FACTORS MAKE PLANET EARTH HABITABLE.pptx

These factors interact in complex ways to create a habitable environment on Earth. The unique combination of these conditions makes our planet an oasis of life in the cosmos and underscores the significance of preserving and protecting the delicate balance that sustains life on Earth.

1. RECALL: • What do we call to a giant cloud and gas in space that can take many different forms and shapes? • What do you call to the massive star explosion? • Can you name the eight planets in our solar system?

2. Video presentation:

3. Let us answer the Following: • What is the title of story? • Who are the characters of the story? • What was Goldilocks looking for in the bears’ house? • Why did Goldilocks want something that was 'just right'? • what is common among the choices made by the goldilocks?

4. GOLDILOCK ZONE According to NASA: The standard definition for a habitable planet is one that can sustain life for a significant period; based on our solar system, life requires liquid water, energy, and nutrients. A "habitable zone" is the region around a star where planets can receive the perfect amount of heat to maintain liquid water on their surfaces Sellers Exoplanet Environments Collaboration (SEEC).

6. Learning Objectives: Identify and explain the factors that make Earth unique and habitable 2. Explain the different factors that make Earth unique and habitable 3. Recognize the factors that make Earth habitable and appreciate important value and protect our natural environment.

7. EARTH The third planet from the sun and fifth largest in the solar system A terrestrial planet located in the Goldilock Zone ( habitable Zone) Has unique physical and chemical characteristic compare to other neighboring planets The only habitable planet know in the solar System that can support Life.

8. Group Activity Each group will brainstorm and share their initial thoughts on factors that make planet Earth habitable Each group will create a list of the ideas they came up with during their brainstorming session. Then, each group will organize their ideas into a mind map format that visually represents the factors that contribute to Earth's habitability. Each group will use paper and markers or digital tools for this task. Each group present their findings. Each group will do the task for 15 minutes:

10. Factors Makes the Planet Earth Habitable

11. Temperature Influences how quickly atoms & molecules move Life seems limited to a temperature range of -15oC to 115oC. In this range, liquid water can still exist under certain conditions.

12. Yearly surface temperature compared to the 20th-century average from 1880–2022. Blue bars indicate cooler-than-average years; red bars show warmer-than-average years. NOAA Climate.gov graph.

13. Water Dissolves & transports chemicals within and to and from a cell Water is regularly available. Life can go dormant between wet periods, but, eventually, water needs to be available.

14. According to Study of WHO: In 2021, over 2 billion people live in water-stressed countries, which is expected to be worse problem in some regions as result of climate change and population growth. In 2022, globally, at least 1.7 billion people use a drinking water source contaminated with feces. Microbial contamination of drinking-water as a result of contamination with feces poses the greatest risk to drinking-water safety.

15. A tmosphere Earth's atmosphere is composed of several gases, primarily nitrogen (about 78%) and oxygen (about 21%). The remaining approximately 1% includes trace gases Traps heat, shields the surface from harmful radiation, and provides chemicals needed for life, such as nitrogen and carbon dioxide. Earth & Venus are the right size to hold a sufficient-sized atmosphere. Earth’s atmosphere is about 100 miles thick. It keeps the surface warm & protects it from radiation & small- to medium-sized meteorites.

16. Strong El Niño expected to drive record-breaking global surface temperatures and trigger climate crises in 2023–2024. This phenomenon will lead to a rapid increase in Global Mean Surface Temperature (GMST), a crucial climate indicator. The study predicts a 17% chance that 2023's GMST will be the highest since 1950, rising to 56% in 2024. These extreme temperatures will likely trigger various climate crises, including marine heat waves, reduced oceanic diversity, sea level rise, and crop yield reductions.

17. Energy Organisms use light or chemical energy to run their life processes. With a steady input of either light or chemical energy, cells can run the chemical reactions necessary for life .

18. More Filipinos facing hunger in 2nd quarter 2023 Study found that 10.4 percent of Filipino families experienced “involuntary hunger” at least once between March to June 2023. The figure was higher than March 2023’s 9.8 percent but lower than December 2022’s 11.8 percent. The agency defines involuntary hunger as “being hungry and not having anything to eat.” The research was conducted from June 28 to July 1, 2023

19. Nutrient Used to build and maintain an organism’s body All solid planets and moon have the same general chemical make up, so nutrients are present. Those with a water cycle or volcanic activity can transports and replenish the chemicals required by living organisms.

20. Child alert: Severe wasting Also known as severe acute malnutrition, severe wasting is an overlooked but devastating child survival emergency. Severe wasting, a deadly form of undernutrition, poses a major threat to child survival, causing 1 in 5 deaths among children under 5. It results from lack of nutritious food and diseases like diarrhea, measles, and malaria, compromising a child's immunity. Despite affecting 13.6 million children globally, severe wasting is often overlooked. Ongoing conflicts, climate emergencies, and the war in Ukraine exacerbate the situation, plunging the world into a food crisis. Child wasting has risen significantly, Immediate action is crucial to prevent child deaths from severe wasting.

21. Why the Earth Habitable? 1. It has the Right Distance from the Sun. Earth is the third planet from the Sun at a distance of about 93 million miles (150 million km).

22. Why the Earth Habitable? 2. It is protected from the harmful solar radiation by its magnetic field.

23. Why the Earth Habitable? 3. It Kept warm by an insulating atmosphere

24. Why the Earth Habitable? 3. It has the right amount of ingredient for life, including water and carbon.

25. Is there a possibility that there are other planets that are habitable aside from Earth.
