Solutions for Chapter 9: The Family Of Stars
Full solutions for Foundations of Astronomy | 11th Edition
The scientific study of climate.
A form of condensation best described as a dense concentration of suspended water droplets or tiny ice crystals.
A fault in which the movement is parallel to the dip of the fault.
A sedimentary rock formed of material deposited from solution by evaporation of water.
Scratches and grooves on bedrock caused by glacial abrasion.
A concentration of heat in the mantle capable of producing magma, which in turn extrudes onto Earth’s surface. The intraplate volcanism that produced the Hawaiian Islands is one example.
The nuclear reaction in which hydrogen nuclei are fused into helium nuclei.
A piece of one rock unit contained within another. Inclusions are used in relative dating. The rock mass adjacent to the one containing the inclusion must have been there first in order to provide the fragment.
Varieties of the same element that have different mass numbers; their nuclei contain the same number of protons but different numbers of neutrons.
A cloud that forms below a height of 2,000 meters.
A ridge of till formed when lateral moraines from two coalescing alpine glaciers join.
The layer of the atmosphere immediately above the stratosphere and characterized by decreasing temperatures with height.
Monthly mean temperature
The mean temperature for a month that is calculated by averaging the daily means.
A variable star that pulsates in size and luminosity.
A telescope that concentrates light from distant objects by using a concave mirror.
A mechanical weathering process characterized by the splitting-off of slablike sheets of rock.
Any weathering process that tends to produce a spherical shape from an initially blocky shape.
Parallel layers of sedimentary rock.
A coast with a form that is largely the result of the partial drowning of a former land surface either because of a rise of sea level or subsidence of the crust or both.
Wind-generated waves that have moved into an area of weaker winds or calm.
