Orcas breath through their Blowholes which is located on the top of their head.
Orcas is a toothed whale and is the largest member of the Dolphin family. These large marine mammals are easily distinguished by their black and white coloration. Whales have lungs they use to get the oxygen they need by breathing air like humans. But instead of breathing through their mouth they breathe through their nostrils called blowholes. Blowholes is located on top of their heads. They can easily breathe through the blowhole without lifting their entire head out of the water. They only need to breath air from the surface once every 5 to 10 minutes. They don't need to fully come out over the water.

When all three fundamental colors are mixed through subtractive color mixing, such as with ink on paper, the outcome is black or any other dark color.
- Typically, the first two examples of mixing are explained using three primary colors and three secondary colors (colors made by mixing two of the three primary colors in equal amounts). Black will arise from subtractive mixing with all three primaries, while white will come from additive mixing with all three primaries.
- All the hues of the white light spectrum will be absorbed if the three subtractive primary color filters are added together. Each filter (or pigment) transmits (diffusely reflects) the other colors while absorbing its complementary color.

How might coastal settlement patterns change with increasing coastal erosion?
Studies on early coastal communities at high latitudes can reveal how earlier populations survived in regions with less biodiversity and more seasonality in the resources they could access.
What is coastal erosion?Coastal erosion is the process by which the water wears away land. Typically, this process includes damaging waves eroding away the shoreline (though constructive waves also contribute to coastal erosion).
On non-rocky beaches, coastal erosion creates rock formations where the shoreline has layers of rock or fracture zones with different levels of erosion resistance. Softer terrain erodes far more quickly than tougher terrain, creating structures like tunnels, bridges, columns, and pillars. The coast usually evens out over time.
Hydraulic action, abrasion, impact, corrosion by wind and water, and other factors, natural or manmade, can all contribute to coastal erosion.

explain 3 effects of faulting on the physical environment
Answer
Explain the effects of faulting on the physical environment
Besides fault scarps, faulting is also responsible for development of Block Mountains like horsts and deep elongated valleys called the grabens and the rift valleys. Faults are also known to cause deflection in the course of streams.
What is displacement in geology?
The separation between segments or points that were formerly connected or close together. On either side of the fault surface, layers of rock that have been moved by faults exhibit displacement.
Replace, supersede, and supplant are a few common synonyms for displace. Displace implies an ousting or dislodging even though all of these words mean "to put out of a usual or proper place or into the place of another."
How does geology measure displacement?
The offset between the footwall and hanging-wall cutoffs in a cross section for several rock units in a fault-related fold is measured (the displacement), and it is plotted as a function of distance along the fault surface from a specific point along the fault to create a displacement-distance profile.

What does a whale need to survive?
Whales need to develop echolocation, thick layers of blubber, improved lungs, stronger hearing, and larger arteries, among other things, to help them adapt to the ocean in order to assure their survival and well-being.
A big part of a whale's life is their blubber. Whales can stay warm and live in icy conditions because they have blubber, which would otherwise make them inhospitable. Some whales may also store energy in their blubber for use on long voyages or when food is in short supply. The blue whale migrates for up to four months at a time, during which time it survives mostly on the body fat and calories stored in its blubber.
Toothed whales may learn a lot about their surroundings by using echolocation, including how big an object is, how fast it is moving, whether it is above or below them, what direction it is travelling in, how far away it is, and if it is hollow or solid. Whales can avoid colliding with other things when they can't see their surroundings thanks to echolocation, which is very helpful in low-visibility environments.

french physicist henri becquerel discovered radioactivity in 1896, after geologists had developed the geologic time scale. how did becquerels discovery help later geologists as they refined the time scale
The discovery of radioactivity was made in 1896 by French scientist Henri Becquerel, after geologists had already created the geologic time scale. They had no prior knowledge of radiometric dating at the time, but they can now determine absolute age.
The phenomena of radioactivity is the spontaneous breakdown of energetically unstable atomic nuclei into more stable atomic nuclei. A little amount of mass is transformed to energy during the extremely exoergic, statistically unpredictable, first-order process known as radioactive decay. Alpha particles, beta particles, and gamma rays are the three most prevalent forms of radiation. Skin cannot be penetrated by alpha radiation. If alpha-emitting substances are ingested, breathed, or absorbed through open wounds, they may cause injury to people. In nature, atoms can either be stable or unstable. If the forces between the constituents of the nucleus are equal, an atom is stable. If these forces are out of balance or if the nucleus has an excessive amount of internal energy, an atom is unstable (radioactive). This process can be artificially produced by people, such as inside a nuclear reactor, but it can also occur spontaneously in nature. Depending on the particles or energy generated during the reaction, there are many kinds of radioactivity. Alpha particles, beta particles, and gamma rays are the three categories.

the dashed line on the cross section of red canyon is a fault. what relative age dating principle would be most useful in determining when an earthquake last occurred on this fault?
The purpose of relative age dating is to establish the chronological sequence of previous occurrences on Earth. The ideas of superposition and cross-cutting connections are two of the most significant of the few straightforward principles used by geologists in relative age dating.
Without necessarily determining their absolute ages, relative age dating is the science of figuring out the relative sequence of historical events (i.e., the age of an object in comparison to another) (i.e., estimated age). In geology, one stratigraphic column can be correlated with another using rock or surface deposits, fossils, and lithologies. Prior to the early 20th century discovery of radiometric dating, which offered an absolute dating method, archaeologists and geologists utilized relative dating to ascertain the ages of materials. Relative dating is nevertheless a helpful technique even though it can only tell you the order in which a set of events happened, not when they did. In certain ways, relative dating via biostratigraphy is more accurate and is the method of choice in paleontology. The main result of "relative dating" as observed in geology from the 17th century to the early 20th century was the Law of Superposition, which asserts that older strata would be deeper in a site than more recent layers.

one of the most active volcanoes in the world is found on the island of sicily. what is the name of this subduction zone composite volcano?
The island of Sicily is home to some of the world's most active volcanoes. What is the name of this composite volcano in the subduction zone: Mt. Etna is the name of the volcano on the island of Sicily.
A volcano is an aperture or vent through which lava, tephra (small rocks), and steam are released onto the surface of the planet. Days, months, or even years might pass between eruptions of volcanoes. Because of how hot it is deep below the Earth, some rocks slowly melt and turn into lava, a viscous fluid. Since magma is lighter than the surrounding solid rock, it rises and gathers in magma chambers. Some of the magma eventually surges through fissures and vents to the Earth's surface. In this instance, the fluid is lava, which is partially melted rock that is created when the Earth's mantle and crust melt. In the final stage of this heat-releasing process, the magma rises and, through volcanoes, explodes at the surface. The majority of volcanoes have a connection to plate tectonic activity. In the end, volcanic materials deteriorate and weather to form some of the most fertile soils on Earth, whose cultivation has generated an abundance of food and supported civilizations. Geothermal energy is produced by using the internal heat associated with nascent volcanic systems.
