Earth's surface features, such as mountains, valleys, rivers, and Coastlines, reveal the planet's dynamic history through processes like erosion, sedimentation, volcanism, and tectonic activity. For example, the formation of mountain ranges indicates tectonic uplift, while river valleys showcase erosion over time. Fossils embedded in sedimentary layers also provide clues about past environments. By studying these features, scientists can reconstruct geological timelines and understand how Earth's landscape has evolved.

If a planet has a surface with craters but lacks other geological features, it suggests that the planet may be geologically inactive, with little to no tectonic or volcanic activity. The craters indicate past impacts, likely occurring over a long period, while the absence of other features might imply a lack of processes like erosion or weathering. This could suggest that the planet's interior is solid and stable, possibly composed of ancient rock formations that have not been significantly altered over time. Additionally, it may indicate that the planet has cooled and solidified, preventing further geological changes.
Flat land features have a low elevation and minimal changes in height, creating a horizontal surface. Hilly land features, on the other hand, have multiple elevations with various slopes and inclines across the terrain.
Earth's shadow on the moon proved that earth wasn't flat. When galileo first turned his telescope to the moon, he found a surface scarred by craters and maria. Before that time, many people believed that all planetary bodies were "perfect" without surface features.
A topographic map displays changes in elevation at Earth's surface through the use of contour lines. These lines connect points of equal elevation, allowing viewers to visualize the landscape's terrain and features.

due to weathering, the earth's surface wears away, the sills and dykes form escarpments and batholith forms granite.

Geography changes the physical characteristics, especially the surface features, of an area due to the weather.
Three events that might signal a volcanic eruption are changes in earthquake activity, volcano surface bulges, and increased gas emissions. These changes can indicate rising magma beneath the surface, which may lead to an eruption.
Topography refers to the study or detailed description of the surface features of a region, including its elevation, shape, and terrain characteristics. It is often depicted on maps using contour lines to show changes in elevation and land features.
Mars shows signs of water erosion on its surface, including features like valleys, river channels, and delta deposits. These indicate that liquid water flowed on the planet's surface in the past.

Geomorphologists study the surface of the earth. They conduct scientific studies of landforms and their shapes to understand landform history and to be able to make predictions about changes through the use of various scientific methods, such as numerical modeling, field observations and experimentation .
