EARTH SCIENCE The Formation of the Universe and the Solar System Jirah Joy R. Gicana Jessa Loraine M. Ramos  The dog and the bone Once there was a dog who wandered the streets night and day in search of food. One day, he found a big juicy bone and he immediately grabbed it between his mouth and took it home.  The dog and the bone On his way home, he crossed a river and saw another dog who also had a bone in its mouth. He wanted that bone for himself too. But as he opened his mouth, the bone he was biting fell into the river and sank. That night, he went home hungry.  The dog and the bone Moral of the story: what we already have, just like the greedy dog. prayer  house rules #1 Arrange your chairs, sit properly, prepare your notebook and ballpen.  house rules #2 Eyes on front.

Epoch Eon Some "periods" have their own When "eras" are grouped together, this subdivision; these geologic subdivisions will create the longest geologic are called "epochs." subdivision called an "eon."  Earth has been existing 4.543 billion years. In its early formation, life was not possible because the environment did not permit it.  However, as time went by, life flourished from microorganisms into a more complex organism. The presence of life on Earth was made possible due to the following factors or characteristics: CHARACTERISTICS OF THE EARTH THAT ARE NECESSARY TO SUPPORT LIFE  temperature It is the average kinetic energy of molecules within a material or system. It influences how quickly atoms, molecules or organisms move. CHARACTERISTICS OF THE EARTH THAT ARE NECESSARY TO SUPPORT LIFE  temperature Low temperature slows down chemical reaction and produces ice that makes liquid water unavailable. High temperature can cause break down of important biological molecules. just right to support life.

Hence it is an advantage being in this planet with a consistent temperature that supports life.

It is solid (ice) in the two poles and liquid along the equator which allows living organisms to consume it.

However, solid form of this will also hinder living organisms to use it.

Greenhouse gases like carbon dioxide (CO2) and methane (CH4) trap heat and protects our planet from freezing. CHARACTERISTICS OF THE EARTH THAT ARE NECESSARY TO SUPPORT LIFE  atmosphere ozone layer which protects all life forms from harmful radiation from the sun. This layer helps to warm the planet by day and cools it at night. CHARACTERISTICS OF THE EARTH THAT ARE NECESSARY TO SUPPORT LIFE  atmosphere The size of the planet and its distance from the sun affects its ability to hold significant amount of atmosphere. Earth has a right size and distance from the sun that permits it to have a right amount of atmosphere. The presence of gravity also helps in sustaining its atmosphere.

Earth is at right position from the sun that enables it to harness enough amount of sunlight. CHARACTERISTICS OF THE EARTH THAT ARE NECESSARY TO SUPPORT LIFE  energy Living organisms like plants and photosynthetic bacteria use light as the source of their energy. Some chemosynthetic organisms rely on chemical energy to support various biological processes CHARACTERISTICS OF THE EARTH THAT ARE NECESSARY TO SUPPORT LIFE CHARACTERISTICS OF THE EARTH THAT ARE NECESSARY TO SUPPORT LIFE  NUTRIENTS Is an essential factor used to build structure. Insufficient or absence of nutrients can impede synthesis of the different biological molecules. CHARACTERISTICS OF THE EARTH THAT ARE NECESSARY TO SUPPORT LIFE  NUTRIENTS Water, carbon and oxygen, phosphate and nitrogen cycles are some of the examples. Volcanism also helps in cycling the nutrients.

This distance enabled the Earth to get the much-needed heat and light, without which, this planet will become an ice-coated rock  CHARACTERISTICS OF THE EARTH THAT ARE NECESSARY TO SUPPORT LIFE Additional Factors: this help us survive? presence, the Earth is rotating at acomfortable 24 hour-period which also rotation would be way faster stabilized the rotation on which would make our 1 day in its axis just 4 hours. CHARACTERISTICS OF THE EARTH THAT ARE NECESSARY TO SUPPORT LIFE Additional Factors: Diversity of Life. Biodiversity creates food chains that sustain the survival and evolution of organisms. The adaptability of these biodiversity made each of the species successful in maintaining the web of life on earth. WHAT ARE THE CHARACTERISTICS OF EARTH THAT SUPPORT LIFE? HOW IMPORTANT ARE THESE CHARACTERISTICS?  Assignment 1 ) Do your worksheet number 1 - Due August 5, 2024 2) Performance Task Scheduled on August 5, 2024 assignment PERFORMANCE TASK I  References Licuanan, P.
