1. Groundwater is __ a Water from magmatic sources that accumulates underground b Water that has always been underground c Precipitation that accumulates underground d None of the above

## Step 1<br />Groundwater is the water found underground in the cracks and spaces in soil, sand, and rock. It is stored in and moves slowly through geologic formations of soil, sand, and rocks called aquifers.<br /><br />## Step 2<br />The options provided in the question are:<br />a. Water from magmatic sources that accumulates underground<br />b. Water that has always been underground<br />c. Precipitation that accumulates underground<br />d. None of the above<br /><br />## Step 3<br />Option a is incorrect because groundwater is not from magmatic sources. Magmatic sources refer to molten rock beneath the Earth's surface, which is not related to groundwater.<br /><br />## Step 4<br />Option b is the correct answer. Groundwater is water that has always been underground, which is the definition of groundwater.<br /><br />## Step 5<br />Option c is incorrect because groundwater is not precipitation that accumulates underground. Precipitation refers to any form of water, such as rain, snow, sleet, or hail, that falls from the atmosphere and reaches the ground. Groundwater is not precipitation but is formed from precipitation that infiltrates the ground.<br /><br />## Step 6<br />Option d is incorrect because there is a correct answer among the options provided.
