astronomy

Do you know anything about astronomy?

Astronomy is the study of the universe.

 

solar system

Why do scientists think something could be hidden beyond the edge of our solar system?

In all cases, the images reveal lots of details about the surface of our neighbor in the solar system.

 

religion

Their interest localized on the subject of religion.

Maybe religion should help to straighten him out.

 

atom

The power of the atom can be used to produce electricity.

Each one about the size of an atom.

 

billion

The new estimates now tell us that more than one billion people experience some form of disability.

We must never forget: these diseases affect the “bottom billion”, the poorest of the poor living in the hardest to reach places.

 

globe

We directed radio waves around the globe.

The energy will encircle the globe and effect each of you.

 

carbon

Across the world, forests and the soil beneath them absorb about a quarter of all carbon emissions.

That would be odd, though, since it would be a waste of valuable carbon.

 

atmosphere

The talks proceeded in a friendly atmosphere.

Industrial wastes are poisoning the atmosphere of the country.

 

fundamental

We should direct our attention at the fundamental question.

Independence and sovereign equality among states is a fundamental principle of international law.

 

acid

Acid bites into metals.

Battery acid had eroded the engine.

 

chain

I have detached the watch from the chain.

The chain has fallen foul of some plants in the water.

 

multiply

This will multiply our chances of success.

Each module was an arithmetical command such as add, subtract, multiply, cosine, sine.

 

oxygen

Carbon dioxide consists of carbon and oxygen.

Water can be reduced to oxygen and hydrogen by electrolysis.

 

thus

Thus the first worker's league came into being.

She misinterpreted the implications of his letter and thus misunderstood his intentions.

 

dioxide

They say concentrations of smoke and major air pollutants such as sulphur dioxide have now decreased

Mosquitoes follow carbon dioxide gas because it is breathed out by animals, transmitting diseases such as malaria and dengue in the process.

 

carbon dioxide

By 2030 China might be sequestering 2 percent of the carbon dioxide its power plants produce.

Studying the light in each image could also reveal physical characteristics, such as the presence of water or carbon dioxide.

 

puzzle

The puzzle defied solution.

This one was quite the puzzle for me.

 

biology

In biology class we had to dissect a frog.

I couldn’t touch the first question in the biology paper.

 

biologist

Every time a biologist discovers a new species, there is the opportunity to honour someone or something.

One biologist developed a formula for how much genetic material would have to be to saved in the act of altruism for it to be worthwhile.

 

gravity

The stone rolled down the mountain by gravity.

We here on Earth obey the same laws of light and gravity as someone in a far off corner of the universe.

 

satellite

The satellite will be thrown into space.

We can communicate with the outside world by email and satellite phone.

 

gentle

She is of such a gentle nature.

Nothing can ruffle her gentle disposition.

 

physicist

Madame Curie was the physicist with expertise in chemistry

A German physicist showed that the electrons’ energy depended instead on the color (or the frequency) of the light.

 

block out

In theory, planetary dust could block out UV rays.

Biofilm, the researchers think, could serve a dual function. It could help bacterial colonies grow toward resources as a collective swarm, and it might also help block out competing colonies.

 

climate

These two regions differ greatly in climate.

You'll soon get acclimatized to the climate of the country.

 

crash

He narrowly escaped in the air crash.

What was it like to write about the crash after all these years?

 

spaceship

They successfully lofted a spaceship into orbit.

I’d use a toy spaceship or plastic dinosaur and try copying the shot

 

float

There is not enough water to float the ship.

Some days, depending on the weather, they appear to just float, soar and really enjoy themselves.
