Rantinus mengendong anaknya, yang berusia 2,5 bulan dan belum diberi nama, di posko korban gempa dan tsunami di Kecamatan Sikakap, Kabupaten Kepulauan Mentawai, Jumat (29/10/2010). Bantuan yang terlambat mengakibatkan korban tidur di lantai beralas tikar. Kebutuhan bayi juga masih sangat minim.

MENTAWAI, KOMPAS.com - Suasana duka masih menyelimuti korban gempa dan tsunami di Kepulauan Mentawai, Sumatera Barat, JUmat (29/10/2010). Mereka yang luka dan dirawat di klinik darurat sebagian besar para lanjut usia dan balita.

gunung merapi


Masyarakat di sekitar Gunung Merapi dan semua pihak diimbau tetap waspada dan bersiaga. Peringatan ini terkait aktivitas Merapi yang kembali meningkat sejak Kamis petang kemarin. Bahkan, lava pijar kembali dimuntahkan Merapi pada pukul 03.00 WIB, Jumat (29/10) dini hari. Lava pijar ini muncul di puncak Merapi selama sekitar dua jam.

Hingga siang tadi, secara sporadis Merapi terus memuntahkan awan panas yang oleh masyarakat sekitar disebut wedhus gembel. Merapi menyemburkan awan panas yang sangat pekat dengan durasi sekitar 22 menit. Mengikuti angin, awan itu mengarah ke sektor selatan di Kali Gendol, Cangkringan, Sleman, dengan jarak luncur hingga 3,5 kilometer dari puncak.

Tak urung awan panas Merapi membuat warga di kaki gunung takut, seperti penduduk Dusun Kinahrejo, Cangkringan. Mereka buru-buru membatalkan niat menengok rumah yang ditinggalkan untuk mengungsi.

Saat keluar dari kawah Merapi, suhu wedhus gembel mencapai 1.200 derajat Celsius. Ketika bergerak sejauh tiga kilometer, suhunya turun menjadi 500 hingga 600 derajat Celsius. Suhu yang sanggup melumat apa pun yang diterjangnya.

Photosynthesis Process

Photosynthesis is a Biochemical Process that occurs in plants, algae, and some bacteria, Creating the Atmospheric Oxygen and food that sustain the majority of life on Earth.

The process uses sunlight to convert water and Carbon Dioxide into Carbohydrates and Oxygen. It works into two stages : The Light Dependent Reaction and The light Independent Reaction. In Senior High School, generally known as Aerob Reaction and Anaerob Reaction.

The First stage is The Light Dependent Reaction. In this first step of Photoshnythesis, sunlight enters the first Photosystem and energizes the Chlorophyll.

The excited Chlorophyll splits water into Oxygen and Hydrogen. Meanwhile, the chlorophyll feeds electrons into a complex sequence of nearby molecules called the electron transport chain.

The freed Oxygen escapes into Athmosphere, While the freed Hydrogen is used later in The light Independent Reaction.

As electrons move along the electron transportchain, their energy make the molecule ATP, which is used by all known forms of life to fuel their cellularfunctions.

Theelectrons enter a second Photo system, get full energized by sunlight, and move along another electron transport chain to construct a molecule called NADP.

The second stage is The Light Independent Reaction. NADP combines with Hydrogen, which was freed earlier in The Light Dependent Reaction, to produce NADPH.

NADPH, ATP, and Choloroplast Enzyme called Rubisco, work together to create sugars and other Carbohydrates from Carbon Dioxide and Water in a Process calledThe Calvin Benson Cycle. It is a very complex reaction that Fixes arbon from the Athmosphere forming The Foundation of Earth’s major food chains plants directly use sugar as their food, and many other organisms eat plants to gain their stored energy.

We can also conclude that Photosynthesis is how plants use light and water to make sugar and It is created in the green parts of a plant and every animal on earth depends on it. So, Without plants we would have no food to eat or oxygen to breath.

How do seasons happen?

Seasons come to us regularly. We have probably noticed that it gets warmer in summer or dry season while it get colder in the winter or wet season. However do we know how these seasons change?

Seasons happen and change every year. This happens because the earth tilts back and forth as it goes around the sun. During the summer, the earth tilts toward the sun. It makes half of the earth hotter. this condition is what we call summer. During the other half of the year, the earth tilts away from the sun. As a result, it makes that half of the earth cooler. This cool condition is then what we call winter.

The different parts of the world have the same season at different times. In the northern half of the world , winter happens during the months of December, January and February. The regions are such North America and Europe. In the other hand, the southern half of the world have winter during the months of June, July and August.The regions are like South America and Australia. How does this difference happen? The same season happens at different times because the top and bottom halves of the earth tilt away from the sun at different times.
