Answer:
Explanation:
Most limestones actually start as calcium carbonate mud or shells precipitated by organisms in reefs or shallow shelf regions - the biosphere. Over time, the limestone is broken down into its chemical parts and may come back to the surface as volcanic CO2 (in the atmosphere).
Answer:
More frequent and severe weather
Higher temperatures are worsening many types of disasters, including storms, heat waves, floods, and droughts. A warmer climate creates an atmosphere that can collect, retain, and drop more water, changing weather patterns in such a way that wet areas become wetter and dry areas drier.
The atmospheric pressure conditions for a 50+ dBZ range differs from small to heavy hails.
Explanation:
dBZ refers to decibel relative to Z used in weather radar most of the times, in order to compare the reflection factor (Z) of a weather radar signal reflected off a remote object to the return of a droplet of rain with a diameter of 1 mm.
dBZ is a logarithmic dimensionless technical unit, at 55 dBZ and above, most storms have hail which can throw off the rainfall rate because hail has a higher reflection.
Generally above 50 dBZ range the intensity varies accordingly for every 5 points. Such as small hail to moderate hail and from moderate to heavy hail.
Therefore the atmospheric pressure conditions differs from rains to hails.
The correct answer is option (a). Parent material
The soil horizon refers to distinct layers of the soils, which are parallel to one another, but have a different composition from the layer present above and below to it.
The soil horizon can be divided into four different layers. First one is organic layer, which is the topmost layer, below this layer second layer of topsoil is present. Below top soil, subsoil is present. Below subsoil, the bottom most horizon parent material is present.
