How does climate affect species distribution? Climate change is altering where species live all over the planet. With global warming, species are moving towards the poles and up elevation where temperature is lower. However, along with global climate change, the world is also experiencing massive changes in land use which may also impact where species […]

How do you find the speed of a plane? What is the speed of the airplane in still air and the speed of the wind? Velocity (against the wind) = 1650 ÷ 3 = 550 miles per hour. Velocity (with the wind) = 1650 ÷ 2.75 = 600 miles per hour. What is the speed […]

What determines the precision of a measurement? Precision of measured values refers to how close the agreement is between repeated measurements. The precision of a measuring tool is related to the size of its measurement increments. The smaller the measurement increment, the more precise the tool. What is the precision of a ruler? Precision of […]
