Cold weather will cause some trees to shatter by freezing the sap, because it contains water, which expands as it freezes, creating a sound like a gunshot. [1] [2] The sound is produced as the tree bark splits, with the wood contracting as the sap expands.
Hura crepitans, the sandbox tree, [2] also known as possumwood, monkey no-climb, assacu (from Tupi asaku) and jabillo, [3] is an evergreen tree in the family Euphorbiaceae, native to tropical regions of North and South America including the Amazon rainforest. It is also present in parts of Tanzania, where it is considered an invasive species. [4]
Frost crack or Southwest canker [1] is a form of tree bark damage sometimes found on thin barked trees, visible as vertical fractures on the southerly facing surfaces of tree trunks. Frost crack is distinct from sun scald and sun crack and physically differs from normal rough-bark characteristics as seen in mature oaks , pines , poplars and ...

The tree will make a sound, even if nobody heard it, simply because it could have been heard. The answer to this question depends on the definition of sound. We can define sound as our perception of air vibrations. Therefore, sound does not exist if we do not hear it. When a tree falls, the motion disturbs the air and sends off air waves.
The pressurized water boils, and this causes the geyser effect of hot water and steam spraying out of the geyser's surface vent. A geyser's eruptive activity may change or cease due to ongoing mineral deposition within the geyser plumbing, exchange of functions with nearby hot springs , earthquake influences, and human intervention.

Show me a tree exploding in a fire, and it is invariably a boiling sap explosion rending the tree (and the healthier and "greener" a tree is, the more likely it is to explode from sap flashed into steam). Anybody who's ever tossed a green log into a bonfire, and then been bombarded by embers when it explodes twenty minutes later, learns this ...
Betula nigra, the black birch, river birch or water birch, is a species of birch native to the Eastern United States from New Hampshire west to southern Minnesota, and south to northern Florida and west to Texas. It is one of the few heat-tolerant birches in a family of mostly cold-weather trees which do not thrive in USDA Zone 6 and up.
