Light energy or sunlight
What is the gas that is the result of nuclear fusion?
Helium
What kind of fossil fuel comes from decomposed plant parts?
Coal
What is energy that comes from the sun called?
Solar energy
Why does the sun look bigger and brighter than other stars?
Because the sun is the nearest star to Earth
What is the process called that converts the sun's energy to a form of energy that gets passed along to every organism in every food web on Earth?
Photosynthesis
What do scientists call a natural resource of which a finite amount exists, or one which cannot be replaced with current available technologies
Non-renewable resource
What do scientists call all of the water on, under, and above the earth?
The Hydrosphere
What is the definition of atmosphere?
The layer of gases that surround a planet
What makes up 92% of our sun?
Hydrogen
Why does the sun have a stronger force of gravity than Earth?
The sun has much more mass
What is the definition of Hydrogen?
The chemical element, consisting of one proton, and one electron
What is the Biosphere?
All the living parts of the Earth
Wat is the equivalent of the energy that is released by the sun every second of every day?
1 trillion megaton bomb
Name 3 types of renewable resources that the sun is responsible for
3 types of renewable resources that the sun is responsible for are solar, hydroelectric and wind energy
They are responsible for temperature, climate, weather patterns, they even have a great influence on the types of marine animals that live in the waters
What is the definition of fusion?
A nuclear reaction in which new nuclei combine to produce more massive nuclei resulting in the release of large amounts of energy
What is the definition of fossil fuels that i gave you?
Nonrenewable resources such as coal, petroleum, or natural gas that supplies the world with 85% of it's energy.
How do they calculate the amount of energy that results from nuclear fusion?
They take the missing mass (in kilograms) of the resulting new helium atom from the two combined hydrogen atoms and multiple it by 90 quadrillion.
How was solar energy converted into fossil fuels?
Plant cells convert solar energy to chemical energy in glucose during the process of photosynthesis. Plants transfer the energy from glucose to a variety of energy rich hydrocarbon compounds as they assemble body tissues. Over millions of years, geological processes convert decaying plant matter into fossil fuels, which retain the chemical energy from plants in hydrocarbon compounds. It is this chemical energy that transforms to heat energy when fossil fuels are burned.
How is the sun responsible for most renewable energy resources?
Sunlight drives the water cycle by moving water from the surface into the atmosphere during evaporation. Eventually, this water vapor condenses and falls as precipitation. When the water falls on land, it flows downward and ends up in rivers and streams. Without the water cycle, there would be no flowing water to power hydroelectric systems. Energy from the sun also helps to cycle air. Sunlight heats up some portions of the earth, more than others. As a result, some air masses are warmer and less dense than others. This difference causes air masses to move since he always travels to cooler regions and higher density areas travel to lower density areas. This is causing wind.
Define the water cycle and describe each step as well as explaining the force/energy that drives each.
The water cycle is the continual movement of water between the land, ocean, and the air and it starts with evaporation where the heat energy of the sun changes liquid water to it's gaseous state at the surface. The water vapor rises in the air where cooler temperatures prevail. This lack of energy initiates the process of condensation where the gaseous water changes back to liquid. The more that condensates, the larger the liquid droplets become and then gravity takes over and brings the water droplets down to the surface of the Earth in the process of precipitation. Gravity drives the water downward through Runoff where some infiltrates back into the Earth and much is channeled back into Storage such as the Ocean
