The evidence provided by the fossils means that Trilobites became extinct 252 million years ago and lived on Earth more than 521 million years ago.
Basically, a fossil is a remains which gives geologist information about the organism which lived in the past because when those organism dies, they decay and remain on or in the earth surface
Since the trilobite fossils are found in rock that are 521 million years and 252 million years old, then, it means that:
- Trilobites became extinct 252 million years ago therefore, no other remains keep existing on rocks earlier.
- Trilobites lived on Earth more than 521 million years ago
Therefore, the Option A and D is correct.

The arrows of circulation that most affect the US climate are the arrows on the left side of the northern hemsphere. In the attached image below you can see these cetas highlighted by a pink square.
Explanation:
As shown in the question above, the Coriolis Effect is an atmospheric phenomenon that modifies the direction of wind circulation in the terrestrial globe, completely modifying the climate of the regions. This phenomenon occurs due to the rotation of the earth on its own axis, which has the ability to create a reference system for this rotation.
The Coriolis effect has the ability to change the direction of winds within the hemispheres. This causes winds in the southern hemisphere to turn clockwise while winds in the northern hemisphere turn counterclockwise.
The US is located in the northern hemisphere, on the left side of the globe, as shown in the attached figure below.
