What rocks is coarse grained?
What rocks is coarse grained? Coarse grain varieties (with mineral grains large enough to see without a magnifying glass) are called phaneritic. Granite and gabbro are examples of phaneritic igneous rocks. Fine grained rocks, where the individual grains are too small to see, are called aphanitic. Basalt is an example. What are the most common […]

What is the largest type of tephra?
What is the largest type of tephra? All explosive volcanic eruptions generate tephra, fragments of rock that are produced when magma or or rock is explosively ejected. The largest fragments, blocks and bombs (>64 mm, 2.5 inches diameter), can be expelled with great force but are deposited near the eruptive vent. How do you protect […]
Which of the following will increase the energy of a photon?
Which of the following will increase the energy of a photon? The energy of the photon depends on its frequency (how fast the electric field and magnetic field wiggle). The higher the frequency, the more energy the photon has. As the frequency of a photon goes up, the wavelength () goes down, and as the […]

Which is the correct expression for Half-Life?
Which is the correct expression for Half-Life? The time required for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life, T1/2, and the decay constant is given by T1/2 = 0.693/λ. What is the half-life for uranium 238? about 4.5 billion years How dangerous is […]
