Chocolate lava cake smothered in chocolate sauce. Molten chocolate cakes characteristically contain five ingredients: butter, eggs, sugar, chocolate, and flour. [3] The butter and chocolate are melted together, while the eggs are either whisked with the sugar to form a thick paste, producing a denser pastry, or separated, with the white whipped into a meringue to provide more lift and a ...
Vesicular texture is a volcanic rock texture characterized by a rock being pitted with many cavities (known as vesicles) at its surface and inside. [1] This texture is common in aphanitic, or glassy, igneous rocks that have come to the surface of the Earth, a process known as extrusion. As magma rises to the surface the pressure on it decreases ...
Scoria differs from pumice, another vesicular volcanic rock, in having larger vesicles and thicker vesicle walls, and hence is denser.The difference is probably the result of lower magma viscosity, allowing rapid volatile diffusion, bubble growth, coalescence, and bursting.
Phaneritic rock: Anorthosite from the Stillwater Igneous Complex (Neoarchean; Montana) Igneous textures include the rock textures occurring in igneous rocks.Igneous textures are used by geologists in determining the mode of origin of igneous rocks and are used in rock classification.
The texture of volcanic rocks, including the size, shape, orientation, and distribution of mineral grains and the intergrain relationships, will determine whether the rock is termed a tuff, a pyroclastic lava or a simple lava. However, the texture is only a subordinate part of classifying volcanic rocks, as most often there needs to be chemical ...
A sponge (/ ˈ s p ʌ n dʒ / SPUNJ) is a cleaning aid made of soft, porous material. Typically used for cleaning impervious surfaces, sponges are especially good at absorbing water and water-based solutions.
A lamington is an Australian cake made from squares of butter cake or sponge cake coated in an outer layer of chocolate sauce and rolled in desiccated coconut.The thin mixture is absorbed into the outside of the sponge cake and left to set, giving the cake a distinctive texture.
Magma rich in silica and poor in dissolved water is most easily cooled rapidly enough to form volcanic glass. As a result, rhyolite magmas, which are high in silica, can produce tephra composed entirely of volcanic glass and may also form glassy lava flows. [2] Ash-flow tuffs typically consist of countless microscopic shards of volcanic glass. [3]
