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.

what term describes continental drift? flora radiometric dating laurasia fauna gondwana plate tectonics pangaea
The concept of continental drift has been incorporated into the science of plate tectonics, which examines how continents move while riding on lithosphere plates. Abraham Ortelius initially proposed the idea that continents might have "drifted" in 1596.
One of the earliest hypotheses put up by geologists for how continents might migrate through time is called continental drift. The science of plate tectonics has now supplanted the theory of continental drift. The scientist Alfred Wegener is most closely connected with the concept of continental drift. Plate tectonics over millions of years produced continental drift. Additionally, plate tectonics clarified how the movement of the plates causes earthquakes and volcanoes, as well as how the collision of continents produced vast mountain ranges. According to the idea of plate tectonics, the land masses of the Earth are constantly shifting. Alfred Wegener was the first to recognize that Earth's land masses are in motion; he dubbed this continental drift. Here, he is seen in Greenland. According to the encyclopedic entry on continental drift in the National Geographic Society Resource Library, "Continental drift describes one of the early ways geologists believed continents moved over time. The science of plate tectonics has now supplanted the theory of continental drift.

Where do glacial ice sheets exist today?Most of the world's glaciers exist in the polar regions, in areas like Greenland, the Canadian Arctic, and Antarctica. Glaciers also can be found closer to the Equator in some mountain regions. The largest glaciers are continental ice sheets or ice caps, only Antarctica and Greenland have massive amounts of ice (> than 50,000 square kilometers 12 million acres).Continental Glaciers are a type of glacier found in Antarctica. Continental glaciers are large, slow-moving ice sheets that cover a portion of a continent, such as Antarctica. Antarctica is engulfed in sea ice during the winter, resulting in months of darkness.

Laurasia is the name given to the northernmost of the two large continents formed by the breakup of Pangaea.
Laurasia and Gondwana were the 2 significant landmasses that comprised the Pangaea supercontinent between 335 and 175 million years ago (Mya). Laurasia was the northernmost of the two.
It split from Gondwana at the breakup of Pangaea between 215 and 175 Mya (beginning in the late Triassic period), drifted north just after split, and eventually dissolved around 56 Mya with the onset of the North Atlantic Ocean. Asia and Laurentia are combined in the name.

Geoscientists calculate that for every km drilled crust of The earth, the temperature rises 15 degrees Fahrenheit and the pressure rises at a rate of about 7,300 pounds per sqr inch.
The temperature at the core of the crust is around 1000°C, around 3500°C at the bottom of the mantle, and around 6,000°C at the center of the Earth.

Adaptive radiation is responsible for the diversity of Galapagos finches. Their beaks have altered in size and form during evolution, allowing them to adapt to a variety of diets: some species primarily consume animals, while others prefer seeds or plants; some forage in trees, while others do it on the ground.

Do sea urchins like clean water?
In public aquariums, sea urchins are used as indicator organisms to determine if the system is working properly. This is due to their "pickiness" about water quality. If the water becomes contaminated, sea urchins will be the first to exhibit signs of stress, such as spines laying down or falling off.
Aristotle's lantern is a structure used by sea urchins to eat. It is made up of five hard plates that form a beak shape. They scrape algae off rocks with their beak-like mouth. Because scraping can wear down the plates, sea urchin teeth grow to replace them. Their mouth is on the underside of their body, and any waste is expelled through the anus at the top of the animal.
Sea urchins tend to congregate in colder, offshore waters, but they will occasionally venture into shallower waters in search of food. The New England green sea urchin is frequently found in tide pools and below the low-tide line. They also tend to avoid bright light. Their tests can reach a size of three or more.

The energy transfer occurring at each lettered area is:
A. Conduction B. Radiation C. Convection What are types of energy transfers?Heat energy is transferred through the mechanism of conduction when nearby atoms or molecules collide. In solids and liquids, where particles are more closely spaced, conduction happens more easily than in gases, where particles are more widely spaced. This is why A is conduction.
Heat waves are created during the radiation heat transfer process and may be absorbed, reflected, or transmitted through a cooler substance which is why the transfer of heat by fire is radiation.
Convection is the movement of fluid that allows heat to move from one location to another. Convective heat transfer combines the processes of conduction and advection, although being frequently mentioned as a separate type of heat transfer.
