Answer:
Explanation:
Paleomagnetism is the study of the __record of earth's__ magnetism in rocks. When magma cools, the magnetic iron-bearing minerals align themselves with the Earth's magnetic field and record__the direction__ and ___intensity__.
Paleomagnetism is branch of geophysics which studies the record of earth's history of magnetism over its history.
Iron bearing minerals such as haematite that accompanies magma formation can be magnetized as they cool to form igneous rocks. This magnetization would record the current direction of the magnetic field and its intensity. When the magma finally cools and solidifies, the record is arrested and preserved in the rock.
Answer:
Time-space compression refers to the set of processes that cause the relative distances between places (i.e., as measured in terms of travel time or cost) to contract, effectively making such places grow “closer.” The idea of a “shrinking world” is not new and, in the face of rapid advances in travel, such as the jet ...
Answer:
When discussing drought, one must have an understanding of aridity and the difference between the two. Aridity is defined, in meteorology and climatology, as "the degree to which a climate lacks effective, life-promoting moisture" (Glossary of Meteorology, American Meteorological Society). Drought is "a period of abnormally dry weather sufficiently long enough to cause a serious hydrological imbalance". Aridity is measured by comparing long-term average water supply (precipitation) to long-term average water demand (evapotranspiration). If demand is greater than supply, on average, then the climate is arid. Drought refers to the moisture balance that happens on a month-to-month (or more frequent) basis. If the water supply is less than water demand for a given month, then that month is abnormally dry; if there is a serious hydrological impact, then a drought is occurring that month. Aridity is permanent, while drought is temporary.
