Why are desert landscapes jagged and rocky? There is little chemical weathering to round the landscape. Lack of vegetation causes sinkholes between rock formations. The evaporation process creates angular surfaces.

A. There is little chemical weathering to round the landscape.

Explanation:

There is little chemical weathering to round the landscape in desert, primarily because there is significantly small to none water available to cause any weathering of the rocks or other structures in deserts.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
