## Step1<br />For question 19, we need to identify the smell that attracts camels to water in the desert. The correct answer is geosmin, which is a compound that gives the earth its distinctive smell after rain.<br /><br />## Step2<br />For question 20, we need to identify the two processes that cause sediments to stick together into a sedimentary rock. The correct answer is compaction and lithification. Compaction is the process where sediments are compressed under their own weight, and lithification is the process where sediments are converted into solid rock.<br /><br />## Step3<br />For question 21, we need to match the term "parent rock" with its definition. The correct answer is "e. a soil horizon made of slightly weathered rock". This is because parent rock refers to the original rock from which soil is formed.<br /><br />## Step4<br />For question 22, we need to match the term "eluviation layer" with its definition. The correct answer is "c. a soil horizon that is often dry and void of nutrients". This is because an eluviation layer is a layer of soil that has been leached of its nutrients and is often dry.<br /><br />## Step5<br />For question 23, we need to match the term "topsoil" with its definition. The correct answer is "b. the soil horizon containing organic matter and minerals". This is because topsoil is the uppermost layer of soil, which contains a high concentration of organic matter and minerals.<br /><br />## Step6<br />For question 24, we need to match the term "marine won" with its definition. The correct answer is "f. mineral deposits harvested from under the ocean". This is because marine won refers to mineral deposits that are harvested from under the ocean.<br /><br />## Step7<br />For question 25, we need to match the term "luster" with its definition. The correct answer is "d. can be described as glassy, pearly, or dull". This is because luster refers to the way a mineral reflects light, which can be described as glassy, pearly, or dull.<br /><br />## Step8<br />For question 26, we need to match the term "overburden" with its definition. The correct answer is "a. the layer of rock removed before mining can begin". This is because overburden refers to the layer of rock that must be removed before mining can begin.
