6. (a) i. Gastropods have a spiral shell and they move using a muscular foot.ii. Rapid burial and right conditions for preservation are necessary for fossilization.(b) i. Hardness is the resistance of a mineral to scratching.ii. Specific gravity is the ratio of the weight of a mineral to the weight of an equal volume of water.(c) i. Gneiss has a banded texture and is composed of minerals such as quartz, feldspar, and mica.ii. Marble has a crystalline texture and is composed of the mineral calcite.
Explicação
## Step 1The first part of the question asks for two characteristics of gastropods. Gastropods are a type of mollusk that includes snails and slugs. They are known for their unique characteristics such as their spiral shells and their ability to move using a muscular foot.## Step 2The second part of the question asks for two conditions necessary for fossilization. Fossilization is the process by which the remains or traces of an organism are preserved in the Earth's crust. For fossilization to occur, the organism must be quickly buried to prevent decay, and the conditions must be right for the preservation of the organism's structure.## Step 3The third part of the question asks for the definition of hardness and specific gravity in the context of minerals. Hardness is a measure of how resistant a mineral is to scratching, while specific gravity is a measure of the density of a mineral compared to the density of water.## Step 4The fourth part of the question asks for the texture and mineralogy of Gneiss and Marble. Gneiss is a metamorphic rock with a banded texture and is composed of minerals such as quartz, feldspar, and mica. Marble is a metamorphic rock with a crystalline texture and is composed of the mineral calcite.
