Earth's elliptical orbit

In what type of climate do trees produce narrower rings? cool and dry warm and wet cool and wet warm and dry

cool and dry

Pollen grains help scientists identify plants and make assumptions on past climate conditions. understand tree growth and make assumptions on past climate conditions. understand how Earth was shaped and make assumptions on past climate conditions. identify major ice ages and make assumptions on past climate conditions.

identify plants and make assumptions on past climate conditions.

Which factors of Earth's position would contribute to long-term climate change? its elliptical orbit and the tilt on its axis its distance from other planets and the tilt on its axis the tilt on its axis and its distance from the moon its distance from the moon and its elliptical orbit

its elliptical orbit and the tilt on its axis i

Which played a major role in altering wind patterns and ocean currents? volcanic eruptions ice ages movement of continents solar flares

movement of continents

What should scientists consider when studying tree rings to understand the variations in the local climate? patterns in their width, their density, and their composition odor from the wood, patterns in their width, and their density their composition, odor from the wood, and patterns in their width their density, composition, and location

patterns in their width, their density, and their composition

What do scientists study to reconstruct past climate conditions? tree branches, pollen grains, and rain water pollen grains, tree rings, and fossils rain water, tree rings, and fossils fossils, pollen grains, and tree branches

pollen grains, tree rings, and fossils

What do glaciers deposit that helps scientists study ancient climates? plants that produce pollen grains rocks formed from lava sediment that contains fossils animals that migrate

sediment that contains fossils

What are sunspots? storms on Earth's surface storms on the Sun's surface hot gases on the Sun holes in the Sun

storms on the Sun's surface

What is a fossil? the remains of an animal or plant preserved within a layer of rock a large body of compacted ice formed over thousands of years the energy radiated from the Sun a change in the structure of Earth's surface

the remains of an animal or plant preserved within a layer of rock

What most likely caused the ice ages? the size of tree rings and the amount of pollen grains solar flares and gassy ejections from the Sun the tilt of the Earth's axis and the shape of its orbit the temperatures of the Sun and moon

the tilt of the Earth's axis and the shape of its orbit

What is the relationship between Earth's temperature and the number of sunspots that occur? An increased number of sunspots causes an increase in Earth's temperature. A decreased number of sunspots causes an increase in Earth's temperature. An increased number of sunspots causes Earth's temperature to remain constant. A decreased number of sunspots causes Earth's temperature to remain constant.

An increased number of sunspots causes an increase in Earth's temperature.

What effect does the release of volcanic gases and ash into the air have on long-term climate? It allows radiation to seep through the ozone and lowers temperatures. It causes temperatures to rise. It reflects solar energy back into space and lowers temperatures. It causes rainstorms.

It reflects solar energy back into space and lowers temperatures.

Which statement best explains how tectonic activity affects long-term climate change? Volcanic eruptions can cause both global warming and global cooling. The movement of continents changes wind patterns and ocean currents. The change in Earth's tilt and its orbit around the Sun cause climate change. The increase of sunspots increases Earth's temperature.

The movement of continents changes wind patterns and ocean currents.

How do scientists study pollen grains to help them understand climate change? by analyzing and making inferences about them by observing and listing facts about them by studying and reading more about them by inspecting them and sharing findings with other scientists
