosystem? A food chain describes how energy and nutrients move through an ecosystem. In the food chain, energy is transferred from one living organism through another in the form of food. There are primary producers, primary consumers, secondary consumers and decomposers- all part of the food chain. How […]
