Pre-Reading Activity Workbook Chapter 3 ± ± ± The word of science has its own language. If you don’t know what the words mean, you will never be able to understand the concepts that result from scientific discoveries. Formal Definition : a term, a class word, one or more limiting features

Exercise 1 : Dissecting Terms ± Term : the word that is being defined Exercise 1. ± ± Following terms were created by combining two simpler words. Give the meanings of each part of the term. Try to deduce the meaning of the whole term. Note that some terms contain more than one separate word.

1. Groundwater Ground ☞ ± the surface of the earth Water ± clear thin liquid from clouds as rain the water that is beneath Earth’s surface ☞ ± Groundwater ☞

2. Sinkhole Sink ☞ Hole ± ☞ Sinkhole ☞ ± ± disappears below the surface of a mass of water a hollow space in something solid, with an opening on one side A circular depression when the roof of an underground cavern or mine collapses

Exercise 2&3 : Class Words ± 2. Class Word : the category to which a term belongs ± 3. General/Specific/Repetitive Exercise 2 & 3 ± Choose a class word for the terms. ± You can choose from the following list. ± Decide whether the CW is G/S/R.

Exercise 2, 3 General/Specific/Repetitive a surface a cavity a layer a topography an ability(a characteristic) an ability. 1. Permeability is 2. Water table is a surface. 3. Artesian formation is a layer. (S) a cavity. (S) 4. A cavern is 5. Karst topography is a topography. (R) (G) (S)

Exercise 4 : Limiting features ± Limiting Feature : a word or phrase that distinguishes the term from other members of its class ± Exercise 4. ± Rewrite the sentences to form complete definitions. You can choose limiting features from the list. ±

Exercise 4 of underground water / upper / lower of a rock or sediment to let fluids pass through its open spaces, or pores of permeable rock sandwiched between two layers of impermeable rock and exposed at the surface

Exercise 4 1. Permeability is the ability of a rock or sediment to let fluids pass through its open spaces, or pores. upper 2. Water table is the surface of underground water. The upper boundary of the zone of saturation.

Exercise 5 : Dissecting a Definition List the term, the class word, and all of the limiting features. 1. Artesian formation is a sloping layer of permeable rock sandwiched between two layers of impermeable rock and exposed at the surface. Artesian formation Term : a layer of rock Class word : a sloping ~ Limiting features :

Exercise 5 : Dissecting a Definition 2. Irregular topography caused by the chemical weathering of limestone or other soluble rock by groundwater is called karst topography. Term : Class word : Karst topography Limiting features : topography Irregular topography~
