Answer:
The Sun
Explanation:
It is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

how is sunlight related to seasons and the tilt of the earths axsis
Answers
Answer:
The seasons are caused by the tilted axis of the Earth. Over the course of the year, various portions of the planet are exposed to the Sun's most direct rays. As a result, as the North Pole tilts toward the Sun, the Northern Hemisphere experiences summer. In addition, when the South Pole tilts toward the Sun, it is winter in the Northern Hemisphere, and vice versa.

Describe tectonic plates and explain how they “float” on the Earth’s surface (what do they float on and what causes their movement). (site 1)
Answers
Answer:
There is constant heat and radiation given off from the center of the Earth. That energy is what constantly heats the rocks and melts them. The tectonic plates are floating on top of the molten rock and moving around the planet.
Explanation:
The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.
Another method in creating a temporary magnet is by using electricity. This can be done by wrapping an iron nail with a coil of wire. By passing electricity through the coil of wire the iron nail will become a temporary magnet or an electromagnet. The strength of the electromagnet depends on the size of the electric current and the number of times the coil is wrapped around the nail. If the electricity stops flowing through the coil the nail will no longer be magnetic.

If Earth's axis were not tilted, could any area have both a hot summer and a cold winter?
Answers
Answer: What if though the Earth was not tilted? In this case the plane of the Earth's poles would always be perpendicular to the sun. The sun would always be just on the horizon 24 hours a day on every day at the poles. ... It would still be warm at the equator and cold at the poles.
Explanation: Hopefully this Helped
If the earth axis was not tilted the sun would only shine in one place. (the middle) Leaving the rest of the world dark and cold. And no with out the tilt seasons would simply disappear. With out the tilt we would surely be frozen or just really hot.

What is electrostatics?Electrostatics is the study of stationary electric charges. Electric charge is the charge associated with matter that causes it to create and experience a magnetic and electric effect.
When a plastic rod is touched with fur or a glass rod is rubbed with silk, pieces of paper are attracted, indicating that both rods are electrically charged.
Two particles with opposite charges repel each other, whereas two particles with opposite charges attract each other (see Coulomb's law). The electric force between two charged particles is substantially stronger than the gravitational force.
Therefore, the positively charged objects do not attract or repel an uncharged object. The correct option is C.

But can someone explain the path electrons goes when you serie/parallel connect the batteries. I understand it with lamps but not batteries. Try to explain it as simple as possible because I'm a bit too young for this but I'm curious
Answers
Answer:
It comes out the positive side of the battery and goes in to the negative side of the battery
Explanation:
There are already electrons in wires in a circuit before you add the battery. By adding the battery, you're giving the electrons the energy it needs to move along the circuit.
In a series circuit, the circuit is one continuous loop so there is only one path for the electrons to go - out of the positive side of the battery and around the circuit then goes back into the negative side of the battery.
However, with a parallel circuit, there are two or more ways the electrons can go so they take the path of least resistance. The electrons still go out the positive side of a battery but along the circuit, the electrons will go through the path of least resistance ( I tend to think of it like a net with holes in it - the lower the resistance the bigger the holes for the electrons to go through so more can fit in a set amount of time ) but the electrons still go out of the positive side and in through the negative

Here,
Molecules are not tiny particles that are parts of atoms. Rather, they are formed when two or more atoms combine chemically.
Neutrons, protons, and electrons, on the other hand, are the three types of particles that make up atoms. Protons and neutrons are found in the nucleus of the atom, while electrons orbit around the nucleus.

When rain falls to the earth, it just doesn't sit there. Instead, the rain water starts moving. Some of the precipitation seeps into the ground to replenishing groundwater. However, most of it flows downhill as runoff. Runoff is important in filling rivers and lakes, but it also changes the landscape by erosion and can be a powerful mover. Flowing water is a powerful force, capable of moving boulders and carving out canyons. Runoff has an impact on streams and rivers, but it also has an impact on the ocean system. What can you infer about the impact of runoff on Ocean life? Choose ALL that apply.
A) Runoff drops a lot of sediment in the ocean, decreasing salinity.

Take a look at a bicycle with gears. Using what you have just learned, answer the following questions:
a. Which gear combination would you like to use when you want to pedal with as few strokes as possible and have your wheels turn as many times as possible?
b. Now you are going up a hill and want to maximize the force you deliver to the wheel. You aren’t concerned with how many strokes you are making, but you want to get as much force to the wheel as possible. Which gear combination would you use now, and why?
Answers
Answer:
answer a: a large front gear with a small back gear
answer b: a small front gear with a large back gear
Explanation:
just simple gearing ratios
To rotate wheels turn many times with few strokes a large front gear with a small back gear is required and to minimize the force a small gear in the front and the large back gear are required. So, when a large amount of energy is applied the bicycle moves more as compared to less energy applied.
What is a Gear?Toothed wheel mounted to a spinning shaft, used as a machine part. With the teeth from one gear engaging the teeth of the other gear, gears work together to transfer and modify rotational movement and tension (turning force) without slipping. The ratios of rotational speeds and shaft torques are constant when a pair of matching gears have teeth that are aligned in circles, or when the gears are serrated wheels. Speed control and torque ratios result from the arrangement of the teeth on non-circular bodies.
Typically, gears are round. Gear teeth's contact surfaces need to be precisely formed to a particular profile in order to transfer movement easily and with a steady speed proportion at every moment.

Caleb is investigating the effect of friction on the motion of an object. He uses the following supplies for the investigation:
a wooden block
three ramps, each ramp is the same height and length but has a different surface (smooth wood, carpet, rough sandpaper)
a stopwatch
Caleb tests his hypothesis that the smooth wood ramp surface causes less friction than the carpet and that the carpet causes less friction than the rough sandpaper.
(THERE IS A PART "A,B,C")
Answers
Place the ramps on the floor and time each ramp for time it takes for wooden block too reach thee floor. The times will be different and thus you can conclude that friction will increase the time
Part b
Caleb uses the same block as this is his control variable that he wants to keep same so that the results are correct and accurate
Part c
The independent variable is the thing you change before you test so it will be the surface on which the wooden block is sliding
The dependent variable is the variable you measure so that will be the time it takes for the block to slide to the bottom.

Answer:

Explanation:
As a runoff flows over the land surface, stormwater picks up potential pollutants that may include sediment, nutrients (from lawn fertilizers), bacteria (from animal and human waste), pesticides (from lawn and garden chemicals), metals (from rooftops and roadways), and petroleum by-products (from leaking vehicles). Pollution originating over a large land area without a single point of origin and generally carried by stormwater is considered non-point pollution. In contrast, point sources of pollution originate from a single point, such as a municipal or industrial discharge pipe. Polluted stormwater runoff can be harmful to plants, animals, and people.
