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.

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.

How is the levitation of the SCMagLev train achieved? Just write a sentence.
Answer:
The SCMaglev (superconducting maglev, formerly called the MLU) is a magnetic levitation (maglev) railway system developed by Central Japan Railway Company (JR Central) and the Railway Technical Research InstituteAnswer:
In the case of passive levitation, the levitating-effect is achieved by speed.

Answer:
sorry, but the Question at hand is to hard for my delicate mind
Explanation:
Sarah and Charlie both investigated the properties of rocks they found while on a walk. Take a look at the table with their observations. What was the difference between the two sets of observations?
Sarah's Observations Charlie's Observations
The mineral was metallic. The mineral was non-metallic.
The mineral had cleavage. The mineral did not have cleavage.
The mineral was red. The mineral was red.
The mineral had luster. The mineral had luster.
a Sarah observed that the mineral was metallic and red.
b Charlie observed that the mineral was red and had luster.
c Sarah observed the mineral had cleavage and was metallic.
d Charlie observed the mineral was non-metallic and had luster.
Answer:
b
Explanation:
Answer: C. Sarah observed the mineral had cleavage and was metallic.
Explanation: The answer is C because the question is asking about the difference in their observations. Sarah claimed the mineral had cleavage and was metallic, while Charlie said the opposite.
In which layer of the atmosphere is the ozone layer located?
Answer: im pretty sure its the stratosphere.
Explanation:
need help with this please
Answer:
It cannot be moving without any force pushing behind it as it is only slightly vibrating unless it is a liquid or a gas which in that case is consantly moving around.
Explanation:
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?
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.

HELP!!! GIVING BRAINLIEST AND MANY POINTS!!!
Answer:
first and second photo
speed = distance/time
s = d/t
Segment:
A — 90/30 = 3 m/s
B — 120/60 = 2 m/s
C — 250/50 = 5 m/s
D — 120/40 = 3 m/s
E — 60/20 = 3 m/s
total distance = 90+120+250+120+60 = 640m (meters)
total time = 30+50+60+40+20 = 200 (seconds)
average speed = 640/200 = 3.2 m/s

Answer:
Yes.
Explanation:
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.
