Temperature and Trees Flashcard

Front

What is the role of a dense canopy in a forest ecosystem?

Back

A dense canopy helps to keep ground temperatures lower by blocking direct sunlight, which promotes the growth of shade-tolerant species.

Front

Define 'canopy' in the context of a forest.

Back

The canopy is the uppermost layer of leaves and branches in a forest, formed by the tops of trees.

Front

What is the primary factor influencing soil surface temperature during the day?

Back

Solar radiation is the primary factor influencing soil surface temperature, as it directly heats the soil.

Front

Explain why soil surface temperatures are typically lower in a dense forest compared to an open field.

Back

Soil surface temperatures are lower in a dense forest because the forest canopy reduces direct sunlight reaching the soil.

Front

Which tree species is adapted to regions with consistently low temperatures?

Back

Spruce trees are adapted to regions with consistently low temperatures.

Front

What is the effect of increased canopy gaps on ground temperature?

Back

Increasing canopy gaps can raise ground temperature by allowing more sunlight to reach the forest floor.

Front

How does soil compaction affect tree growth?

Back

Soil compaction can restrict root growth and reduce water and nutrient availability, negatively impacting tree growth.

Front

What is the understory in a forest?

Back

The understory is the layer of vegetation beneath the canopy, consisting of smaller trees, shrubs, and young plants.

Front

How does wind speed influence temperature in a forest?

Back

Wind speed can affect temperature by increasing evaporation rates and cooling the air, but its impact is generally less significant than solar radiation.

Front

What adaptations do trees in colder climates have?

Back

Trees in colder climates, like spruce, often have needle-like leaves to reduce water loss and are conical in shape to shed snow.
