The inner planets are;- Mercury, Venus, Earth and Mars. Earth is the only planet which has atmosphere, water on the surface or know of to have water(Mars might have water underground), and life.
Mercury is pretty much a small planet on fire by day, but freezes at night.
Venus is a gas planet which is usually on fire in places too, but has mass ice craters on the surface.
Earth, well just look out your window.
Mars may have been an earth like planet at one stage, (still unknown) but is known as the red planet due to its volcanic activity. Mars also has the biggest mountain/volcano on any known planet called Mt Olympus. It's 3 times the size of Mt Everest.
Hope this helps!! :)
Answer:
An unconformity shows where some rock layers have been lost because of erosion. To date rock layers, geologists first give a relative age to a layer of rock at one location and then give the same age to matching layers at other locations. Certain fossils, called index fossils, help geologists match rock layers.

Answer:
The magnitude of the car's acceleration as it slows during braking is 36.81 m/s²
Explanation:
From the question, the given values are as follows:
Initial velocity, u = 90 m/s
final velocity, v = 0 m/s
distance, s = 110 m
acceleration, a = ?
Using the equation of motion, v² = u² + 2as
(90)² + 2 * 110 * a = 0
8100 + 220a = 0
220a = -8100
a = -8100/220
a = -36.81 m/s²
The value for acceleration is negative showing that car is decelerating to a stop. The magnitude of the car's acceleration as it slows during braking is therefore 36.81 m/s²
