How do the growth rings of a tree provide evidence of climate conditions of previous years?
A2. Using fossil tree rings, a complete year by year record is available for about 11 000 years, and with an accuracy of as little as 1 year! Dendrochronology is the name of this science.
A1. Thicker rings indicate that the climate during that time period was favorable to growth, which may indicate that there were optimal rainfall and temperatures during that time, whereas thinner rings indicate the opposite.

What provides evidence of a warm humid climate at the beginning of the Cenozoic Era?
Fossil evidence of tropical plants and animals found in regions that are currently temperate zones, as well as sediment deposits indicating warm, moist conditions, provide evidence of a warm and humid climate during the beginning of the Cenozoic Era.
Evidence of climate changes and conditions that affected early societies are gathered from?
Evidence of climate changes and conditions that affected early societies can be gathered from sources such as ice core samples, tree rings, pollen records, sediment layers, and historical documents. These sources provide valuable information about temperature fluctuations, rainfall patterns, and the impact of natural disasters on past civilizations.
What are climate clues?
Climate clues are evidence or indicators that help scientists understand historical changes in the Earth's climate. These clues can include ice cores, tree rings, sediment layers, and temperature records which provide information about past climate conditions and trends. By studying these clues, scientists can reconstruct past climates and predict future climate patterns.
What two pieces of evidence led to the discovery of how an ice age can happen?
Two key pieces of evidence that led to the discovery of how an ice age can happen are the study of ice cores, which provide a record of past climate conditions, and the identification of Milankovitch cycles, which are variations in Earth's orbit and axial tilt that can influence climate over long periods of time. These pieces of evidence helped scientists better understand the mechanisms that can trigger ice ages.
What evidence do we have that earth went through an ice age?
Evidence for past ice ages includes geological features such as glacial moraines, striations, and erratic boulders. Additionally, ice cores and sediment cores can provide information about past climate conditions, including periods of glaciation. Climate models and the distribution of certain fossils also support the theory of past ice ages on Earth.

How do glaciers provide evidence of climate change?
Glacial shrinkage from year to year indicates our climate is not sufficiently cool to preserve glacial ice. This suggests the climate is warming, overall.
What evidence do fossils provide of the environments past and present?
changes in the environment e.g. the place, temperature, climate.
Can you provide a citation for the statement that "climate change is a pressing issue that requires immediate action"?
Yes, the Intergovernmental Panel on Climate Change (IPCC) reports and scientific studies provide evidence that climate change is a pressing issue that requires immediate action.

Why Describe how fossils can provide evidence of how environmental conditions and life have changed during earths history?
hi
How did fossil provide evidence for Continental drift?
It is any trace of an ancient organism that has been preserved in rock.Fossils provided evidence for continental drift by Wegener's hypothesis. Wegener studied land features, fossils, and evidence of climate change.
How does the combination of Georgia's climate and soil conditions contribute to agricultural production?
Georgia's climate and soil conditions are ideal for a variety of crops such as peaches, pecans, and peanuts. The warm climate allows for a long growing season, while the fertile soils provide necessary nutrients for plant growth. These conditions make Georgia a productive agricultural region for a range of crops.
What health benefits can accupunture provide?
There is some evidence that acupuncture can reduce the chance of nausea and vomiting after a surgical procedure. The evidence for it affecting other health conditions is controversial, but trials continue.
