How many types of tundra are there? two types Where does the name tundra come from? (The word “tundra” derives from the Finnish word tunturia, meaning barren or treeless hill.) Instead, the tundra has patchy, low-to-ground vegetation consisting of small shrubs, grasses, mosses, sedges, and lichens, all of which are better adapted to withstand tundra […]
What do gas bubbles in lava form?
What do gas bubbles in lava form? Gas bubbles formed and rose to the surface of lava which flowed freely on the surface of a young Earth. As the lava gradually solidified to form rock, these bubbles were trapped inside, forming spaces inside the rock called vesicles. What makes some magma explosive? Explosive eruptions If […]

How do you find the distance between two parallel lines in linear algebra?
Is period of pendulum proportional to length?
Is period of pendulum proportional to length? Thus, T=2π√Lg T = 2 π L g for the period of a simple pendulum. This result is interesting because of its simplicity. The only things that affect the period of a simple pendulum are its length and the acceleration due to gravity. The period is completely independent […]

What is the relation between wavelength and refractive index?
What is the relation between wavelength and refractive index? The refractive index can be seen as the factor by which the speed and the wavelength of the radiation are reduced with respect to their vacuum values: the speed of light in a medium is v = c/n, and similarly the wavelength in that medium is […]
