Answer:
A straight angle measures 180°. ... An angle can be measured using a protractor, and the angle of measure 90 degrees is called a right angle. In a right angle, the two arms are perpendicular to each other. When the right angle is divided into two equal parts each angle measures 45°.
A. Canyons and sedimentary deposits
Answer:
A. The ice has a high albedo.
Explanation:
Albedo is a measure of ‘whiteness’ or reflectivity which is also the rate at which a surface is able to reflect a percentage of solar radiation it receives. White surfaces have a higher albedo which is why Arctic and Antarctic regions with lots of ice sheets have a high albedo. They play a big role in regulating global temperatures. The larger the ice sheet cover in the antarctic and arctic regions, the more they reflect solar radiation back to space hence keeping the temperatures on earth from rising considerably.
Answer:
The correct answer is - all of the answer choices.
Explanation:
In an ecosystem, there are various organisms that are grouped in different trophic levels and groups such as producers, consumers, scavengers or decomposers based on their function and position on the food and energy chain.
The food energy is created by producers and is passed to consumers, scavengers, and decomposers of all the organisms. Energy moves in only one direction in any ecosystem. Energy is passed from producers to one trophic level or energy level, to organisms in the next trophic level.
