Sunlit zone is depth of water exposed to sunlight, trenches is a long narrow ditch.
You should learn oceanology and also geography,biology.
The order in which the changes taking place in tectonic activity in the Martinsburg and Massanutten formation is:
- Erosion of the taconian mountains providing abundant carbonate sediment of the Massanutten formation.
- Taconian mountain building and the influx of siliciclastic sediment of the upper Martinsburg formation.
- Tectonic quiescence and the deposition of lime mud on carbonate platform of the upper Martinburg formation.
- Tectonic quiescence & the deposition of lime mud on carbonate platform of the Helderberg formation.
<h3>What order did the tectonic events happen?</h3>
As a result of the erosion of the teconian mountains, there was abundant carbonate for the Massanutten formation.
Some time later, a process of tectonic quiescence led to a deposition of lime mud on the upper Martinsburg formation, and then the Heiderberg formation.

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.
Answer:
On a planimetric map, the map scale is used to convert between the distance on the map and the actual distance in real life.
