Are the layers still horizontal or are they bent Why? Answer. Answer: Figure 10.6: Rocks that were originally deposited in horizontal layers can subsequently deform by tectonic forces into folds and faults. Folds constitute the twists and bends in rocks. How is horizontal unconformity formed? An angular unconformity is an unconformity where horizontally parallel strata […]
Is 1500 watts a lot of electricity?
Is 1500 watts a lot of electricity? Most electric heaters use 1,500 watts, but some are slightly less or slightly more. Since 1,000 watts equals 1 kilowatt, that means your heater uses 1.5 kilowatts of power. However, your electric bill is measured in kilowatt hours, which is the amount of energy used while running a […]
Who has proved that oxygen evolved in photosynthesis comes from water?
Who has proved that oxygen evolved in photosynthesis comes from water? Cornelius van Niel Which light range is most effective in photosynthesis? The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the […]
What causes resistance in a wire?
What causes resistance in a wire? The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance. The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. […]
How do you solve Vo?
Do forces have direction?
Do forces have direction? A force is a vector quantity. As learned in an earlier unit, a vector quantity is a quantity that has both magnitude and direction. Because a force is a vector that has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow. […]
What is the main cause of ozone depletion?
What is the main cause of ozone depletion? Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone’s ultraviolet radiation-absorbing capacity. Is inhaling ozone bad? Whether in its pure […]
What muffles sound the best?
What muffles sound the best? The best types of surfaces for absorbing sounds are ones with jagged surfaces and hollow recesses within (much like a sponge or cardboard). The proper object captures the sound waves and bounces them around within the object until the vibrations dwindle. Does Styrofoam deaden sound? Polystyrene foams such as Styrofoam […]
What do we call a ramp and ladder combined?
What do we call a ramp and ladder combined? A wedge is a simple machine that is made of two inclined planes together. Inclined planes don’t move, but wedges do. An axe is an example of a wedge. Inclined planes are simple machines used to make work easier. Ramps, ladders, and staircases are all inclined […]
What are the six main structures of the central nervous system?
What are the six main structures of the central nervous system? These include structures such as the frontal and temporal lobes, the thalamus, the cerebellum, the putamen, mamillary bodies and fornix, and a convolution above the corpus callosum known as the cingulate gyrus. What are the different types of neurons of the central nervous system? […]
