1. In which direction are the annual rings of big trees denser?

2. What can annual rings tell us?

Generally speaking, the rings of large trees are denser toward the shady side, that is, the north. Because one annual ring is the growth amount of a big tree in one year, and whether a big tree grows vigorously or not depends on the light conditions. For large trees, the lighting conditions facing the south are definitely better than those facing the north, so the growth of large trees facing the south is more vigorous than those facing the north, and the annual rings facing the south are wider than those facing the north.

1. To which side do the annual rings of large trees have denser growth rings?

1. Look at the direction: The annual rings of big trees may be wide or narrow. The side with wide and sparse annual rings indicates that the tree is growing well and faces the sun, that is, the south. The side with narrow and dense growth rings indicates that the tree is growing poorly and is facing the shady side, that is, the north.

2. Look at the age: One annual ring is the growth of a big tree in one year. We can judge how many years the tree has lived by looking at the number of annual rings. But if the temperature drops sharply in a certain year and then rises again, then there are likely to be two growth rings in that year.

3. Look at the climate: the annual rings of big trees Some are wide and some are narrow. If a big tree has many narrow growth rings, and suddenly a very wide growth ring appears. This shows that the local environmental and climate conditions were poor at first, and the trees grew slowly. Later, when the climate became suitable, the trees grew rapidly, and a very wide annual ring appeared.
