What is the difference between arid conditions and a drought? ​
Soloha48 [4]

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.

A rock differs from a mineral. While they are both solid, a mineral has a crystalline structure while a rock does not have a specific structure. Rocks are made up of different mineral structures and that is what Joseph discovered on dropping the rock, one of the component minerals in the rock. For example, a type of rock, slate may consist of feldspar, quartz among many other minerals.

What are the 2 major sources of Earth's interior heat ?
sergey [27]

The heat that remains inside the Earth from its creation and radioactive decay are its main heat sources.

The deep earth receives heat from three main sources: (1) heat left over from the planet's formation and accretion, (2) frictional heating brought on by denser core material sinking to the planet's centre, and (3) heat from radioactive element decay.

The energy produced when unstable atoms decay is known as radioactivity, and it is a substantial contributor to the Earth's heat. The main source are the radioactive isotopes of uranium-235 (235U), uranium-238 (238U), potassium-40 (40K), and thorium-232 (232Th) in the Earth's mantle.
