How does water play a role in climate? It is continuously moving above, on and below Earth’s surface, cycling among ice, liquid water and vapor. This cycling of water shapes the climate by delivering rain and snow, and it supports life on Earth. Water vapor is actually a greenhouse gas, which traps heat in the […]

What is landmass called? A landmass, or land mass, is a large region or area of land. The term is often used to refer to lands surrounded by an ocean or sea, such as a continent or a large island. In the field of geology, a landmass is a defined section of continental crust extending […]

Why does moon always face Earth? “The moon keeps the same face pointing towards the Earth because its rate of spin is tidally locked so that it is synchronized with its rate of revolution (the time needed to complete one orbit). In other words, the moon rotates exactly once every time it circles the Earth. […]

Are glass lizards dangerous? As with most lizards, the regrown tail is rarely as long as the original one. It is also usually lighter in color than the original tail, giving rise to its nicknames of joint snake. Glass lizards are nonvenomous and completely harmless to humans. Are legless lizards harmful? There are seven families […]

Does force depend on gravity? The magnitude of this force depends upon the mass of each object and the distance between the centers of the two objects. Mathematically, we say the force of gravity depends directly upon the masses of the objects and inversely upon the distance between the objects squared. What force is caused […]

What are the effects of the rotation of the earth? Effects of Rotation of the Earth The spinning of the earth on its axis causes days to turn into nights. A difference of one hour is created between two meridians which are 15 degrees apart. A change in the direction of wind and ocean currents. […]

Why do lava flows happen? Lava forms when magma erupts from a volcano. As pressure is released gases, dissolved in the magma, bubble out so the composition of lava changes. Most lava flows are formed by the eruption of hot (around 1200oC) basalt magma, (see video clip above). Where are lava flows found? They are […]

What looks like a tornado but isn t? Gustnadoes look like tornadoes, but they’re actually much smaller, weaker columns of rotating air. Plus, unlike a tornado, they’re not attached to storm clouds at all. Instead, they sometimes develop among the winds that precede a thunderstorm, and they can rise anywhere from 30 to 300 feet […]

Which continents participate in the Olympics? The rings are five interlocking rings, coloured blue, yellow, black, green and red on a white field, known as the “Olympic rings”. The symbol was originally created in 1913 by Coubertin. He appears to have intended the rings to represent the five continents: Europe, Africa, Asia, America, and Oceania. […]
