How do human activities change the planet?

Final Answer: Human activities can change the planet in many ways. They can create was to hurt the environment. But we can also do a lot of things to help the environment like composting and recycling. Also we can hurt the soil with pollution which could affect everyone because there wouldn't be place to grow food.

What issues does waste from humans cause?

Claim: Waste from humans can damage the environment and the land. It can also hurt and kill wildlife.

A connection for me is, I cause waste by doing a lot of things. I also recycle things

We can reduce the amount of waste we make by buying dish towels instead of paper towels, buying rechargeable batteries, and use canvas bags instead of plastic ones.

Synthetic material are things that are formed chemically and cant be formed in nature like polyester, plastic, and parts of electronics.

Biodegradable is able to be broken down

Recyclable is being able to reuse the materials

Compostable is something that's rich in nutrients and will help plants grow.

What is the impact of developing and using energy resources on Earth’s living and non-living systems?

Claim: It's good that we’ve developed ways of using energy to because it can provide us with electricity. But it's bad because some ways we’ve use the energy but bad emissions into the environment

We have many wind turbines around us so we can produce electricity.

There are 3 types of mining which are open pit mining, strip mining, and quarrying.

Solution mining creates big caves underground which in time might collapse and cause damage to things above the ground.

Most of these fossil fuels are obtained by mining

Coal, oil, and natural gas are formed from the remains of organisms.

The energy is taken from fossil fuels and then it is converted into electricity.

Why is carbon important?

Claim: Carbon is important because it is basically the backbone of life.

We breath CO2 and are a source of it.

A Carbon Flux is the rate of flow of a carbon.

A carbon reservoir a supply or source of something.

Sources of Carbon are: Human sources, Fossil fuels, Land use changes, and industrial process.

Some carbon sinks are: Plants, soil, and oceans.

How does water affect Earth’s surface processes?

Claim: Water can affect surface processes in many way. Water can flood certain places and wash certain places away. It can also carve out areas and canyons. Water can also make new landforms overtime.

We live in a place with good soil so we can grow plants and crops really good.

Soil texture is important because it changes the amount water can hold and how much infiltration it has.

Water evaporates from the ground, rises into the atmosphere, condenses into rain or snow in clouds, and falls again to the ground as precipitation.

The steps of erosion are Detachment of soil, movement, deposition.

Soil is also really important because its mostly how we grow food and if the soil isn't good then plant will have a hard time growing.

How did life and Earth systems coevolve?

Claim: Life and Earth systems coevolved because the earth is the perfect distance from the sun. This is called the goldilocks condition. The land is also perfect for life to thrive and that's how we have coevolved

In my house there's a goldilocks temp where it's perfect for me just like there a perfect temp range for the earth.

Our earth is the perfect land temp so life can thrive here

Since the earth is so perfect for us to live here we have evolved to make it even better for us to live here depending on the location that you are at.

Goldilocks Condition - The Earth is the perfect distance away from the sun for living things to thrive and the perfect distance from the sun so it can have a lot of surface water.

If the earth was a little bit hotter than life may not be able to live here.

How do some changes create feedback that affect other Earth systems?

Claim: Things happening in one of the Earth's systems can positively or negatively affect other systems. For example Rain and water in the hydrosphere can form and erode rock in the geosphere.

Wind form the atmosphere will blow my golf ball and make me hate golf

Negative feedback is a stabilizing change

Positive feedback is be an amplifying change.

The Atmosphere is oxygen, nitrogen, and water vapor

The Biosphere is Plants, humans, and insects

The Geosphere is the land, Rocks, core, and mantle

The Hydrosphere is oceans, rivers, and ice caps

More examples of the systems interacting are: Atmosphere-Hydrosphere: Water evaporating from the hydrosphere to the atmosphere. Hydrosphere-Biosphere: Rain from the hydrosphere will water plants from the biosphere
