TRUE OR FALSE:The amount and type of precipitation in temperate rainforests is the same as tropical rainforests.

Answers

Answer:

The given statement is false.

Tropical rainforests are located near the equator and receive precipitation generally in the form of rain. These forests receive a large amount of precipitation throughout the year which can range from 80 inches to 400 inches in a year.  

Temperate rainforests are located on higher altitudes as compared to the tropical rainforests. They receive precipitation in the form of rain and snow. They receive less amount of rain as compared to tropical rainforests. They receive precipitation which lies between 40 inches and 60 inches in a year.

Thus the amount and type of precipitation in tropical and temperate rainforests are different.


definitely false. a tropical rainforest would have much more precipitation.

In which habitat is one likely to find plants that have developed extremely large, broadleaf, evergreen leaves for gathering light, epiphytes, and climbing vines that strangle other plants?

Answers

The answer is a tropical rainforest.
The tropical rainforest is an ecosystem where temperatures are high, and there is enough rain, so plants grow rapidly. This ecosystem is characterized by very large trees, and herbaceous plants must adapt in order to survive in these forests. Because of the high trees, the light is reduced in the lower floors. Therefore, some plants developed large, broadleaf, evergreen leaves to gather as much light as possible in the shady floors of the forest. Epiphytes use those high trees for physical support. Their roots are partly attached to a tree, and partly are free in the atmosphere. This way they can live in higher floors where there is enough light. Similarly, climbing vines crawl on the other trees until they reach the light area.

Which is NOT a property of magnetic field lines?a.
They form complete loops from pole to pole.
b.
They can be directly observed.
c.
They never cross.
d.
They spread out as they get farther from the magnet.

Answers

Answer:The correct answer is option (b).

Explanation:

Properties of magnetic lines:

  • They from closed loop from pole to pole.
  • They never intersect each other.
  • They are stronger near the poles as compare to lines in the middle.
  • They move from north to south pole in air and from south to north in the interior of the magnet.
  • Their density decreases as they move away from the poles.
  • They are not visualized by eyes.

Option (b) is correct as magnetic field lines cannot be directly observed.
The correct answer is (b) They can be directly observed.
