TEPHRA AND PYROCLASTIC ROCKS. The rapid eruption of expanding gases results in the obliteration and fragmentation of magma and rock. The greater the explosivity, the greater the amount of fragmentation. Individual eruptive fragments are called pyroclasts (fire fragments).Tephra (Greek, for ash) is a generic term for any airborne pyroclastic accumulation.Whereas tephra is unconsolidated, a pyroclastic rock is produced from the consolidation of pyroclastic accumulations into a coherent rock type.he greater the explosivity, the greater the amount of fragmentation. Individual eruptive fragments are called pyroclasts (fire fragments). Tephra (Greek, for ash) is a generic term for any airborne pyroclastic accumulation.
Test the temperature of the milk with an instant-read thermometer once the milk has begun to steam and show small bubbles. Milk is considered to be scalded once it exceeds a temperature of 180 degrees F. Select a heat-proof measuring cup that is capable of holding at least twice as much milk as you wish to heat.
Engorged breasts are a normal occurrence for many women in the first 2 to 5 days after child birth. When milk first comes in there is a flooding of lymph fluid and blood, which causes the breast tissue to swell. Breastfeed 8 - 12 times in 24 hours to prevent milk from accumulating in your breasts. 2  There may be times when you need to wake your baby for feeding. 3  Don't restrict your baby's time on the breast by limiting feeding based upon a prescribed number of minutes.
