1 Igneous Rocks: form by crystallizing melted material (magma). 2  They can form either on the surface (extrusive igneous rocks), or deep in the crust (intrusive or plutonic igneous rocks). 3  Volcanoes are places where magma erupts as lava or ash.etamorphic rocks: 1  form by recrystallization of either igneous or sedimentary rocks. 2  This happens when the temperature, pressure or fluid environment change and a rock changes its form (e.g. limestone turns to marble). 3  The range of temperatures for metamophism is 150C up to the melting temperature.
1 Answer 1. Depending on the temperature in your fridge, cooked lentils will be safe to eat for 2 to 5 days when using a sealed container, filled with the cooking water. By immersing them, your lentils won't dry out and they'll be ready to use whenever you need them - just drain the amount you need.
To boil lentils, use three cups of liquid for each cup of lentils. Placed in already boiling water, lentils will be easier to digest than those that were brought to a boil with the water. When the water returns to a boil, turn down the heat to simmer and cover. Green lentils usually take 30 to 45 minutes to cook, while red lentils require 10 to 20 minutes.
