An area of constant high or low pressure that encircles the earth is called?
This is sooo stu
Earth doesn't have one continuous, constant atmospheric pressure, it varies both spatialy and temporally. Assuming you're talking about the atmospheric pressure at the Earth's surface, the "standard" atmospheric pressure is 1000 millibars (mb), however pressures can range anywhere from ~875 mb (in intense low pressure areas such as the center of tropical cyclones) to ~1080mb.
The force that the planet Earth applies on an object(the force is also called weight) depends on the mass of the object. It is not constant. The formula is: Weight = mass x acceleration due to gravity Acceleration due to gravity has a constant value on Earth: 9.81 m s-2 However, it is not constant everywhere in the universe. It depends on the planet you are on. Mass, however, is constant.
Well, first off, heat rises. But that is only part of the equation. The farther down to the core of Earth you go the more pressure buildup there is. So the magma which is underneath the ground is under constant pressure from the heat buildup and the Earth\'s natural pressure. When a hole opens up the the magma will relieve pressure by moving to the area of least resistence. Viola! Volcano creation.
If an orbiting shuttle follows the curve of the Earth's surface as it moves at a constant speed is what?
Latitude: Lines of constant latitude are called 'parallels', because they are the circles that define the outlines of parallel planes, like slices of the earth cut with the knife lying down. Longitude: Lines of constant longitude are called 'meridians' and are not parallel. They all converge at the North and South Poles, and divide the earth into pieces like the sections of an orange.
