Usually ice is the phase known as ice I < sub > h </ sub >, which is the most abundant of the varying solid phases on the Earth's surface.

Usually, aircraft wings have various devices, such as flaps or slats that the pilot uses to modify the shape and surface area of the wing to change its operating characteristics in flight.

Usually observational astronomy is considered to occur on Earth's surface ( or beneath it in neutrino astronomy ).

Usually it is the more widely spread species that fare better in extinction, and hence this unusual pattern could be explained by a GRB, which would probably devastate creatures living on land and near the ocean surface, but leave deep-sea creatures relatively unharmed.

Usually, within the lower atmosphere ( the troposphere ) the air near the surface of the Earth is warmer than the air above it, largely because the atmosphere is heated from below as solar radiation warms the Earth's surface, which in turn then warms the layer of the atmosphere directly above it, e. g., by thermals ( convective heat transfer ).

Usually this occurs when the dust devil is not moving fast enough ( depletion ) or begins to enter a terrain where the surface temperatures are cooler, causing unbalance.

Usually, permafrost will remain discontinuous in a climate where the mean annual soil surface temperature is between.

Usually, the term sky is used from the point of view of the Earth's surface.

; Progressive Burn: Usually a grain with multiple perforations or a star cut in the center providing a lot of surface area.

; Neutral Burn: Usually a single perforation ; as outside surface decreases the inside surface increases at the same rate.

Usually ( but not always ) triangular, polygons arise when an object's surface is modeled, vertices are selected, and the object is rendered in a wire frame model.

Usually, the surface of the track is almost flush with the inclined plane's surface.

Usually insulators, e. g., substances that do not conduct electricity, are good at both generating, and holding, a surface charge.

Usually, the comb is used to engrave a cross-cut pattern into the wax to create a tackier surface.

Usually, red ants will escort the newly emerged butterfly to the surface, taking it to a low plant or shrub nearby.

Usually, the term refers to a dedicated area that has been provided with a durable or semi-durable surface.

Usually has some sort of ventilation to prevent sweat from building up inside the goggles and fogging the surface.

Usually roughly translated as ' sealed earth ', the meaning of ' terra sigillata ' is ' clay bearing little images ' ( Latin sigilla ), not ' clay with a sealed ( impervious ) surface '.

Usually thigmotropism occurs when plants grow around a surface, such as a wall, pot, or trellis.

Usually, these flights are no more than short trips above the surface, but they can be a few meters high.

Usually insulators, e. g., substances that do not conduct electricity, are good at both generating, and holding, a surface charge.

Usually, the key decision-makers in the college or university — especially if it was a private university — joined forces to, in effect, collude with the faculty member accused ; to protect not him necessarily but the reputation of the university, and to keep information from surfacing in a way that could protect other women.

" Richardson calls it " part of a tradition of apocalyptic literature that began in the 1870s " including The War of the Worlds: " Usually, this literature shows an England destroyed by alien forces, but in Collier's novel, set in Hampshire in 1995, England has been destroyed by its own vices — greed, laziness, and an overwhelming bureaucracy crippled by its own committees and red tape.

Usually these troops embody a more elite status than other imperial forces, including the regular armed forces, and maintain special rights, privileges and traditions.

Usually the amount of supplies being sent north was barely adequate to supply the forces in place.

Usually, a smaller adhesive bandage can be placed over the wound site after the gauze is removed if the wound is slow to heal.

Usually coronal loops lasting for long periods of time are known as steady state or quiescent coronal loops, where there is a balance in loop energy sources and sinks ( example ).

Usually the energy is turned into heat, for example the heat generated by friction.

Usually this occurs in a transmission electron microscope ( TEM ), although some dedicated systems exist which enable extreme resolution in terms of energy and momentum transfer at the expense of spatial resolution.

Usually, a young star will ionize part of the same cloud from which it was born although only massive, hot stars can release sufficient energy to ionize a significant part of a cloud.

Usually, the principle of conservation of energy is included.

Usually the absorbed solar radiation is converted to thermal energy, causing an increase in the object's temperature.

* Temperature: Usually conducting a reaction at a higher temperature delivers more energy into the system and increases the reaction rate by causing more collisions between particles, as explained by collision theory.

Usually the tube is praised for simplicity, but for precision measurements of charged low energy particles the electric and the magnetic field in the flight tube has to be controlled within 10 mV and 1 nT respectively.

Usually, the energy content and material usage of the product being packaged are much greater than that of the package.

* Usually operated at lower pressure than other types of pressurised irrigation, reducing energy costs.

Usually, the total mechanical energy after the collision is smaller than the initial total mechanical energy and the lost mechanical energy is converted into heat.

Usually energy star fans hold the distinction of being more energy efficient ( 50 %), have lower price tags, and save a lot of money on energy savings.

Usually the dependency is given for the kinetic energy itself depending on the power of the velocity.

Usually, only one cell of a memory is affected, although high energy events can cause a multi-cell upset.

* gun stick: Usually portrayed as a variable discharge energy weapon.

Usually, photovoltaic ( PV ) cells contained in solar panels convert the sun's energy directly into electric energy.

Usually, the goal of demand side management is to encourage the consumer to use less energy during peak hours, or to move the time of energy use to off-peak times such as nighttime and weekends.

Usually this energy is supplied by charge transfer between the guest and the host solid, i. e., redox.
