If the need for a strong glue arises and no modern options exist, hack your own using crushed charcoal and pine sap (=tree juice). Start by sourcing (=collecting) pine sap from the pine tree. Often you can find this sap in the form of dried clusters on the exterior of the tree. Look for wounds the tree may have suffered and collect the sap that oozes forth (=seep out) there. Next, melt the pine sap over the heat of a fire in a small metal container or in a depression(=pit) on a hot rock. While the sap is melting, crush black charcoal from the fire pit ( the black chunks, not white ash) into a fine powder. Mix the powdered charcoal into the melted pine sap — 1 part charcoal to 3 parts pine sap . As this sticky mixture cools it will harden into a very strong natural epoxy that can be used as a glue substitute (=instead). The leftover dried glue in the metal tin can be reheated later to be made pliable (=flexible) once again and used indefinitely (=with no end).

  When two air masses with different temperatures and moisture content collide, they cause atmospheric disturbances. When the warm air rises, its cooling causes water vapor to condense and the formation of clouds and precipitation. A mass of warm and light air is always forced upward, while the colder and heavier air acts like a wedge (=a piece material with a pointed edge at one end and a wide edge at the other, either pushed between two objects to keep them still). This cold-air wedge undercuts the warmer air mass and forces it to rise more rapidly. This effect can cause variable, sometimes stormy, weather. Cold Fronts These fronts occur when cold air is moved by the wind and collides (=bumps) with warmer air. Warm air is driven upward. The water vapor contained in the air forms cumulus clouds, which are rising, dense white clouds. Cold fronts can cause the temperature to drop by 10° to 30° F (about 5°-15° C) and are characterized by violent and irregular winds. Their collision ...

  Animals exist in a great variety of forms, from single-celled organisms to complex ones made of thousands of cells. The way they are classified, or divided into groups, depends to a large extent on how complex their bodies are. The two terms higher animal and lower animal are often used in this context. The higher an animal is, the more complex its internal organs are. In general, the distinguishing features of higher animals are segmentation , body cavities and some kind of skeleton . Segmentation The division of a body into separate areas, or segments , a step up in complexity from a simple undivided body. Generally, the more complex the animal, the less obvious its segments are. The most primitive form of segmentation is metameric segmentation , or metamerism . The segments ( metameres ) are very similar, if not identical. Each contains more or less identical parts of the main internal systems, which join up through the internal walls separating the segments. Such segme...

In Claughton, Lancashire, the Forterra brickworks produces 50 million bricks a year, from shale that's quarried a mile and a half away. To get that shale to the brickworks: the last aerial ropeway in the country. It uses no power, moves 300 tonnes a day. These used to be common: but now, the last one will be gone by 2036. the folks = INFORMAL people in general shale = a type of soft, grey rock, usually formed from clay that has become hard, that breaks easily into thin layers commissioned = started to work bull rail = a bar that goes from one post or support to another dusted = cleaned from dust muck = dirt gravity fed = gravity maintains the flow of material through a supply system pivot = the central point, pin, or shaft on which a mechanism turns hopper = a container for rock vital key = extremely important contractor = one that contracts to perform work or provide supplies splice = join or connect trestle = an open braced framework used to support an elevated structure...
