1 CHAPTER 9 PHYSICS FOR JUNIOR HIGH SCHOOL IX

2 THE SUN IS A STAR A.THE SUN  The sun is the centre of solar system. The sun is one of hundret billion stars in the milky way.  The sun consist fusion reaction, it means fusion of two atom or more light atom become a new atom.  In a time, the sun will crease because mass of the sun increase and hydrogen as the main energy of the sun decrease

3 PHYSICS FOR JUNIOR HIGH SCHOOL IX THE SUN IS A STAR The Layers of the Sun:  The sun consist fusion reaction, it means fusion of two atom or more light atom become a new atom.. a.Photosphere is layer of the sun that radiate shining light make dazzle light. b.Chromospheres is thick gas layer cover photosphere and called sun’s atmosphere. c.Corona is the most outside of sun’s layers and the shape is inconstant.

4 PHYSICS FOR JUNIOR HIGH SCHOOL IX THE SUN IS A STAR The sun’s activities  Based on observation that have been taking by expert, at the photosphere layer, the sun seems in activity, such as node or sunspot, granule, and photosphere pacula, likes a prominence.  Sunspot is effect of contradict magnetic activity.  Granular photosphere is activity that caused at sun’s layer on photosphere.  At the cover of atmosphere of the sun (corona), there is gas activity that spread out strongly. It called prominence.

14 PHYSICS FOR JUNIOR HIGH SCHOOL IX THE EARTH IS A PLANET 1.Bentuk dan Ukuran Bumi  Bumi berbentuk bola agak pipih. Garis tengah bumi pada khatulistiwa adalah ,32 km, sedangkan jarak antarkutubnya ,54 km. Bumi diselimuti oleh lapisan udara yang disebut atmosfer.  Sekitar 71% permukaan bumi berupa perairan. Semua perairan, termasuk lapisan es disebut hidrosfer. Hidrosfer sangat penting dalam kehidupan hayati. 2.Gaya Tarik Bumi dan Pengaruhnya  Gravitasi atau gaya tarik diakibatkan gaya timbal balik antara massa benda-benda, misalnya antara Bumi dan Bulan.  Bumi juga memiliki gaya gravitasi. Gaya gravitasi ini menyebabkan semua benda di Bumi memiliki bobot.

15 PHYSICS FOR JUNIOR HIGH SCHOOL IX THE EARTH IS A PLANET 3.Rotation of The Earth Rotation of the earth is phenomena of the earth that rotate at its axis rotation Effect that caused by rotation of the earth : 1.Pseudo-movement of the sun. 2.Times different at meridian. 3.Day and night. 4.Wind direction deviation. 5.The earth become flattened at the poles and bloat at the equator.
