Which statement regarding real and virtual images is correct? Rays of light emanate from a virtual image, but only appear to do
SpyIntel [72]

Answer:

Rays of light emanate from a real image, but only appear to do so from a virtual image.

Explanation:

  • The real images are inverted to the object and rays of light are emitted from the virtual object tends to do so and this image is always bigger than the object.
  • Thus a real image occurs where the rays of light converge and a virtual Image occurs when the rays of light diverge and a virtual image can't be projected to a screen as compared to a real image.

The technique called radiometric dating is based on
Dima020 [189]

Answer:

D) the steady, clocklike decay of certain radioactive isotopes over time.

Explanation:

Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.

For example, when rocks are formed, such as igneous rocks (formed when molten rocks cools), certain radioactive atoms are trapped inside the rocks during this formation process. Then these radioactive atoms decay over time.

The age of the rock can be estimated by comparing the occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.

From the options;

A) this is about the formation of the radioactive molecules and not about radiometric dating

B) this is radiocarbon dating (cabon dating/carbon-14 dating)

C) the <em>assumption </em>is wrong since the radioactive isotopes decays not accumulate.

D) the corect option as I explained earlier.

Match the climate zone in column 1 to the characteristic in column 2.
Aliun [14]

The correct matches are:

- A. Tropical - On the Equator;

- B. Dry - Near the Equator;

- C. Moderate - Mildest weather;

- D. Continental - Severe temperature changes;

The climate types differ from one place to another on our planet, and in general they are separated in zones in accordance to the latitude at which they are.

The tropical climate is the one that lies on and around the Equator, and it is warm and wet for the whole year. Little north and south of the Equator we encounter the dry climates, where the landscape is occupied by deserts, with extremely high temperatures, and very little precipitation. Further north come the moderate climate types and the continental climate types, they are similar to each other, but the temperatures in the moderate climates have less variation, while in the continental ones it is much bigger, also the moderate ones have more precipitation, and the continental ones have less precipitation. They are both in the mid-latitudes.

Many climate scientists set the upper limit of carbon dioxide that we should not cross at 560 ppm. In 2011, the atmospheric conc
Vlad [161]

Answer:

5) All of the above are correct.

Explanation:

Carbon dioxide is a greenhouse gas. When its concentration in the atmoshpere rises above normal, it can affect the climate pattern and lead to climate change.

Carbon dioxide prevents outgoing solar radiation from escaping the earth's atmosphere and this warms the earth surface. The more the presence of the gas, the more heating that would result.

Excessive release of carbon dioxide causes a phenomenon known as global warming. Global warming is simply the warming of the globe.

The consequences includes:

  • Melting of Greenland ice sheets as temperature spikes.
  • Glaciers and permafrosts in temperate and polar regions will melt.
  • Ocean acidification due to dissolution of excess carbon dioxide in sea water to form carbonic acid.
  • There is general increase in surface temperature due to accelerated warming.
