Explain the Theory of Isostasy.
The Theory of Isostasy states that the Earth's lithosphere floats on the semi-fluid asthenosphere, and when weight is added or removed, the lithosphere will adjust its elevation to reach equilibrium.
Types of mass wasting include creep, solifluction, rockfalls, debris flows, and landslides, each with its own characteristic features, and taking place over timescales from seconds to hundreds of years. Mass wasting occurs on both terrestrial and ______ slopes, and has been observed on Earth, Mars, Venus, Jupiter's moon Io, and on many other bodies in the Solar System.

What is the source of paleomagnetism?
The source of paleomagnetism is the alignment of magnetic minerals in rocks with the Earth's magnetic field at the time of their formation, which provides information about the past behavior of the Earth's magnetic field.
Subsidence is sometimes regarded as a form of mass wasting. A distinction is then made between mass wasting by subsidence, which involves little horizontal ______, and mass wasting by slope ______.

Mass wasting, also known as mass movement, is a general term for the movement of rock or soil down slopes under the force of gravity. It differs from other processes of erosion in that the debris transported by mass wasting is not entrained in a moving medium, such as water, wind, or ______.
