Tropical Rainforest Climate

Question 1

Which of the following best describes the climate in a tropical rainforest?

Accepted Answer

It is warm all year, about 27 °C, and gets more than 2000 mm of rain each year.

Answer

It is hot in summer and dry in winter, with about 500 mm of rain each year.

Answer

It is cool most of the year, around 15 °C, and only rains a little in winter.

Answer

It is cold and snowy, with less than 100 mm of rain each year.

Question 2

Two forests get the same amount of rain each year – 2500 mm. Forest A is warm all the time, about 27 °C, while Forest B is cooler, about 16 °C. Which reason best explains why many more plants grow quickly and become tall in Forest A than in Forest B?

Accepted Answer

Warm temperatures speed up plant metabolism and the plenty of water lets the plants use that energy to grow fast.

Answer

The hot forest dries out the soil, so there is not enough water for plants to grow.

Answer

The cooler forest gets more sunlight, which makes plants grow slower.

Answer

In the cooler forest the rain often freezes, so the water cannot be used by plants.

Question 3

Two forests have the same kind of soil. Forest Green gets about 2,300 mm of rain each year and stays around 28 °C all year. Forest Cool gets about 1,200 mm of rain each year and stays around 22 °C. Which explanation best shows why plants in Forest Green can grow faster and there are many more kinds of plants than in Forest Cool?

Accepted Answer

The warm temperature speeds up plant metabolism and the abundant rain supplies water all year, so together they give ideal conditions for fast growth and many species.

Answer

The soil in Forest Green contains more nutrients than the soil in Forest Cool.

Answer

Even though Forest Cool is cooler, its lower rainfall means plants have to work harder, which makes them stronger.

Answer

Forest Green receives more sunlight than Forest Cool, which lets its plants grow better.
