An example of an activity space is a public park where people engage in various activities such as picnicking, jogging, playing sports, and walking their dogs. This space provides opportunities for social interaction, relaxation, and physical exercise for individuals within the community.
Scientific observations, experiments, and calculations show that Earth orbits the sun due to the gravitational pull between the two bodies. This theory is supported by various sources of evidence, including the motion of celestial objects, the effects of gravity, and the concept of elliptical orbits.
The microwave energy that fills all of space primarily originates from the Big Bang, which occurred approximately 13.8 billion years ago. This energy is a remnant of the hot, dense state of the early universe and is now observed as the Cosmic Microwave Background (CMB) radiation. As the universe expanded and cooled, this radiation stretched and cooled to the microwave wavelengths we detect today. The CMB serves as a crucial piece of evidence for the Big Bang theory and provides insights into the early conditions of the universe.
The sun does not directly help us walk. Walking is a physical activity that our muscles and nerves control. However, the sun's warmth and light can provide us with energy and vitamin D, which are important for overall health and may support physical activity like walking.

The rocks of Earth's crust, especially sedimentary rocks
The process of radiometric dating provides some of the best evidence that Earth has evolved over geologic time. By measuring the decay of radioactive isotopes in rocks and minerals, scientists can determine the absolute age of geological materials, helping to establish a timeline of Earth's history.
I have no ide that’s the answer
Constructing a geologic column is useful in Earth science because it provides a visual representation of the Earth's history and the sequence of events that have occurred over time. It helps scientists understand the relative ages of rocks and fossils, as well as the processes that have shaped the Earth's surface. By studying the geologic column, researchers can reconstruct past environments, track geological changes, and make predictions about future events.

The geologic time scale provides a chronological framework for understanding the history of Earth, including the evolution and extinction of various life forms. It categorizes Earth's history into distinct time intervals based on major geological and biological events, helping us track the appearance and disappearance of different life forms over millions of years.
The information the geologic scale provides is animals and fossils over time and periods. Major divisions of time is called eras.
A change in position is evidence that motion happened.
The 3 main ideas are, 1. The rock record provides evidence of geologic events and forms of the past. 2. Processes observed on Earth in the present also acted in the past. and 3. Earth is very old and has changed over geologic time.
The presence of folded and faulted rock layers, with layers appearing deformed and displaced, provides direct evidence of crustal plate collision in a region. These structures are typical results of the immense forces generated during plate collision, causing the Earth's crust to deform and buckle.
