Jonathan used the following soil triangle to identify a sample of soil as sandy clay. Which description of soil likely allowed J
onathan to make this identification. A. Mostly large grains, with a sticky texture, 55% sand, 40% clay, 5% silt.
B. Mostly large grains, with a gritty texture, 45% sand, 5% clay, 45% silt.
C. Mostly small grains, with a smooth texture, 30% sand, 5% clay, 65% silt.
D. Mostly small grains, with a sticky texture, 30% sand, 50% clay, 20% silt.
Alkanes experience only dispersion forces. Dispersion forces increase with increasevin the relative molecular mass of the compounds. Hence a higher relative molecular mass implies greater dispersion forces and a greater boiling point.
Answer: An igneous rock that cools rapidly is made of really small mineral crystals.
Explanation:
The layers inside the earth are hot enough to melt a rock. The liquid or molten rock is known as magma.
When a molten rock cools and solidifies, it results in the formation of an igneous rock.
The slow cooling of magma will result in the formation of an igneous rock with large crystals. Whereas, rapid cooling of lava will result in the formation of an igneous rock with small crystals.
Thus, it can be concluded that an igneous rock that cools rapidly is made of really small mineral crystals.
