Any two polygons are similar if their corresponding angles are congruent and the measures of their corresponding sides are proportional: In the figure above the ratio or the scale factor of the quadrilateral to the left versus the quadrilateral to the right is ½.
Unit and measurement
One g is the force per unit mass due to gravity at the Earth's surface and is the standard gravity (symbol: gn), defined as 9.80665 metres per second squared, or equivalently 9.80665 newtons of force per kilogram of mass.
A.) Earthquake waves. Certain waves cannot go through Earth's core so scientists can kind of determine what the core is made of based on that.
Answer:
A working geographic information system (GIS) integrates five key components :
hardware, software, data, people, and methods.
erosion is to soil/rock; corrosion is to metals
erosion is by natural forces (wind, water), corrosion is by chemical
erosion is extremely slow over many years; corrosion is still slow but typically faster than that
weathering = natural force
earth's surface = soil/rock
