Weather front areas of precipitation help determine the frontal type and location. There are two different meanings used within meteorology to describe weather around a frontal zone. The term "anafront" describes boundaries which show instability, meaning air rises rapidly along and over the boundary to cause significant weather changes. A "katafront" is weaker, bringing smaller changes in temperature and moisture, as well as limited rainfall. A cold front is located at the leading edge of the temperature drop off, which in an isotherm analysis shows up as the leading edge of the isotherm gradient, and it normally lies within a sharp surface
Word sort Students do not need to have strong phonics skills in order to engage in sound sorts. This can be a beginning phonemic awareness activity because students need only to identify the sound in order to complete the sort. Letter knowledge is not required, and phonemic development can mature as students do acquire more print knowledge. Picture sorts are one component of word study and are used to help beginning readers develop Concept of Word, phonological awareness, and phonics. Picture sorts most often begin with focusing on initial sound (single consonant, digraphs, or blends). By using picture sorts teachers are able
