00:00.000 --> 00:12.480
Weathering is the breakdown of rocks at the Earth's surface through physical, chemical,

00:12.480 --> 00:17.640
and biological means.

00:17.640 --> 00:22.320
Physical weathering happens when rocks are cracked and broken apart by temperature changes,

00:22.320 --> 00:25.440
like freezing and thawing.

00:25.440 --> 00:31.040
Physical weathering occurs when minerals in rocks react with water, air, or other chemicals

00:31.040 --> 00:36.720
leading to the rocks decomposition.

00:36.720 --> 00:41.160
Biological weathering involves plants, animals, and microbes.

00:41.160 --> 00:47.840
Tree roots, for instance, can grow into cracks and split rocks apart.

00:47.840 --> 00:52.640
Once rocks are broken down by weathering, erosion takes over.

00:52.640 --> 00:58.320
Wind is the movement of these particles by wind, water, or ice.

00:58.320 --> 01:06.240
Wind erosion gradually carves out unique features, like natural arches and rock pillars.

01:06.240 --> 01:13.040
Fluvial erosion caused by rivers and streams, shapes valleys and canyons.

01:13.040 --> 01:19.880
Coastal erosion, driven by waves and tides, sculpts coastlines and cliffs.

01:19.880 --> 01:25.800
In colder regions, glacial erosion is a powerful force, carving out fjords and leaving

01:25.800 --> 01:28.320
behind marines.

01:28.320 --> 01:35.440
Together, erosion and weathering continually shape our planet, creating the diverse and beautiful

01:35.440 --> 01:38.520
landscapes we see today.

01:38.520 --> 01:44.080
Understanding these processes helps us appreciate the dynamic nature of Earth's surface.
