Where do earthquakes occur?

Answers

Answer:

Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the 'Ring of Fire'; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.

From left to right, follow the dots in line 1 with your finger. Count a steady beat out loud, and time your motion so your finger crosses a dot at the end of each beat. Don’t pause at the dots, and move as smoothly as you can. A good way to count is to say or think “1 Mississippi, 2 Mississippi,” and so on. Is your finger moving at a constant rate, or is the rate changing?

Answers

Answer:

A) The rate changes as i move my finger

It changes as i move my finger.

explain why severe storms occur along front

Answers

Answer:

Violently rising air ahead of cold fronts often leads to powerful thunderstorms.

Explanation:

Answer:

Stormy weather as the warm air mass at the surface rises above the cool air mass,

Explanation:

vigorous rising motion is often produced, leading to the development of showers and occasionally severe thunderstorms.

Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. ... These clouds form in the warm air that is high above the cool air. As the front passes over an area, the clouds become lower, and rain is likely.

What is the equation for the mechanical advantage of a lever?

MA = length of effort arm / length of resistance arm

MA = length of resistance arm/length of the effort arm

MA = length of effort arm + length of resistance arm

MA = length of effort arm * length of resistance arm

I think it is the second one, is that correct? HELP!

Answers

Answer:

MA = length of resistance arm/length of the effort arm

MA = length of resistance arm/length of the effort arm

PLS HELP!!! Which are examples of a phase change? (Select all that apply.)
evaporating water
cutting wood
frying eggs
melting butter

Answers

Answer:

evaporating water, frying eggs, melting butter.

Explanation:

Answer:

Evaporating water

Melting butter.

Explanation:

For a phase change to occur, heat energy needs to be released or absorb, and the process can be reversible. A phase change can cause physical changes but no new substance is formed.

These are examples of phases changes:

Melting: solid to a liquid (Melting butter)Freezing: liquid to a solidVaporization/Evaporation: liquid to a gas (Evaporating water)Condensation: gas to a liquidSublimation: solid to a gasDeposition: gas to a solid

→Frying eggs in a chemical change (not reversible, a new substance is formed).

→Cutting wood is a physical change.

(*) My little brother (5th grade) just took the test and -evaporating water & melting butter- were the right answers.
