This chapter explores how groundwater reaches the Earth's surface, highlighting both natural processes and human activities. Natural occurrences include springs and geysers, while human-induced methods involve the creation of wells. Additionally, it delves into the importance of conserving groundwater, factors affecting its availability, and the relationship between groundwater and geology, including the formation of karst topography. Learn about key terms like aquifers, subsidence, and mineral deposits, as well as features associated with different geological formations.

  1. Chapter 14 Worksheets Section 1-3

  2. 14.1 While You Read: Water in the Ground • Explain the different ways groundwater can reach the surface of the earth. Give two ways that occur naturally and two ways that occur because of human activity. Humans can dig into the ground until groundwater is reached, forming an ordinary well. Wells can also be drilled into artesian formations to make artesian wells. Where the water table meets the surface, groundwater can flow out as a spring. When cracks occur in the cap of an artesian formation, artesian or fissure springs can rise through the cracks. Groundwater can be heated deep in the Earth closer to the surface in areas of recent volcanic activity. The heated water may rise to the surface as a boiling hot springs or as a geyser, or in the form of steam in a fumarole.

  3. 14.1 After You Read Type of rock or soil, climate, topography, vegetation, land use, whether land is saturated. Water that is stored in the ground. The amount of pore space between the grains of soil or rock. Particle shape and sorting The rate at which liquids pass through the pore spaces of rock. Grain size, whether or not pores are connected, presence or absence of capillary water.

  4. 14.2 Conserving Groundwater Water table deficit subsidence ponds salt water seeps into aquifer Structures replenishingsupplies pumped underground

Mineral deposits, geyserite Cavern, stalagmites and stalactites

  6. 14.3 After You Read Identify some features you would find in an area that has karst topography. Sinkholes, sinkhole ponds, lost river, underground drainage
