Lab: Absorption and Radiation by Land and Water Lab Report

will give 300 point to person who completes

i got two u tell me which one is right for the rest of it i want my points

Explanation:Purpose:To compare how different materials on Earth’s surface absorb heat and to understand how the angle of insolation affects the heating of Earth’s surface Question: What factors influence the absorption of sunlight at Earth's surface? Hypothesis #1: Different materials will change temperature at different rates when exposed to the same amount of heat. This is because the different materials absorb heat at different rates. Hypothesis #2: If the angle of insolation is higher, then the temperature of the soil will be higher because it will receive more direct light. Lab Procedure: 1.Prepare for the project. a.Read through this guide before you begin, so you know the expectations for this lab. b.If anything is not clear to you, be sure to ask your teacher. 2.Open the virtual lab. 3.Compare absorption rates of materials. a.Read about why different places on Earth have different temperatures. b.Press the “?” button to learn more about absorption rate. c.Press the “Start the Lab” button to start the lab.

Original

radiative balance

incoming energy=outgoing energy

heat equator

line that connects points of equal, hottest temperatures on earth

how did the heat energy received by the cup of soil compare to the heat energy received by the cup of water?

the same amount of energy received

which cup heated more rapidly

the soil cup

which cup cooled more rapidly?

the soil cup

which is a better absorber and radiator of heat energy, soil or water?

soil

by 3:00 pm on a summer day would air be cooler over ocean water or would be cooler over the nearby land?

would be cooler over ocean water

how would the density of the air over the ocean compare to the density of air over the nearby land?

over land=hotter and less dense

over water=cooler and more dense

why does the heat equator for January bend farther into the Southern Hemisphere over the continents of South America and Africa than it bends over the ocean areas?

the land absorbs heat more

why does the heat equator move farther into the Northern Hemisphere in July than it moves into the Southern Hemisphere in January?

there's more land surface

list the sources of error and tell how each error specifically affects your results.

-lamps didn't distribute light

-sand too reflective

how do water and land surfaces differ in their abilities to absorb and radiate heat energy?

land absorbs faster and radiates faster

answer; i believe the correct answer is (crops);
