How is the length of a day?

What is the length of day light?

How do some rainforest plants get sunlight?

Many plants have waxy leaves that help repel the rain. Rainforest plants must either adapt to living with little sunlight under the forest canopy or grow quickly and find ways of reaching the sunlight above the canopy. For example vines quickly grow up the trunks and branches of trees to reach sunlight.

Why is a day 23 hours and 56 minutes?

The sidereal day happens each time Earth completes a 360-degree rotation. That takes 23 hours and 56 minutes. The solar day — the one humans count in the calendar — happens when Earth spins just a little further, and the sun is at the same point in the sky as it was 24 hours ago.

Can you see the sun in the rainforest?

Although tropical rainforests receive 12 hours of sunlight daily, less than 2% of that sunlight ever reaches the ground. However, the canopy created by the tall trees (100-120 feet) and the understory, prevents sunlight from reaching the ground.

Why does only a small amount of light reach the understory and forest floor?

Because of the very dense canopy, little sunlight reaches the ground. In a dense forest, the canopy trees can block out over 95% of the sunlight. Though Tarzan movies would have us think otherwise, there is actually relatively little vegetation on the rainforest floor.

How many seasons does the tropical rainforest have?

The cooler, drier months, from May to September, are the best time to visit. The weather is pleasantly warm during this time, with reduced humidity and the maximum temperature averaging 26 degrees Celsius.
