Equator why hotter

The presence of more air molecules and particles result in greater absorption and scattering of sun rays. Thus, these places on high latitude receive less solar energy.

More direct sunlight throughout the year leads to warmer temperatures near the equator. Sophy Owuor January 11 in Environment. Puma, Cougar, Or Mountain Lion? Bhopal Gas Tragedy.

Yet, in my classes, students rarely complete let alone comprehend the material presented in a "Read Chapter 3" type of assignment, even when it's followed by a quiz. But the vast majority of students will complete an assignment like the one presented here, which requires students to extract and record specific information from the textbook. Higher-order thinking it's not, but it is a helpful incentive to encourage students to open their textbooks and actually comprehend what is written there.

I give students practice answering questions in low-stakes ConcepTests using clickers or on-line practice quizzes before asking such questions on high-stakes exams. Here are some sample questions:. Summer days would be longer than they are now and winter days would be shorter than they are now.

On exams, I ask students open-ended essay questions Microsoft Word 4. See more Examples ». Your Account. This page first made public: Sep 15, Summary One of the most common and persistent scientific misconceptions is that Earth's seasons are caused by Earth's distance from the sun.

This activity has been extensively tested, revised and retested for more than 15 years in the Concepts in Earth and Space Sciences course for future teachers at California State University, Chico. It should work well in Earth science and astronomy courses from middle school to college level. Because this activity is designed to guide students toward discovery of the concepts, it works best if complete it before reading any explanations of or receiving any direct instruction about the causes of the seasons or why it is warmer at the equator than it is at the poles.

Other materials needed in chronological order : Per Table: Flashlight Collection of spherical objects to represent celestial bodies as follows:.

Notes on Lab Activity 1: Scale Model of the Solar System I recommend doing the outdoor activity as a whole class with student volunteers to represent each planet; choose the tallest person in the class to pace off the distances. When you get to "Earth," have the students place the moon at the appropriate distance from Earth and point out that, coincidentally, the moon and sun look the same size as seen from Earth.

The temperature difference from the pole to the equator depends on the Sun's energy and the energy retained in Earth's systems. There have been times when the Earth didn't have polar ice caps or deserts and there have been times when ice buried much of the Earth's surface.

Even small changes in Earth's energy balance impact the temperature at the equator, the poles and every place in between. The equator receives the most direct sunlight and therefore the most solar energy. The day-night temperature difference generally is greater than the temperature difference between the equator's warmest and coldest months. Elevation and weather patterns like thunderstorms influence the local equator temperatures as well. Geography controls the temperature difference between the north and south poles.

The north pole is located in ocean while the south pole lies on a continental mass surrounded by ocean. The sea water below the Arctic ice cap is slightly warmer than the ice and warms the air above. The land mass of Antarctica, however, reduces the influence of the ocean. Good luck for class project.???? I want to know the short answer why are regions close to the equator warm.
