Horizon A: This is the topmost layer, consisting of organic matter and mineral particles that have undergone weathering. Horizon B: This layer is characterized by the accumulation of minerals and nutrients leached from the upper horizons. Horizon C: The bottommost layer that directly overlies the bedrock, containing partially weathered rock fragments and minimal organic material.
In the C horizon of a soil, you would typically see partially weathered parent material that is not well-developed into soil. It is often composed of broken-down rock fragments with little organic matter, minerals, or nutrients. The C horizon is the least weathered and least fertile layer of the soil profile.
Composition, porosity, permeability, and particle size are used to describe different characteristics of sedimentary rocks. Composition refers to the minerals and materials present in the rock, porosity measures the amount of space between particles, permeability measures the rock's ability to allow fluids to flow through it, and particle size refers to the size of the individual grains or particles that make up the rock.
Scientists describe soil based on its texture, structure, composition, pH level, and organic matter content. These characteristics help categorize soil types and determine their suitability for different types of plant growth and environmental purposes.
Andesitic describes a rock's overall composition, referring to igneous rocks that are intermediate in composition between basaltic and granitic rocks. Andesite, on the other hand, is a specific type of fine-grained volcanic rock that falls within the andesitic composition range and is commonly found in volcanic regions such as the Andes Mountains.

Regarding the composition of ocean water, I would describe it as a homogeneous mixture, or solution.
Homogeneous refers to a mixture or substance in which the components are of the same kind or nature, without visible differences. This term is often used in chemistry to describe solutions or mixtures that are uniform in composition.

A Blastula is the usually spherical structure produced by cleavage of a zygote, consisting of a single layer of cells (blastoderm) surrounding a fluid-filled cavity (blastocoele). It is the early form of an animal embryo that develops from a morula. It is also called a blastosphere.
