From the standpoint of geography, your mental map is your visualization of the spaces you come across.
Explanation:
In the sphere of behavioural geography, the phrase "mental map" stands for a person's viewpoint or perception of his/her area of interaction. Though it might seem like a subject matter that would be studied by social sciences fields, it is mostly studied by modern-day geographers. Mental maps are important as they provide people with crucial means of making sense of the world. They also help in storing and recalling information about the patterns of the Earth's physical and human characteristics. Example: Picturing one's neighbourhood, one can visualize where the roads go and where the houses are located including landmarks.
On the oceans of the Earth, gravity and inertia work in opposition, causing tidal bulges on opposite sides of the planet. The moon's gravitational force pulls the ocean's waters toward it on the "near" side of the Earth (the side facing the moon), resulting in a bulge.
