inner core. The core in the layers of the earth serves as the central region.
The mantle is the earth’s solid bulk in terms of its interior. The inner and
outer core are composed minerals and are the third and fourth layer in the
earth.
Answer:
(-1,-3) on the coordinate grid.
Explanation:
The location from where Sam started his morning walk is 3 units to the left and 2 units up from the origin. This location is indicated by the point (-3,2).
He walked 5 units south and met his friend Joshua.
So, find the point that is 5 units to the south of point (-3,2). Distances north and south on the map represent a change in the y-coordinate. Moving 5 units to the south on the map from point (-3,2) places the new location at point (-3,-3).
Sam then walked 2 units east, where he met his friend, Ethan.
So, find the point that is 2 units to the east of point (-3,-3). Distances east and west on the map represent a change in the x-coordinate. Moving 2 units to the east on the map from point (-3,-3) places the new location at point (-1,-3).
So, Sam met Ethan at the location indicated by point (-1,-3) on the coordinate grid.
