a student claims that studying rock layers on the side of a mountain would show how earth has changed over geologic time. which type of evidence from the rock layers best supports this claim? some rock layers contain fossils of plants, and other rock layers contain fossils of marine animals. rock layers are composed of sand and silt and are found in different locations. some rock layers are solid, and other rock layers have holes that store water. rock layers that are thick and smooth are deeper than rock layers that are thin and rough.

Answer

Answer:

Some rock layers contain fossils of plants, and other rock layers contain fossils of marine animals.

Explanation:

Step1: Identificar la idea central

El estudiante sostiene que la Tierra ha cambiado geológicamente.

Step2: Analizar las opciones

Las capas de roca con diferentes tipos de fósiles indican cambios en el entorno a lo largo del tiempo. Las capas con fósiles de plantas sugieren ambientes terrestres, mientras que las con fósiles de animales marinos indican ambientes marinos. Esto muestra que el entorno ha variado, lo cual apoya la idea de que la Tierra ha experimentado cambios geológicos. Las otras opciones no indican cambios geológicos de la misma manera. Las capas de arena y limo en diferentes ubicaciones pueden ser resultado de procesos sedimentarios normales, y las características físicas de las capas de roca (como huecos, espesor y textura) no son evidencia directa de cambios geológicos a lo largo del tiempo como lo son los fósiles.
