Full solutions for BSCS Biology: A Molecular Approach | 9th Edition
A slow motion of Earth’s axis that traces out a cone over a period of 26,000 years.
A recording barometer.
A pass between mountain valleys where the headwalls of two cirques intersect.
A theory that originally proposed that the continents are rafted about. It has essentially been replaced by the plate tectonics theory.
The transfer of heat by the movement of a mass or substance. It can take place only in fluids.
A steep-sided inlet of the sea formed when a glacial trough was partially submerged.
A fountain of hot water ejected periodically.
Seafloor sediments consisting of minerals that crystallize from seawater. An important example is manganese nodules.
Mudflows on the slopes of volcanoes that result when unstable layers of ash and debris become saturated and flow downslope, usually following stream channels.
A phenomenon, sometimes associated with earthquakes, in which soils and other unconsolidated materials containing abundant water are turned into a fluid-like mass that is not capable of supporting buildings.
The apparent shift of an object when viewed from two different locations.
The gravitational disturbance of the orbit of one celestial body by another.
A variable radio source of small size that emits radio pulses in very regular periods.
A thin coating of ice on objects produced when supercooled fog droplets freeze on contact.
A local wind blowing from the sea during the afternoon in coastal areas.
The speed at which a particle falls through a still fluid. The size, shape, and specific gravity of particles influence settling velocity.
The period of Earth’s rotation with respect to the stars.
Wind-generated waves that have moved into an area of weaker winds or calm.
The end moraine marking the farthest advance of a glacier.
Zone of fracture
The upper portion of a glacier consisting of brittle ice.
