What evidence do astronomers use to support the support the hypothesis that there was once tectonic activity on Mercury Venus and Mars?
maybe because planets are stupid
Why did early astronomers think that mercury was two separate planets?
early astronomers thought that Mercury was a seprate planet to another because it was so small
What did radar astronomers find in the polar regions of Mercury?
Radar astronomers found ice water that never melts in the deep craters in the polar regions of Mercury.
What does it mean when you say Mercury is geologically dead?
The moon, Mercury, and Mars are all so small that over time they have lost much of their internal heat and have become geologically dead. Unlike the Earth which is geologically alive, mercury has no tectonic or core activity. There are no tectonic plates There are no volcanos There is no wind erosion There is no frost erosion There are no rivers and therefore no water erosion There is no change due to living organisms eg sedimentation
How do scarps on Mercury differ from geological faults on Earth?
Scarps are thought to have been formed when the planet's iron core cooled and contracted, causing the crust to crack. Faults on Earth are the result of tectonic activity.

Why is it hard for astronomers to learn about the planet Mercury?
cause they can't go there
Are lava flows on mercury?
No. There is no volcanic activity on Mercury.

Who named Mercury and why did they choose the name Mercury?
Mercury was named by astronomers in 4th century BCE. The name comes from the Roman god Mercury, who was the messenger god and the fastest of the gods.
MERCURY IS so dense astronomers believe its has a high concentration of what element?
iron
Does mercury have volcanic or storm activity?
No. Mercury does not have volcanoes or storms.
What is basic composition on mercury?
Astronomers have estimated that the Mercury composition is made up of approximately 70% metals and 30% silicate material.
