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.

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.

There are many uses for permanent magnets and temporary magnets like an electromagnet. Electric appliances with electric motors use magnets to turn electricity into motion. Other examples include electric toothbrushes, fans, lawnmowers, and anything else containing a motor.
Magnets are used to hold doors closed, such as in refrigerators, kitchen cabinets and others. Magnets are also used to read and write data on a computer's hard drive or on old-fashioned cassette tapes. There are more magnets in headphones and stereo speakers which help to turn stored music back into the sounds you can hear.
In summary, magnetism is another property of some kinds of matter. There are two poles to a magnet, the south pole and the north pole. Like poles repel and unlike poles repel. There are two different kinds of magnets, temporary and permanent. A temporary magnet can be made by using electricity. All magnets contain an invisible electromagnetic field which surrounds the magnet. There are many uses for magnets, from holding doors closed to helping music sound better with the magnets inside of speakers.
Based on the information provided above how would you describe a magnet?
Answers
Answer:
A magnet is a piece of metal with a strong attraction to another metal object. The attraction a magnet produces is called a "magnetic field."
This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, and so on. and attracts or repels other magnets.
Most magnets are made of iron, and magnets are used in many common items like cassette tapes, credit cards, toys, and compasses. Magnets are used to make a tight seal on the doors to refrigerators and freezers.

What does latitude have to do with the prevailing westerlies?
Answers
Answer:
Prevailing Westerlies are the winds in the middle latitudes between 35 and 65 degrees latitude. ... This creates frictional or drag in the motion which ultimately slows the Westerlies down. The strongest westerly winds in the middle latitudes can come in the Roaring Forties which is between 40 and 50 degrees latitude.

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.
B) Runoff builds up the coastline, depositing sediment, disrupting habitats of marine wildlife.
Runoff can lead to overgrowth of algae that can cause oxygen deprivation and create a dead zone.
C) Runoff carries pollutants into the ocean, causing illness and death of vulnerable marine populations.
D) Runoff can carry bacteria, viruses, and other pathogens from pet and livestock waste that can harm shellfish and other marine organisms.
Pls give explanation behind if possible

Answers
Answer:
B,C,D
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.

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.
