Chen is testing the friction of three surfaces. he pushes the same ball across three different surfaces with the same force and measures the distance of each ball. the ball moved ten inches across surface 1, six inches across surface 2, and fifteen inches across surface 3.

which could most likely describe the three surfaces?

a> surface 1 is ice, surface 2 is gravel, and surface 3 is blacktop.
b> surface 1 is gravel, surface 2 is ice, and surface 3 is blacktop.
c> surface 1 is blacktop, surface 2 is gravel, and surface 3 is ice.
d> surface 1 is blacktop, surface 2 is ice, and surface 3 is gravel.

Hannah is writing a report on how albedo affects the global climate. she’s proofreading her passage for any factual errors. which sentence must hannah correct before submitting her report? earth receives energy from the sun. this energy drives many of the processes on earth, including its climate. some part of this energy is reflected by earth’s surface. we use the term albedo to describe the reflected energy. albedo of an object is the ratio of the reflected radiation to the total radiation reaching the object. a value of 0 means no energy is absorbed by the object, whereas a value of 1 means that all of the energy is absorbed. in this way, the albedo of an object can influence earth’s atmospheric temperature.
