The one that is blue is a hotter star
When studying the temperature of a star, the scientists first look for color. If the color is more reddish, it’s cooler; if it’s yellow/orange, it is a warmer star; and if it’s a blue star, it’s a hot star
Answer:
All dinosaur fossils found by archeologists have been found a few centimeters below the iridium layer. So, the possibility of finding dinosaur fossils above the iridium layer is very slim.
Explanation:
Over 65 million years ago, dinosaurs roamed the earth but were canceled out as a result of an extraterrestrial impact on the earth's crust. Research proved that an asteroid brought the end of dinosaurs as the element iridium was found in the earth (since iridium is abundant in asteroids and not the earth's crust).
Records of fossils found have been between 13 to 60 centimeters below the iridium or the K-T boundary as it is called.
Perimeter = 3x. Area = x^2 * sqrt(3)/4. Explanation of area:. You can divide an equilateral triangle into 2 right triangles, each with a common side we will call y.. Area = area of first right triangle + area of second right triangle = (x/2)*y/2 + (x/2)*y/2 = xy/2. Now: y^2 + (x/2)^2 = x^2 so y…
Answer: Extreme heat and pressure from deep within Earth cause changes to the rocks appearance, structure, and composition.
Explanation:
Remember!
- Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles/sediments.
- Igneous rock is formed through the cooling and solidification of magma or lava
- Metamorphic rocks are changed by heat and pressure

Explanation:
Thermal energy usually flows from an object that has a higher temperature to an object with a lower temperature. Since the whales are from Florida’s warmer waters and they can generate their own body heat since they are warm-blooded, more thermal energy would move from the whale into its environment in cooler waters.
