Back

Precipitation is crucial for determining the types of vegetation and animal life in a biome. It influences the ecosystem's health and biodiversity.

Front

What is the tropical rainforest biome known for?

Back

The tropical rainforest biome is known for its high biodiversity, warm temperatures, and high levels of precipitation, often exceeding 2000 mm annually.

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

Front

What is an observation in the scientific method?

Back

An observation is the act of noting and recording something with instruments or through the senses, often leading to questions or hypotheses.

Front

What is a hypothesis?

Back
