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 […]
Why can sound not travel through space?
Why can sound not travel through space? Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would […]

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 […]
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 […]
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? […]
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 […]
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 […]
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 […]
