How does knowing the age of a lunar rock help astronomers estimate the age of the surface of a planet with no atmosphere?
Because there is no atmosphere, no erosion has taken place, so lunar rocks are the same today as they were when they (and the Moon) were formed.
Also to what this other person wrote:
By knowing the rate of cratering, scientists are able to use the number of craters on the surface of any body to estimate how old its surface is-- without having to bring back rock samples. The lunar rocks brought back during the Apollo missions were found to be about 4.6 billion years old. Because these rocks have hardly changed since they formed, we know the solar system itself is about 4.6 billion years old.

How do astronomers determine the surface temperatures of the stars?
Astronomers determine the surface temperatures of stars by analyzing their spectrum of light. Each star emits a unique spectrum based on its temperature which can be measured using instruments like spectrographs. By comparing the observed spectrum to known temperature profiles, astronomers can estimate the surface temperature of a star.
What happens to impacts on the surface of bodies without an atmosphere?
W/o an atmosphere to erode them, they stay fresh. because scientists now know the age of the moon, they can count the number of impacts craters to find the rate of the cratering science the birth of our solar system. by knowing the rate of crating, scientists are able to use the number of the craters on any body of water to estimate how old the body of water is. this is easier because sceintsts don't need to bring back the rock to find out.
This holds a planet's atmosphere close to its surface?
Gravity holds a planet's atmosphere close to its surface. The gravitational force of the planet's mass prevents the gases in the atmosphere from escaping into space. Without gravity, the atmosphere would disperse into space.
The earths surface transfers heat to the atmosphere primarily by?
The Earth's surface transfers heat to the atmosphere primarily by convection and radiation. As the surface heats up, air in contact with the surface warms up and rises, creating vertical currents of warm air. At the same time, the Earth's surface emits radiation in the form of heat, which is absorbed by the atmosphere.
Does the earths atmosphere extend about 1 kilometer above its surface?
No, the Earth's atmosphere extends much higher than 1 kilometer above its surface. The exosphere, the outermost layer of the atmosphere, extends up to 10,000 kilometers above the Earth's surface.
Can astronomers tell from the elements of a star what uts surface temperature is?
Yes, astronomers can estimate the surface temperature of a star based on its spectral type, which is determined by the elements present in its atmosphere. Each spectral type corresponds to a range of surface temperatures, allowing astronomers to make an educated guess about a star's surface temperature.

Will New technologies allow astronomers to use X-ray telescopes on Earth's surface?
We had best hope the answer is 'no'. In order to use x-ray telescopes effectively from the earth's surface, you'd have to get rid of the atmosphere.

Why calculate leaf surface area with transpiration?
Calculating leaf surface area helps estimate the total surface available for transpiration. Transpiration is the process where water is evaporated from the surface of the leaf into the atmosphere, which is important for plant cooling and nutrient uptake. By knowing the leaf surface area, we can better understand the potential transpiration rate and overall water requirements of the plant.
What were astronomers able to photograph Mars' surface easily?
The reason astronomers were able to photograph the surface of Mars is due to probes, unmanned spacecrafts used for exploration in space.
Why can astronomers see the surface of mars clearly not the surface of Venus?

What is the atmosphere on the surface of Venus's?
The atmosphere on the surface of Venus is cloudy.
What is The source of light that enables astronomers to see Jupiter through a telescope?
The primary source of light that enables astronomers to see Jupiter through a telescope is sunlight reflecting off the planet's surface and atmosphere. Jupiter also emits its own light, known as intrinsic radiation, which contributes to its visibility in the night sky.
What methods did astronomers use to study the entire surface of the moon?
Orbiting satellites.
What keeps Earth's atmosphere close to the surface?
The gravitational pull keeps the Earth's atmosphere close to the surface...
What is the faint outer atmosphere of the sun?
The faint outer atmosphere of the sun is called the corona. It is visible during a total solar eclipse as a halo of light around the sun. The corona is much hotter than the surface of the sun and extends millions of kilometers into space.
