THE RIGHT ONE QWIAEJKNF
Answer: no friction, metal
Explanation: yes
Friction causes an object to slow down after no longer being pushed.
What do you mean by friction?Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
Friction depends on the roughness or the smoothness of the surface which is in contact with the object. If the surface of either object is smooth, then the force of friction will be less.
Walking – When we walk on the ground or the floor, it is the frictional force that is responsible for holding our feet to the ground. On slippery surfaces or ice, the friction present is less, which is why we tend to slip on these surfaces.

What is the fossil connection between Indohyus and the whale? What is the function of this bone? Why do you think these mammals transitioned from land to water?
Answer:
1. Indohyus is an extinct genus of digitigrade artiodactyls known from Eocene fossils in Asia. This small chevrotain-like animal found in the Himalayas is one of the earliest known non-cetacean ancestors of whales.
2. While whale bones are real bones, they are apparantly a little "spongier" and less stiff than most land animal bones. Afterall, the bones don't have to hold the animal up. They just have to help it keep its shape while floating in what is pretty much a zero-G world.
3. I think they transitioned to water because they have to escaped predators so they move into the sea to survive

What are three ways to determine the age of earth specimens and help prove that the changes on the earth occur over very long periods of time?
Answer:
The decay of potassium to argon, uranium to lead, and one isotope of lead to another are some common yardsticks used to date very old rocks. These dating methods allow scientists to put real ages on rocks with astonishing accuracy.
Explanation:
The best estimate for Earth's age is based on radiometric dating of fragments from the Canyon Diablo iron meteorite. From the fragments, scientists calculated the relative abundances of elements that formed as radioactive uranium decayed over billions of years.

BRAINLIST What causes air to move towards the water from the land during the night?
-
The dry air over the land is heavier than the air over the water that contains more water vapor.
The ground retains the heat from the Sun longer than the water.
The ground cools faster at night than the water which retains its heat warming the air above at.
Gravity moves the air towards the water because water is lower than the land.
Answer:At night, the roles reverse. The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. ... This causes the low surface pressure to shift to over the ocean during the night and the high surface pressure to move over the land.
Explanation:The ground cools faster at night than the water wich retains its heat warming the air above at

How would you change this setup so that the Shallow sensor does not break but still sends important information? (Remember: We still want it to detection to happen)
Answer:
Many coastal areas of the United States are at risk for tsunamis. After the catastrophic 2004 tsunami in the Indian Ocean, legislation was passed to expand U.S. tsunami warning capabilities. Since then, the nation has made progress in several related areas on both the federal and state levels. At the federal level, NOAA has improved the ability to detect and forecast tsunamis by expanding the sensor network. Other federal and state activities to increase tsunami safety include: improvements to tsunami hazard and evacuation maps for many coastal communities; vulnerability assessments of some coastal populations in several states; and new efforts to increase public awareness of the hazard and how to respond.
Tsunami Warning and Preparedness explores the advances made in tsunami detection and preparedness, and identifies the challenges that still remain. The book describes areas of research and development that would improve tsunami education, preparation, and detection, especially with tsunamis that arrive less than an hour after the triggering event. It asserts that seamless coordination between the two Tsunami Warning Centers and clear communications to local officials and the public could create a timely and effective response to coastal communities facing a pending tsuanami.
According to Tsunami Warning and Preparedness, minimizing future losses to the nation from tsunamis requires persistent progress across the broad spectrum of efforts including: risk assessment, public education, government coordination, detection and forecasting, and warning-center operations. The book also suggests designing effective interagency exercises, using professional emergency-management standards to prepare communities, and prioritizing funding based on tsunami risk.

A. The environment is adding carbon faster than humans are adding carbon.
B. The environment is adding carbon slower than humans are adding carbon.
C. Humans are adding carbon faster than the environment can take up and store carbon.
D. Humans are adding carbon slower than the environment can take up and store carbon. Talent
Answer:
C, Humans are adding carbon faster than the environment can take up and store carbon.
Explanation:
The other answer choices don’t make sense. Humans are impacting the carbon footprint at a much quicker rate & far more heavily so than other organisms. Hope this is correct & helps you out:)
The statement that best describes the concern scientists have about the carbon cycle is : ( C ) Humans are adding carbon faster than the environment can take up and store carbon.
The increase in the rate of industrialization globally has caused a tremendous increase in the rate of fossil fuels been burnt and the increase of gas flaring activities during oil exploration.
The increased burning of fossil fuels adds Carbon more rapidly into the atmosphere than the amount of carbon leaving the atmosphere into carbon deposits.
Hence we can conclude that The statement that best describes the concern scientists have about the carbon cycle is : ( C ) Humans are adding carbon faster than the environment can take up and store carbon.

describe what life might have been like millions of years ago. what evidence is there for this?
Answer:
The oldest dated zircons date from about 4,400 million years ago. Earth was initially molten due to extreme volcanism and frequent collisions with other bodies. Eventually, the outer layer of the planet cooled to form a solid crust when water began accumulating in the atmosphere.
In millions of year planet's surface resemble lava and after that earth, cools and earliest zircons are dated around 4,400 million years ago
What was life has been millions of years ago?Our planet's surface resembled a ball of molten lava and fire millions of years ago. Different terrains were being created as a result of the space rocks and other debris colliding with the earth.
The planet was likely made almost completely of molten lava at first since it was so hot. The earth cooled over a few hundred million years and seas of liquid water developed.
The earliest zircons that have been dated are from around 4,400 million years ago. Due to intense volcanism and frequent collisions with other bodies, the earth was first molten.
Therefore planet's lava surface becomes cool millions of years ago to form life.
